Effect of Laser Quenching on the Microstructure and the Abrasive Wear Resistance of 30KhGSA Steel

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) CO 2 laser are presented. Fine martensite forms in the hardened zone and th...

Zusammenfassung:	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) CO 2 laser are presented. Fine martensite forms in the hardened zone and the steel has a high hardness and abrasion resistance.
