COATED DIAMOND, METHOD FOR PREPARING THE SAME AND COMPOSITE MATERIAL COMPRISING THE SAME

摘要

A coated diamond comprising diamond (1) and a SiC film (2) coating the diamond (1), wherein the SiC consists substantially of beta -SiC and has a value of I(220)/I(111) of 0.38 to 0.55, which value is a ratio of the peak intensity I(220) of a face index (220) to the peak intensity I(111) of a face index (111). The coated diamond has a close coating and is excellent in adhesiveness between diamond and the coating, and thus can be used for preparing a composite material which exhibits excellent properties inherent in diamond more faithfully.
