Аннотация
The results of metallographic studies and laboratory comparative adhesion strength tests of the coating with the base and abrasive wear by Brinell–Havorth method of weld powder coatings on nickel base with a width of weld layer of 20–80 mm and a height of 3–9 mm in one pass and samples of 40Kh steel have been presented. The adhesion strength of coating with hardness of 38–42 HRC was 400–480 MPa. It has been revealed that, at a hardness of the weld layer of 58–61 HRC, the wear resistance of coatings is higher than that of 40Kh steel in normalized and the improved state by 10 and 4.6 times respectively.
