FIELD: technological processes.

SUBSTANCE: invention may be used for creation of different single crystal processing tools, medical tools, for creation of electric contacts with metal on the surface of semiconductor and other diamonds. Preliminarily surface of diamond single crystal is polished to 5^th class of roughness (according to state standard GOST 2789-73) and degreased. Degreased surface of diamond single crystal is coated with intermediate layer with thickness of 0.05÷0.4 mm from mixture of nanodispersed powders of ferric oxides with size of particles of 20÷40 nm and fullerene C₆₀. Ratio of ferrous oxides content to fullerene C₆₀ makes 10-50:90-50 wt %. Then place of contact is exposed to pressure of 2.0÷5.0 GPa and simultaneously to shift effect by rotation at the angle of 100÷1000 degrees.

EFFECT: higher strength and quality of diamond single crystal binding to metal.
