The results of computational experiments on the formation of thermal spray WC-10Co4Cr coatings are presented. The effect of sprayed particles velocity (200-1000 m/s), temperature (1600-2500 K) and the size (15-40 microns), as well as substrate temperature (300-600 K), on the properties of coatings (porosity, roughness, adhesion) has been studied. Ranges of particle parameters have been determined, which ensure their spreading process without «splashing» and the formation of coatings with low porosity and high adhesion. A qualitative comparison of the calculation results with experimental data on high-velocity plasma spraying of WC-10Co4Cr coatings is carried out.
