ABSTRACT:
A substrate is treated for forming a thin film on the surface of the substrate to obtain a hard layer adhering to the substrate surface. For this purpose the substrate is placed in a metal vapor atmosphere and simultaneously bombarded by metal or nonmetal ions which are implanted into the substrate while the metal vapor atmosphere is also being ionized.
