Abstract

order to explore the effective ways and methods of improving the tribological properties of polytetrafluoroethylene (PTFE), energy transfer were optimized with using the SRIM software. when different kinds of metal ion sources (Al, Gr, Ni, Ag), implantation energies (20, 25, 30, 40 KeV) , and different doses of (1×10、1×10、 5×10、 1×10ions/cm)were employed, Stimulation and optimization design in this paper mainly focused on one aspect of the four implanted metal particles: energy transfer. adjust implantation energy in four different values, Research showed , Wear resistance of PTFE is improved better by ion implantation. When four different kinds of ions (Al, Cr, Ni, and Ag) are implanted to PTFE, Al ions show the best implantation effect among the four kinds of metal ions.when implantation energy was 20KeV, it can lead to a best modification effect and can also maintain a sufficient implantation depth and a smaller damage. When implant Al ions with the same implantation energy, the nano-composite film can be more homogeneous and the performance can be more consistent with the increase of the
