The single-pass, transfer wear of LDPE, PVC, and PCTFE was studied as a function of the roughness of the steel counterface, and the presence or absence of a polymeric coating. A 50 nm thick film of poly(chloro-p-xylylene) was formed on the steel in a pyrolytic-vapor-deposition process. The results showed that LDPE had lower friction and wear on the coated surface than on the uncoated surface. There was no significant difference in wear or friction as a function of surface coating for PVC and PCTFE. The results were explained by considering the deformation characteristics of the polymeric coating and the three polymer sliders and the modification of the topography by the polymeric coating.
