The article presents the results of a study on increasing the wear resistance of the cutting part of thermofriction tools by surfacing. The main factors that have a prevailing influence on the increase in the consumption of metal-cutting tools in the current conditions of machine-building industries of the Republic of Kazakhstan are revealed. The analysis of the methods of traditional thermo-frictional treatment and methods of applying coatings to increase the wear resistance of the surface of steels. Analysis of existing surfacing materials showed that STOODY M7-G, STOODY 102-G and OK TUBRODUR 58 O/G M surfacing materials have high hardness, wear resistance and temperature resistance. The technique for studying the hardness of the deposited layers is based on experimental and metallographic research methods. Surfacing of 12 samples of mild structural steel St3 was carried out. One-layer, two-layer and three-layer surfacing were applied on the surface of the samples. Surfacing of 12 samples of mild structural steel St3 was performed. One-layer, two-layer and three-layer surfacing were applied on the surface of the samples. The results of the study of the hardness of the deposited layers showed that the surfacing materials retain the original hardness during two-layer surfacing. In this case, the thickness of the first and second layers should be 4 and 2 mm, respectively.
