Abstract

The structure, hardness and tribological characteristics of the electrospark coating based on high nitrogen structural steel of the Fe–C–Cr–Mn–Mo–Ni–V alloying system were studied. It was found that the maximum thickness of the coating based on steel is 34,5 μm. Samples with a single-layer coating of 18 μm thick have the best wear resistance. Application of the coating helps to increase the wear resistance of 30KhGSN2A steel by more than 3 times.
