MULTI-LAYER METALLISED COATING OF DIAMOND OR DIAMOND-CONTAINING MATERIALS AND ITEMS OUT OF THEM AND PROCEDURE FOR ITS APPLICATION

摘要

1. Metallization of the diamond and / or diamond-bearing materials and products are based on metal carbide, characterized in that the metallization is a straight metal layer sequence titanium carbide - titanium or iron - nickel total thickness of 0.3-0.5 microns at a ratio of components 55:45 vol.%, respectively, and the molybdenum or tungsten thickness of 1.0-1.3 microns. ! 2. Metallization of the diamond and / or diamond-bearing materials and products thereof according to claim 1, characterized in that the layer of titanium - titanium or iron - nickel and molybdenum or tungsten layer may be formed together in any formulation. ! 3. The method of manufacturing a metallization diamond and / or diamond-bearing materials and products made of them consists in processing the surface of diamond and / or diamond-containing material in a melt of alkali at a temperature of 250-300 ° C, followed by its activation by heating at a temperature of 750-800 ° C. for 1-1.5 hours in the air and subsequent deposition on said surface metallization based metal carbide in vacuo, and wherein said surface is at normal temperature, characterized in that the deposition of metallization uschestvlyayut arc plasma method stages with two targets cathodes in a single process cycle, wherein the first phase - a first target-cathode sputtered layer of titanium - titanium or iron - nickel total thickness of 0.3-0.5 microns at a ratio of components 55 .: 45 vol%, respectively, at the second stage - a second target-cathode layer of molybdenum or tungsten 1.0-1.3 microns thick at a current targets on cathodes, and 120-130 and 200-230 for 80-100 and 250 -280, respectively. ! 4. The method of manufacturing a metallization
