Tribological properties of DLC films on Polymers

Abstract

Our study is to research for tribological properties of diamond-like carbon (DLC) films on various polymers. DLC film is one kind of thin hard films. Among the tribological properties of the film, its most remarkable features are on low-friction coefficient and anti-wear. This report deals with the deposition of DLC films on various polymer substrates in vacuum by magnetron radio frequency (RF) sputtering method with using argon plasma and graphite target. Polyamide6(PA6), polyphenylenesulfide(PPS), polyetheretherketone(PEEK) were used as substrate. The properties of friction and wear are investigated using a ball-on-disk weartesting machine. The friction coefficient of DLC coated specimen is lower than that untreated specimen.
