Definitions
- the invention concerns parts of a paper or board or finishing machine that are subjected to intensive wear when they are in contact with moving fabrics and with the paper web in a paper machine as well as a method for manufacture of such wearing parts or pieces.
- doctor blades or coating blades are made of a hard metal, plastic, or of a carbon-fibre reinforced or fibreglass-reinforced material.
- water drain ribs and other ribs in the wire part and in the press section in paper and board machines are also problematic.
- the base face must be highly resistant 2 to corrosion, have small pores, and be resistant to wear.
- a fabric in the paper machine such as a felt or a wire, runs across the face, which fabric includes abrasive minute particles, such as fillers of the paper and impurities from the process water.
- ceramic bits, sprayed ceramics, or hybrid structures which consist of combinations of different materials as well as electrolytic plating, such as hard-chromium plating, have been used.
- Compact ceramic ribs prepared by sintering are produced by gluing and/or mechanical joining together of smaller ceramic bits and by then gluing or mould-joining them onto a fibreglass-reinforced plastic rib.
- a ceramic coating can also be prepared by thermal spraying.
- a problem is, however, the higher porosity of sprayed ceramic and in some cases also lower hardness.
- sprayed ceramic materials are used, there is a risk of wear of the wires.
- Applications of use have, however, been found for thermally sprayed ribs in applications in which the machine speeds are lower, in which the rates of abrasion of plastic ribs are excessively high, and in which an embodiment with ceramic bits is again unduly expensive.
- PVD Physical Vapour Deposition
- the base material for a piece to be coated is typically hardened steel, high-speed steel, or sintered hard metal, whose hardness has been chosen so that it is suitable for the situation of wear in the conditions of operation, usually so that the components have a considerable service life even without coating.
- a thin, hard coating is formed out of a metal vapour from a source of coating and out of an ionized reactive gas used in the process, such as nitrogen, as the vapour and the gas are condensed on the face of the piece during simultaneous ion bombardment.
- PVD coating processes include, among other things, ion coating, magnetron sputtering, vacuum vaporization, and ion implantation, of which the first two are those that have been used most commonly. All of these processes are what is called vacuum coating processes.
- the magnetron sputtering process has been described in more detail, for example, in the patent publication WO 91114797.
- the commonest PVD coating materials are titanium nitride, titanium carbonitride, titanium aluminonitride, chromium nitride, tungsten carbide/carbon, and diamond-like coatings (DLC).
- the object of the present invention is parts or pieces of a paper or board machine that are subjected to intensive mechanical wear and a method for manufacture of such pieces in view of producing a highly wear-resistant coating which is as thin as possible and as economical as possible.
- the problems that occur in connection with the prior-art solutions can be solved by using the PVD coating technology for manufacture of parts and pieces of a paper/board machine that are subjected to wear.
- the base material it is possible to use a corrosion-proof material, stainless steel, carbon steel, alloyed or non-alloyed steel, thermosetting plastic or thermoplastic resin, or a composite material, which material has an adequate rigidity in its application of use. Further, if necessary, it must be reasonably possible to machine the base or bottom material to the shape of the desired object.
- a sufficiently thick intermediate layer or carrying layer is prepared or coated in order that a particle that causes abrasive 4 and/or erosive wear should not be able to penetrate into the base material and to split off the coating.
- the carrying layer is typically prepared either electro lytically by hard-chromium plating or auto-catalytically by means of chemical nickel.
- the carrying layer may also have properties protecting from corrosion. In applications in which the hardness of the base material is sufficient, the carrying layer is optional and can be omitted.
- the base material is soft, for example a reinforced or non- reinforced polymer material, a carrying layer is also needed to provide a homogeneous adhesion base so as to obtain a uniform final result and to protect the base material from possible damage.
- a very hard, wear-resistant face is prepared by means of a PVD process.
- a hard, low-friction coating is applied onto the face of the piece.
- the coating material can be, for example, titanium nitride, titanium carbonitride, titanium aluminonitride, chromium nitride, or a coating with low friction, such as a tungsten carbide/carbon coating, or a diamond-like (DLC) coating, or multi-layer coatings of those mentioned above.
