US 2018/0023016 A1 · AMORPHOUS HYDROCARBON BASED FILM, AND SLIDING MEMBER AND SLIDING SYSTEM PROVIDED WITH SAID FILM

Abstract

A low-friction coating includes: an aliphatic hydrocarbon group showing a peak in a region of 2,900 cm−1 to 3000 cm−1 in an infrared absorption spectrum; a carbonyl group showing a peak in a region of 1,650 cm−1 to 1,800 cm−1 in an infrared absorption spectrum; an aromatic component (C7H7+) showing a peak at mass 91.1 in a positive ion spectrum obtained by TOF-SIMS; and a condensed ring based component (C9H7+) showing a peak at mass 115.2 in the positive ion spectrum obtained by TOF-SIMS.
