Durability of working bodies of soil-cultivating machines strengthened by composite electrolytic coatings (CEC)

The task of this work is to find the optimal ratio between size particles silicon carbide and their volumetric content in nickel matrix provide maximum characteristics strength wear resistance working bodies soil-processing machines. article investigates processes forming complex electrolytic coatings (CEC) on a basis with filler various sizes (SIC). It has been established that formation sicle SiC5 carried out vertical, all other horizontal cathode. SICnano reaches about 10%, SiC100 – 46 %. Cap particle 28/20 50/40 μm allow you get most wear-resistant coatings. In case, coating have higher resistance, but are more technological when they formed. significant effect tribological CEP, namely friction coefficient. highest smallest coefficients characterized by having as fractions μm. Tribological studies show promise efficiency CEP increase soil-cultivating
