Abstract
An amorphous thin film as a solid lubricant having a low coefficient of friction. It is composed of silicon (Si), oxygen (O), carbon (C), and hydrogen (H), and has a composition defined by the formula: Si.sub.x (O.sub.m, C.sub.n, H.sub.l-m-n).sub.1-x where, x=0.03-0.02, m=0.05-0.5, =0.1-0.9, and 0.6.ltoreq.m+n.ltoreq.0.95. This thin film exhibits extremely low friction stably from the beginning of sliding. It has superior wear resistance owing to its high hardness.
