Abstract In order to improve the rolling contact fatigue (RCF) performance of GCr15 bearing steel, four plasma quenching experiments with different scanning speeds (350 mm/min, 550 mm/min, 750 mm/min, 950 mm/min) were carried out on the surface of GCr15 bearing steel by laminar plasma quenching (LPQ). The MJP-30 rolling contact fatigue testing machine was used to conduct RCF tests on the samples before and after the treatment. The laser confocal microscope (VK-9710), super depth of field microscope (UDM, VHX-1000C, Japan) and scanning electron microscope were used to analyze the microstructure, composition and microscopic damage morphology of the samples. The hardness of the samples was tested, and the fatigue propagation mechanism was analyzed. The results show that due to the rapid cooling rate and heating rate of LPQ, hardening zone was formed on the surface of the sample, and thus fine cryptocrystalline martensite structure was formed, which increased the surface hardness. The hardening layer thickness affects the RCF propagation mechanism. The deeper the hardening layer thickness is, the longer the fatigue life is. LPQ can increase the RCF life by 64%.
