Definitions
- HT hard particles
- AT abrasive particles
- the effectiveness of HT is optimal if it (a) is harder than the attacking ones AT, (b) larger than the furrow cross section, (c) dispersed in the metal matrix (MM) and (d) firmly connected to the MM IM
- a dispersion of the HT means that they are arranged at a medium distance from each other in the MM and consequently do not touch each other. This leads to the shortest average grooving length in the matrix and to the greatest fracture toughness of the composite material. Setting a dispersion is not trivial and depends on the volume and diameter ratio of the HT and MM powders IM
- the bond between HT and MM is formed by interdiffusion during hot compacting. It is generally stronger for HT made of metal / metalloid compounds than eg for metal oxides. B, C and N are used as metalloids, some are used as metals the subgroups of the 4 to 6 period, with titanium being of particular interest because of its availability and because of the high stability and hardness of its metalloid compounds.
- the requirements (a) to (d) can only be met together with a metal matrix-particle composite.
- Ferro alloys are used to alloy steel. In order to reduce the refining costs, an iron content remains in the ferro alloys, which is why they are not only inexpensive, but also brittle after solidification and can be comminuted to a desired powder grain size.
- carbide particles TiC, NbC, VC
- the external shape and size as well as the distribution of the carbide particles in the MM corresponds to that of the ferroalloy particles. Local melting can occur in the core of the carbide particles formed in situ tongues occur
- the carbon required for carbide formation is not mixed in, but is added to the matrix powder, ( ⁇ ) the carbon required for carbide formation is added to the powder mixture by carburizing in a gas phase, ( ⁇ ) instead of carburizing, an embroidery in a gas phase carried out to convert the ferroalloy particles into nitrides (TiN, NbN, VN)
- the process according to the invention is distinguished from known processes by the following advantages (1)
- the HT formed in-situ reach a high hardness of 2000 to 3000 HV (2) They are produced in-situ from inexpensive ferroalloy particles and in a size that is known as carbide or Nitrides are only available as agglomerated powder, but agglomerated HT do not have sufficient internal strength to withstand furring abrasive particles (3)
- the high wear resistance of the composite material according to the invention, formed in situ, is explained in comparison to known composite materials using an exemplary embodiment.
- the hardenable steel 56NiCrMoV7 with an average powder grain size of 55 ⁇ m was used as the matrix powder.
- the hot isostatic pressing of the evacuated powder capsules to full density took place at 1100 ° C for 3 hours an all-round pressure of 140 MPa instead of Subsequent hardening and tempering, a matrix hardness of around 700 HV was set
- Chromium diboride is in Comparably coarse grit available, but tends to dissolve in the matrix and achieves a lower wear resistance (B) Titanium diboride is even harder than titanium carbide, but does not offer increased wear resistance (C) due to the too small particle size.
- FIG. 1 shows the same in-situ formation of TiC particles as for A.
- c, d schematic representation and description of the phase components, the fields labeled Fe, Ti (appearing bright in (a) and (b)) contain more iron , and less carbon than TiC and are partly eutectically solidified. At lower temperatures there are no liquid components.
