Fhase forming and structural feature twu-layer coating «titanium/nichrome» on artificial polycrystalline diamonds

Abstract

The phase forming and the structural features of two-layer coating «titan/nichrome» on the surface of artificial polycrystalline diamonds ASB-4 are examined. The film was deposited by method of ion-plasma vacuum 10-2 Pа evaporation. The X-ray-phase film analysis indicated that at the surface the phases Ni4Ti3, Cr7Ni3, Cr2Ti, Cr0,875Ti0,125, NiTi and others are organized. In the films it is seen the fomation of spherical phases, conceivably Cr0,075Ti0,125. On diamond films, obtained by recuperation, the structural patterns are seen which are typical for Zn.
