Definitions
- valve seat rings from the very hard and wear-resistant Co and / or Co / Mo base alloys, the valve seat rings not being individually manufactured in a known manner and fitting into the cylinder heads, but rather being deposited directly onto the base material of the cylinder head , Arc wire spraying (LDS) is used as the deposition process, the starting material not the alloy but the components used which form the desired alloy during the deposition process.
- LDS Arc wire spraying
- Alloys at least one element from the group Cr, W, Ni, Fe, Si, Mn in an amount of 0.1 to 20% by weight. Furthermore, the impurities customary for the corresponding metals can be present in traces.
- the nominal composition (% by weight) of particularly preferred Co-based alloy is as follows: C: 0.1 to 3% Cr: 5 to 30% W: 0 to 20%
- the injection molded valve seat rings according to the invention are significantly lighter or less thick. In this way, savings in the relatively expensive raw materials Co and Mo can be realized in an advantageous manner.
- the individual components are fed through one or more metallic cored wires and melted in an arc in a known manner.
- the individual components are mixed and the preferred alloys are formed.
- This co-rich component usually forms the sheath of a filler wire filled with powdery fillers. If necessary, however, it can also be expedient to use a composite wire which is composed of a Co-rich matrix and disperse further components. In contrast to cored wire with co-sheath, the composite wire has metallic Co or Co alloy distributed over its entire cross-section. The vast majority of the others Alloy components are encased by the co-matrix or at least partially in contact with it.
- the sheath of the cored wire consists of a Co / Fe alloy with an Fe content of 1 to 3% and a core of filler material powder.
- two wires, a filler or composite wire and a solid wire are used, the solid wire being formed from at least one of the components forming the filler wire.
- This solid wire is preferably made of Ni or Cr, or their alloys.
- a preferred method of building up the cored wires according to the invention is based on co-foils or co-strips. The powdery components and possibly a solid wire are applied to the Co-tape, rolled up parallel to the longitudinal axis, crimped and drawn out to form the cored wire.
- the wire can be constructed as a solid wire or also as a filler or composite wire.
- a protective gas is preferably used as the process gas of the arc wire spraying.
- N 2 or Ar is particularly preferably used here.
- the valve seat rings or coatings made of Co and / or Co / Mo base alloys applied by means of the coating method according to the invention have good adhesive properties on non-pretreated cylinder heads.
- valve seat rings or layers are possible that can withstand the required thermal and mechanical stress even with thin layers.
- a particular advantage of the method according to the invention lies in the fact that very thick layers can be produced, right up to quasi self-supporting components. These are comparatively high
- the method according to the invention is therefore also suitable, for example, for filling grooves, cutouts or bores in the underground or for leveling uneven surfaces.
- the sheath of the cored wire consisted of a Co / Fe alloy with an Fe content of 3% and a core made of metal powder.
- the metal powder contained 80% by weight of Mo, Si and other powder particles.
- the particle size of the powder particles used was in the range from approx. 3 to 100 ⁇ .
- the wire diameter of both wires was 3.6 mm.
- the wires were fed to a conventional wire spraying machine and melted in an arc under nitrogen.
- the deposition was carried out on a steel surface roughened by means of sandblasting with A1 2 0 3 .
- FIG. 1 The micrograph of a section of the valve seat ring thus separated can be seen in FIG. 1.
