Comparison on wear resistance of nanostructured bainitic bearing steel with and without residual cementite
文献摘要：
The sliding wear property of high-carbon nanostructured bainitic bearing steel with the equal initial hardness and different microstructures was investigated,and the reasons for the difference of wear resistance between the cementite-bearing(CB)and cementite-free(CF)specimens were analyzed.The results show that CF specimens have lower mass loss and surface roughness and shallower wear depth than CB specimens during wear process.Compared with CB specimen,CF specimen presents superior wear resistance.This is due to two reasons:(1)a lot of retained austenite in CF specimen is easy to produce TRIP effect and be transformed into martensite during wear process,which notably increased the surface hardness of worn specimen;(2)there is a nondestructive oxide layer in the surface of cementite-free worn specimen,which can protect the surface of worn specimen from destruction.Under the combined effect of retained austenite and oxide layer,the loss of matrix is reduced.Thus,CF specimen exhibits high wear resistance.It reveals that the wear mechanism of high-carbon nanostructured bainitic bearing steel with different microstructures can provide a reference for improving the wear resistance in high-carbon nanostructured bainitic bearing steel in future.
