The results of experimental research on modifying the surface layer of 316L steel by duplex treatment are presented. The latter includes ion-plasma treatment in a nitrogen atmosphere with subsequent plasma-enhanced chemical vapor deposition of hydrocarbon films doped with silicon and oxygen (a-C:H:SiOx). Mechanical properties of steel surface (hardness, modulus of elasticity, plasticity index, plastic deformation resistance) were determined by the nanoindentation method, and adhesion of the films was evaluated by a scratch test. It was found that the greatest improvement in the mechanical properties of the film-substrate system occurs after the deposition of a-C:H:SiOx film on a surface previously hardened in a nitrogen plasma.
