Process of depositing diamond coating on diamond-impregnated cemented carbide
摘要
Abstract
To enhance the bonding strength between diamond coating and matrix,chemical vapor deposition was used to deposit diamond coatings on ordinary and diamond-impregnated cemented carbides,separately.SEM,Raman and indentation tests were used to analyze and compare the coatings.Results show that both homoepitaxial and heteroepitaxial growths of diamond coating could be found on the diamond-impregnated cemented carbide substrate,and that the coating deposited on diamond-impregnated cemented carbide substrate performs high diamond nucleation rate,uniform crystal size,and flat coating surface.It is also found that the bonding strength between diamond coating and diamond-impregnated cemented carbide is higher than that between coating and ordinary substrate,which will greatly expand the application of diamond coating.关键词
