摘要：

The results of microstructural studies, the microhardness distribution, and the estimation of abrasive wear resistance of structural 30KhGSA steel samples hardened during continuous irradiation with a multichannel (48 beams) CO2 laser are presented. Fine martensite forms in the hardened zone and the steel has a high hardness and abrasion resistance.
