| Abstract: | Polyethylene terephthalane (PET) has been modified with Ti, Ag, Si, and C ions from a metal vapor arc source (MEVVA). The results show that the surface hardness, modulus and wear resistance could be increased. The corrosion resistance was improved noticeably. According to medical requirements: the resistance in wear and corrosion of implant materials and biocompatibility are very good. The way of enhanced resistance in wear and corrosion of polymer materials was studied, and the biocompatibility of polymer was improved by ion implantation. Finally, the modification mechanism was discussed. |
