A study of the inhibitive effect of Mo on the temper softening of bearing surfaces caused by ion implantation

Bearing steels are very sensitive to temper. The actual strengthening effect of ion implantation is dependent on competition between the adulterated strengthening and implantation tempering on the bearing surface. In this study, the adulterated strengthening and implantation tempering of large dose...

Description
Summary:Bearing steels are very sensitive to temper. The actual strengthening effect of ion implantation is dependent on competition between the adulterated strengthening and implantation tempering on the bearing surface. In this study, the adulterated strengthening and implantation tempering of large dose N + implantation and the inhibitive effect of Mo on implantation tempering were investigated using Auger electron spectroscopy, X-ray photoelectron spectroscopy, Rutherford backscattering spectrometry, X-ray diffraction, friction and wear testing, contact fatigue testing, etc. The results indicate that overlapping implantation of Mo + and N + is an effective method for strengthening the bearing surface.
