Definitions
- the present invention relates to a method for producing a wear-resistant layer according to the preamble of patent claim 1.
- German patent DE 2208070 describes a method of this type, in which a metallic base body is provided with a thin, wear-resistant layer of up to a maximum of about 0.635 mm thick, the spraying being carried out by plasma flame spraying and the material used having a grain size of, for example, the order of magnitude. 44 / + 88 ⁇ m.
- the layer is spray-quenched when sprayed on thanks to the cooling effect of the base body, thereby creating a microstructure consisting of titanium carbide grains dispersed in a base material, the base material being formed by an austenite conversion product containing martensite. Without further heat treatment, this leads to a • relatively hard layer in which rounded titanium carbide grains are present as a result of the plasma spraying process.
- the layers that can be produced in this way are very limited in their thickness, preferably from 0.381 mm to 0.254 mm and 0.127 mm, since otherwise the structure mentioned would result in very high internal stresses.
- the small thickness corresponds to the same limited lifetime.
- the mechanical machinability is also very limited and the elasticity of the layer is extremely low due to the small grain size of the spraying material and the structure made up of the smallest lamellae.
- Wear-resistant coatings which were produced by Flamrospritzen without melting and have a high hardness due to the storage of hard materials such as carbides, silicides, borides, etc. or consist of hard alloys, show a strong sensitivity to crack formation due to the occurrence of internal stresses in the layer.
- the achievable layer thickness is very limited.
- the object of the invention is to provide a method for producing wear-resistant layers of great hardness, with which layers having a considerably longer life than those of the known layers can be produced, and which furthermore enables mechanical processing after spraying and is relatively problem-free with regard to internal stresses in the layer is.
- the layer has a lamellar structure with relatively large lamellae corresponding to the particle size, which results in greater elasticity of the layer. It should also be noted that the coefficient of expansion of the layer is very close to the coefficient of expansion of the matrix alloy.
- Adhesive layer applied 0.1 mm thick. It was a
- Powder of the composition in percent by weight, 95.0 Ni,
- a wear-resistant layer was then applied to the adhesive layer
- composition of the wettable powder in percent by weight, and the grain size we followed:
- the coated shaft was machined and brought to the finished size.
- shaft had a value of 420 Hv, after heat treatment the hardness was
- the sliding surface of 100 x 100 mm of a sliding plate of 50 mm thickness was coated in the following way. After preparing the sliding surface by blasting with corundum, the plate was preheated to 100 ° C. and then an adhesive layer - 0.1 mm thick - was applied. A commercially available adhesive layer powder (Castolin 51000) was applied by autogenous flame spraying. Subsequently, a wear-resistant layer of 1.2 mm thickness was also applied by autogenous flame spraying without subsequent melting, the composition of the wettable powder (grain size -150 / + 37 ⁇ m) in weight percent being the following:
- An axis of 40.0 mm in diameter was treated in the following manner to achieve high wear resistance.
- the axis was provided with a wear-resistant layer of 1.5 mm thickness by autogenous flame spraying under the usual working conditions, the composition of the spraying material in weight percent being chosen as follows: 33.0 TiC in a matrix alloy of 0.35 C, 2.0 Cr, 1.0 Cu, 2.0 Mo, balance Fe.
- the grain size was in the range -150 / + 37 ⁇ m.
- the surface was then machined and removed to the desired finish by grinding, the surface layer remaining 1 mm thick.
- the finished part was kept in a muffle furnace at 500 ° C. for five hours.
- the hardness of the layer before the heat treatment was 400 Hv, after the heat treatment a hardness of 680 Hv was measured.
- a wearing part with the dimensions 200 x 60 x 30 mm was coated on one of the areas of 200 x 60 mm in the following way.
- the surface to be coated was prepared by blasting with corundum, on this surface a powdery spray material of grain size -150 / + 37 ⁇ ⁇ m au ⁇ , in weight percent, 16.5 TiC with a matrix alloy of 0.5 C, 14.0 Cr , 0.5 Cu, 14.0 Mo, 3.5 W, remainder Ni applied by autogenous flame spraying without subsequent melting under normal conditions.
- the wear-resistant layer had a thickness of 2.2 mm and was then machined, the thickness of the layer being 2.0 mm was brought.
- the wear part was then kept in a muffle furnace at 450 ° C. for five hours.
- the hardness was 380 Hv before the heat treatment and rose to 550 Hv after the heat treatment.
- Example 4 The procedure of Example 4 was repeated analogously with a spray material of the composition, in percent by weight, 20.0 TiC in a matrix alloy of 0.5 C, 14.0 Cr, 0.5 Cu, 14.0 Mo, 5.0 W, Rest Co. The hardness of the heat-treated part reached 530 Hv.

Abstract
Une matière frittée, contenant des particules agglomérées ou des particules alliées contenant 10-50% en poids de carbure de titane et un alliage de fer et/ou de nickel ou un alliage de cobalt, est déposée par pulvérisation à la flamme sur une épaisseur d'au moins 1 mm. Elle est soumise ensuite à un traitement thermique à une température comprise entre 400 et 650°C après un éventuel façonnage mécanique. Le procédé permet la fabrication de couches résistant à l'usure, de dureté élevée et d'épaisseur relativement grande, assurant une longue durée, évitant les tensions intérieures et donnant la possibilité d'un façonnage mécanique après la pulvérisation.A sintered material, containing agglomerated particles or alloyed particles containing 10-50% by weight of titanium carbide and an iron and / or nickel alloy or a cobalt alloy, is deposited by flame spraying on a thickness d '' at least 1 mm. It is then subjected to a heat treatment at a temperature between 400 and 650 ° C after possible mechanical shaping. The process allows the manufacture of wear-resistant layers, of high hardness and of relatively large thickness, ensuring a long duration, avoiding internal tensions and giving the possibility of mechanical shaping after spraying.