- a very hard coating is prepared advantageously by means of a magnetron sputtering process.
- a coating prepared with the PVD process can also be several coatings prepared with the PVD process one above the other, made of the same material or of different materials.
- a coating prepared by means of the PVD process differs clearly from a corresponding thermally sprayed coating, which is clearly more porous, thicker, and of inhomogeneous thickness. Also, a thermally sprayed coating must always still be machined after coating.
- the hardness of the base material of the piece can vary in a range 180...230 HV.
- the hardness of the carrying layer may vary in a range 800...1000 HV, and the thickness of the carrying layer may vary in a range 10...100 ⁇ m.
- the hardness of the PVD coating i.e. of the ultra-hard coating, may vary in a range 2000...3000 HV, and its thickness may vary in a range 0.5...25 ⁇ m. With diamond-like coatings (DLC), it is possible to achieve hardness levels of up to 6000...10000 HV.
- the advantages of the solution in accordance with the present invention include low cost of production in the process, because the whole piece does not have to be made 5 of an expensive material of special hardness, but a less expensive material can be used as the base material, and a hard and durable coating is applied onto the base material. Also the cost of the hard-chromium plating and auto-catalytic coating needed in the carrying layer is relatively low, and suitable applications are abundant- ly available. With a PVD process, the thickness of the coating is uniform all over, so that, in the case of a coating or of a multi-layer coating, the shape of the surface of the coated piece complies with the shape of the face placed under the outermost coating layer.
- the piece is coated by means of a PVD process over its entire operational area of wear. If it is desirable to regulate the wear in a controlled way, it is possible to use coatings with different levels of hardness at different locations on the piece.
- a PVD-coated piece does not require mechanical working, machining, or finishing, but it is as such ready for use after the coating. At present, PVD coating equipments also suitable for larger pieces are already available.
- the wear-resistant solution in accordance with the invention can be applied favourably to the manufacture of applicator bars, which bars are used, for example, in surface sizing and film coating applications in SymSizer and SymCoat equipments (Valmet Corporation).
- a conventional hard-chromium plated bar out of a base material of stainless or acid-proof steel, a smooth or grooved bar is manufactured by means of conventional methods, an electrolytic or auto-catalytic coating is applied as a carrying layer onto the bar, and as a typical example of the former coating can be mentioned hard-chromium plating, and of the latter coating, chemical nickel.
- an ultra-hard PVD coating such as, for example, titanium nitride or titanium aluminonitride or multi-layer coatings of the above or out of diamond-like coatings, or out of any other coating produced by 6 means of a PVD process
- a hard and low-friction coating is prepared.
- the base material it is necessary to use stainless steels, whose basic hardness is low and which do not provide an adequate hardness and a carrying layer for the thin hard coating. This is why a sufficiently thick, typically 10...100 ⁇ m thick, carrying layer is applied onto the stainless steel.
- an ultra-hard wear-resistant layer is applied by means of a PVD process, preferably magnetron sputtering.
- a PVD process preferably magnetron sputtering.
- good surface quality, resistance to corrosion, low porosity, and high resistance to wear are required. These properties are, however, not required throughout the entire thickness of the material, but from the surface layer only.
- the advantages of the applicator bar in accordance with the present invention include resistance of the coating to a thermal shock, good adhesion of the coating to the base material, and stability of the tolerances of the base material as the measures are not changed to a substantial extent because of the thin coating, which is an important advantage in particular in the manufacture of grooved bars.
- the solution in accordance with the invention can also be used favourably in a low- friction doctor blade or coating blade for a paper or board machine.
- the blades have been manufactured out of a hard metal, plastic, or out of a rib reinforced with carbon fibre or with fibreglass.
- the base material of a doctor blade or coating blade it is possible to use a metal, a composite, or a carbon- fibre or fibreglass reinforcement. If the base material is sufficiently hard, no carrying layer is needed in between; when softer base materials are used, a carrying layer is applied onto the face, the thickness of said carrying layer being 10...100 ⁇ m, preferably 50 ⁇ m.
