Definitions

the present invention relates to a wear and corrosion resistant Surface or a wear and corrosion resistant Coating, a steel alloy for coating a ceramic, metallic or other object as well Process for producing a wear and corrosion resistant Coating.
CVD chemical vapor deposition
PVD physical vapor phase deposition
thermal spraying ion beam processes
laser coatings build-up welding
electrolytic and chemical coatings Conventional hard material layers are often brittle, such as aluminum oxide (Al 2 O 3 ), tungsten carbide-cobalt (WC-Co), diamond-like layers (DLC's), etc., whereas highly corrosion-resistant materials such as molybdenum or chromium are often not hard enough.
steel alloys are often used used for relatively thick and inexpensive coatings.
the main advantage of iron-based alloys consists in the high ductility compared to ceramics and hard metal coatings. Good corrosion resistance, high Toughness, hardness and good processability are further Advantages.
the abrasion resistance is rather moderate, but acceptable for a variety of applications.
An improvement the abrasion resistance or the wear resistance can be achieved are made by reinforcing the steel alloy, for example by adding nitrogen to that too applying steel alloy wettable powders.
the object of the present invention is based on a novel coating material or a new, on Iron based alloy significantly improved surfaces for simultaneous wear and corrosion protection to be able to.
the object is achieved by means of a wear and corrosion-resistant surface or a wear and corrosion-resistant coating, in particular according to claim 1, solved.
Chromium is one of the crucial elements for increasing the corrosion resistance.
the chromium content should be between 12% and 25% so that sufficient effect can be achieved.
Chromium stabilizes the ferritic crystal structure.
Manganese suppresses the formation of delta ferrite and increases it Nitrogen solubility. However, excessive manganese levels promote Formation of intermetallic phases and deteriorate Corrosion resistance.
the manganese content should be between 0% and 15% lie.
molybdenum is the second decisive element for Increase in corrosion resistance. Too high a molybdenum content however leads to the formation of delta ferrite and increases the Elimination tendency of sigma phases.
the molybdenum content should are between 2% and 6%.
Nickel is usually the decisive element for the setting of an austenitic crystal structure.
the nickel content in the nickel-containing alloy should not exceed 15%, whereas the nickel-free alloy obtains its austenitic crystal structure through the addition of nitrogen (N).
Vanadium is one of the most nitrogen-affecting alloy elements.
the vanadium content should be between 1%, preferably 2 %, and 12% are.
the vanadium dissolved in the alloy forms with nitrogen hard phases (vanadium nitrides, VN), which in turn not only the wear but also the one Significantly increase corrosion resistance.
the one in the solution homogeneously excreted hard phases (VN) have typical sizes in the range from 10 to approx. 5,000 nm.
Nitrogen is one of the most important alloying elements. It increases the alloy types 1 to a large extent austenitic crystal structure. Nitrogen forms with the in the desired hard phases in the alloys dissolved vanadium (Vanadium nitrides, VN).
the alloys mentioned is the nickel equivalent Ni ⁇ equal to or greater than the chromium equivalent Cr ⁇ minus 8, ie Ni ⁇ ⁇ Cr ⁇ - 8 , the alloy is non-magnetic because there are enough elements, such as nitrogen or nitrogen and nickel in the alloy, which stabilize the face-centered cubic, austenitic crystal lattice.
the surfaces or coatings according to the invention have the following chemical compositions (in percent by mass): Chrome (Cr) 12 to 25% Manganese (Mn) 0 to 15% Molybdenum (Mo) 2 to 6% Nickel (Ni) 0 to 15% Vanadium (V) 1, preferably 2 to 12% Nitrogen (N) 0 to 5%, the rest iron and technically usual impurities, optionally with up to a total of 5% of the elements copper, cobalt, niobium, titanium, zirconium, silicon, tungsten.
this is used to form the hard phases amount of nitrogen required before coating, for example brought into the alloy by means of thermal spraying and when applying resp. Syringes kept in the alloy.
This is for the application or Syringes needed
Steel alloy preferably in powder form with which desired chemical composition.
Such steel powder are usually commercially available, preferably the grain size range is typically 5 to approx. 120 ⁇ m.
this is used to form hard phases amount of nitrogen required during coating, such as for example thermal spraying, the steel powder in introduced the alloy. Nitrogen is released during the coating process, such as the spraying process, so to speak inflated, i.e. Nitrogen is used, for example, as a plasma or Reaction gas used.
the nitrogen diffuses into the wear and tear corrosion-resistant surface into the nitride hard phases to build.
thermal spraying All three application methods have in common that they are suitable for so-called thermal spraying.
the following illustration shows all thermal spraying processes by means of which the steel alloys defined according to the invention can be applied, for example, to a ceramic, metallic or other surface, to form the wear and corrosion-resistant surfaces defined according to the invention.
Steel powder with the chemical composition Fe17Cr10Mn4Mo6V in the grain size range from 5 to 106 ⁇ m was in a rotary nitrogen oven embroidered to a nitrogen content of 2 to 4% and then thermally sprayed.
the same alloy composition was without prior embroidery, however with nitrogen supply during the thermal spraying process, deposited. In the end, the same thing happened again Starting material thermally sprayed and subsequently the required Amount of nitrogen supplied.
the resulting structure of the surface layers achieved in this way is marked by a in all cases austenitic non-magnetic matrix with embedded hard phase of the vanadium nitride (VN) type.
VN vanadium nitride
Steel powder with the chemical composition Fe16Cr8Mn2.5Mo8Ni4V in the grain size range from 5 to 106 ⁇ m was in a rotary nitrogen oven to a nitrogen content embroidered by 3 to 4% and then thermally sprayed.
the same alloy composition was used without previous Nitrification, but with nitrogen supply during the thermal spraying process, deposited.
the same source material was finally thermally sprayed and subsequently supplied the required amount of nitrogen.
the resulting structure of the surface layer achieved in this way is characterized by an austenitic in all cases non-magnetic matrix with two families of embedded Vanadium nitride (VN) hard phases.
the first phase exists from primary nitrides in the order of a few micrometers.
the second phase consists of secondary nitrides in the order of magnitude of a few nanometers.
the same alloy composition was without prior embroidery, however with nitrogen supply during the thermal spraying process, deposited. In the end, the same thing happened again Starting material thermally sprayed and subsequently the required Amount of nitrogen supplied.
the resulting structure of the surface layer achieved in this way is characterized in all cases by a martensitic Matrix with two families of embedded hard phases of the vanadium nitride (VN) type.
the first phase consists of primary nitrides on the order of a few micrometers.
the second Phase consists of secondary nitrides on the order of a few nanometers.
VN cubic vanadium nitrides
chrome (Cr), molybdenum (Mo) and nitrogen (N) the layers receive a high level of corrosion protection.
the waiver of the alloying element allows Nickel (Ni) used in an austenitic alloy Areas where nickel allergies can otherwise be triggered. This is especially true for applications where skin contact or contact with Parts of the human body is possible.
the surfaces or coatings according to the invention in accordance with the proposed alloys include applications in those areas where high wear and corrosion protection with simultaneous ductility are required.
the alloys can thus be used in the following industries, for example:
