Comparison Study of Wear Properties Between Laser Quenching and Flame Quenching of 42CrMo Steel
In the course of service, the power fittings often fail prematurely because of the complex service environment. In order to further improve the service life of the power fittings, in this paper, laser quenching and flame quenching were used to strengthen the surface of the samples. The microstructure and hardness of surface hardening layer under different treatment methods were studied. The wear resistance was tested by a friction and wear tester, and the surface wear morphology and wear mechanism were analyzed. Results show that after laser quenching and flame quenching, the wear resistance of the original samples is improved in different degrees. The weight loss after laser quenching is reduced by 80.60%, and the wear degree is slight. The weight loss after flame quenching is reduced by 66.24%, and the wear mechanism is abrasive wear. The wear mechanism of untreated samples is dominated by adhesion wear.
