In this work, metal ion implantation was employed to improve the mechanical properties of Al2O3/polytetrafluoroethylene (Al2O3/PTFE). Four metal ions (Al, Cr, Ni, and Ag) were selected as the implantation source, respectively, and the implantation process was optimized by SRIM method. Optimization results revealed that, among these four metal ions, implantation of Al ions exhibited the best modification for Al2O3/PTFE composite layer, when the particle distribution section, distribution range and energy exchange were concerned. Al ion implantation could minimize the damage of carbon skeleton and lamellar structure of Al2O3/PTFE substrate, which kept strong scattering of Al ions and obtained the thick and uniform coating on the surface of Al2O3/PTFE substrate. The uniformity of Al2O3/PTFE layer was improved with the increase in Al ions implantation dosage and the best dosage of Al ions was regarded as 1×1016 ions/cm3 with the implantation energy of 20KeV. After implantation modification, the mechanical properties of Al2O3/PTFE layer were obviously improved. The hardness (H) of samples was detected to be 0.65GPa and elastic modulus (E) 2.2 GPa, with a higher H/E value of 0.295, which was 10 times higher than original PTFE.
