Abstract

Silicone oil vapor deposition and Ar+ ion irradiation can form an adhesive carbonaceous film on a steel substrate. The friction coefficient μ of the coated substrate is found to be very low for sliding against a steel ball both in air (μ ∼ 0.04) and in N2 gas (μ < 0.02). The duration of the low friction state is comparatively long and is 5 × 103–1.5 × 104 cycles for a film 0.15 μm thick. X-ray photoemission spectroscopy, infrared reflection spectra, and Raman measurements indicate that the film mainly consists of amorphous carbon containing Si and O.
