Abstract
A coating includes a thin film which is intended to protect a corrodible part against corrosion and, to some extent, against wear and friction. The coating essentially includes a composition containing silicon, carbon, hydrogen and nitrogen such that: the atomic hydrogen concentration, measured using the ERDA technique, is 20 ±5 atoms %; the atomic silicon concentration, measured using the Rutherford backscattering (RBS) technique, is between 15 and 28 atoms %; the ratio of the atomic concentrations of nitrogen and carbon (N/C) is greater than 0.9; and the hardness of the material is less than or equal to 2100 daN/mm2.
