This research is a study on ultrahigh molecular weight polyethylene (UHMWPEGUR 1020) implanted with 100–300keV ions in order to modify its surface chemical, physical, and mechanical properties. Boron, nitrogen, argon, and xenon ions, at doses between 1012 and 1016/cm2, have been employed to irradiate polyethylene in high vacuum. Roughness, hardness, wear resistance, and wettability represent some of the superficial properties that are modified by the ion irradiation versus dose. Results highlight the modification depth and surface property dependence on the ion specie and dose. The material wear resistance after the ion implantation has been improved up to about 70%.

Abstract

This research is a study on ultrahigh molecular weight polyethylene (UHMWPEGUR 1020) implanted with 100–300keV ions in order to modify its surface chemical, physical, and mechanical properties. Boron, nitrogen, argon, and xenon ions, at doses between 1012 and 1016/cm2, have been employed to irradiate polyethylene in high vacuum. Roughness, hardness, wear resistance, and wettability represent some of the superficial properties that are modified by the ion irradiation versus dose. Results highlight the modification depth and surface property dependence on the ion specie and dose. The material wear resistance after the ion implantation has been improved up to about 70%.
