DIAMOND SURFACE TREATMENT Russian patent published in 2016 - IPC C30B33/00 C30B33/02 C30B29/04 C01B31/06 H01L21/302 

FIELD: electronics.

SUBSTANCE: invention relates to methods of processing diamond surface for its use in microwave electronic equipment. Method involves arrangement in one plane of initial surface of diamond and metal surface of steel, providing direct contact of said surfaces, thermal treatment of initial diamond surface at given depth to preset final diamond surface, wherein providing of heating of said surfaces in inert medium, at specified speed, near temperature of formation of eutectic alloy of iron-carbon, holding at this temperature and natural cooling, wherein metal surface of steel are taken with carbon content of 3.9-4.1 wt.%, with surface finish class on side of contact of said surfaces of not less than 14, contact of said surfaces is performed over entire surface or locally according to specified end surface of diamond, heating said surfaces is performed at 1090-1135 °C, during heating of primary diamond surface and metal surface of steel and holding their displacement in contact plane is performed relative to each other in cycles, wherein holding at said temperature is performed during time (t_hold., s), movement of initial surface of diamond and metal surface of steel relative to each other is carried out at rate of displacement (v_disp, mm/s) and amount of cycles of displacement (n), which values are determined from corresponding expressions.

EFFECT: technical result is increase of quality of treatment due to reduced surface roughness of diamond.
