【 摘 要 】

This article provides an assessment of the possibility of increasing the wear resistance of the alloyed surface layer for steel St3 during plasma and laser heating of the applied surface pre-coating of the mixture of CuSn/CrxCy alloys. Plasma is more suitable for reflow a pre-deposited layer of CuSn/CrxCy with a wide range of particle sizes than laser treatment. As a result, plasma coatings have a high hardness (460-700 HV) compared to laser coatings (250-500 HV). The tests carried out showed that the wear resistance increases in the following order: Steel St3