- a wear-resistant ultra-hard PVD coating is applied, preferably by means of the magnetron sputtering method, and the coating is applied preferably to the wear area of the blade.
- the blade is provided with good surface quality, good adhesion, low friction coefficient, high hardness, and suitability also for faces of highly complicated cross- section.
- a doctor blade or a coating blade is obtained which has very low friction and is highly resistant to wear.
- the coating endures a thermal shock well, as compared, for example, with a coating with a ceramic tip. The coating adheres to the base material well.
- the tolerances of the base material are stable, because, owing to the thin coating, the measures are not changed to a substantial extent and, thus, there is no need to finish the blade.
- the blade has a very low friction coefficient, and the wear of the backup face is also little.
- the thermal expansion coefficients of the coating and of the base material are compatible with each other. This solution permits free design of the face. Different chamfers can be coated, and no multi-stage grinding is needed, as is needed in the case of blades with ceramic tips.
- the face is not porous, as is the face of a ceramic, and the face endures mechanical impacts considerably better than a ceramic does.
- the blade does not damage the roll coating.
- This technique also permits the use of low-energy coatings, such as molyb- denum sulphide.
- the doctor blades can also be coated again after they have been worn.
- the resistance to corrosion of the base material is not changed or deteriorated, because the coating temperature can be kept low, which is highly important, for example, in the case of steel, nor is the straight form of the base material changed out of this reason.
- the blades can be coated while winding them from one reel onto another in a vacuum chamber, in which case large vacuum chambers for coating are not needed.
- the base material to be coated is unwound from a first reel and wound onto a second reel, while the coating takes place in the area between 8 the reels. Owing to the low coating temperature, it is also possible to coat blades with carbon-fibre and fibreglass reinforcements.
- water drain ribs in a wire part and in a press section.
- water drain ribs for wire parts and press sections have been manufactured out of plastic, sprayed ceramic, ceramic bits, metal, or out of combinations of same.
- the base material stainless steels in view of achieving a resistance to corrosion of the water drain members, as the base material stainless steels are used, whose basic hardness is low.
- a sufficiently thick carrying layer typically of a thickness of 10...100 ⁇ m, is coated either by hard-chromium plating or auto- catalytically, for example, with chemical nickel.
- an ultra- hard, wear-resistant face is prepared by means of a PVD process, preferably magnetron sputtering.
- a carrying layer coating or a combination of coatings is applied, which has a hardness higher than the hardness of the base material, which base material is softer and can be worked readily, so that the surface layer of the blade can resist penetration of individual particles into the base material, the surface layer provides the PVD coating with a suitable adhesion base, the surface layer has a good surface quality, and the coating processes, including the coatings in the intermediate layer, do not change the measures of the rib to a substantial extent, and the surface layer has a low porosity and a low friction coefficient.
- the wear resistance proper is obtained with the PVD coating with which the intermediate layer is coated.
- Features typical of the PVD coating are good surface quality, good adhesion, low friction coefficient, very high hardness, and suitability for complex faces.
- the advantages of a PVD-coated water drain rib of a wire part or of a press section include excellent resistance of the coating to a thermal shock, good adhesion of the coating to the base material, stability of the tolerances of the base material as the measures are not changed to a substantial extent by the effect of the thin coating, low friction coefficient, low wear of the backup face, and the thermal expansion 9 coefficients of the materials can be made compatible with each other if the rib has been constructed out of different layers by means of mould joining.
- the coating is not porous, the resistance to corrosion and the alloying of the base material can be selected in compliance with the particular application, the resistance to corrosion of the base material, i.e. , for example, stainless steel, is not deteriorated, because the PVD coating temperature can be kept low, lower than 100 °C, the straight form of the base material is retained because of the low coating temperature.
- No adhesive joints are needed in the ribs, in which case fillers do not adhere to the ribs and cannot cause an abrading effect. A what is called piano key effect does not occur.
