摘要

The effects of deep-nitriding and following shot peening on microhardness, rolling contact fatigue property of 32Cr3MoVA steel were investigated and Scanning Electron Microscope (SEM) was employed to evaluate the failure surface of rolling contact fatigue specimens. The fatigue results indicate that the depth of deep-nitrided layer is about 0.75 mm and following shot peening can improve the rolling contact fatigue life. The SEM test shows that the area of failure for nitrided and following shot-peened specimens is smaller and the depth of pit is lower compared with nitrided specimens.
