Abstract
The effects of proton implantation on the tribological behavior of MoS2/PES-C composites were studied. The structural changes of the composites caused by the proton implantation were studied by using infrared spectra and X-ray photoelectron spectroscopy (XPS). The results show that part of PES-C degrades after proton implantation, and a carbon-rich structure forms on the surface of the composites, whereas there are no obvious chemical changes for MoS2 during the implantation process. The friction and wear tests reveal that the wear-resist ance of the composites could be improved by proton implantation. Especially when the dose reaches 1.25 × 1016 ions/cm2, its friction coefficient and wear rate decrease simultaneously. The wear mechanism changes from adhesive wear and plastic deformation for the un-implanted composites to fatigue wear for the implanted ones.
