Nanomechanical property analysis of fast atom beam (FAB) treated ultrahigh molecular weight polyethylene

Research output: Contribution to journalArticle

Abstract

Thin, modified surface layers were created on ultrahigh molecular weight polyethylene (UHMWPE) by treating them with low-energy (∼1 keV) fast atom beams (FAB) of argon, helium, hydrogen and nitrogen. Nanomechanical properties including multipass wear characteristics, dry friction coefficient and topography (roughness) were measured on these modified surfaces. As a result of FAB treatment, the volume loss - calculated from the geometrical characteristics of the Rockwell head and from the depth of the permanent scratch track - could decrease by more than 1 order of magnitude, implying a similar increase in the wear resistance. FAB treatment increased also the dry friction coefficient, while the mean roughness was not altered significantly.
