| Abstract | Chromium thin films were prepd. on glass substrate via a two-step thermal deposition and their structural, chem. and tribol. properties were detd. The x-ray diffraction pattern of the two-step thermally deposited chromium film showed the presence of well-defined body-centered cubic Cr metal structure with a prominent (1 1 0) plane. XPS depth profile showed a presence of ∼2% of oxygen in the film within the first five etching cycles showing oxygen incorporation. Dry sliding wear expts. at temps. ranging from 20 to 200° were conducted. The thin films were worn with either 100Cr6 or 440C bearing balls using a ball-on-disk sliding configuration at a contact load of 1 N. Friction coeff. and coating wear rates were measured and wear tracks were analyzed using optical microscopy, SEM and energy-dispersive x-ray spectroscopy. Thin films exhibited low wear rates at room temp. and an unexpected wear behavior at the elevated temps. Only the first half of the metallic chromium film was worn out after ∼18 m of dry sliding at room temp., whereas increase in temp. resulted in a decrease in wear resistance of the film.
