Abstract
A diamond-like hard carbon film is formed on a substrate by impinging particles of carbon onto a surface of the substrate, bombarding the surface of the substrate with accelerated particles of inert gas or particles of carbon together with hydrogen in a direction not more than 10 degrees out of parallel to the surface so that the particles of carbon aggregate on the surface, at room temperature.
