To enhance the adhesion of diamond film on WC-Co substrate, interface of TiC and SiC by sputtering technique were introduced between them. The film structure and surface morphology have been checked by x-ray diffraction, Raman spectroscopy and SEM. The adhesion between both coating and substrate have been evaluated by cutting test. In addition, the vertical tensile test has been carried out to measure the adhesion strength, which indicated that the introduce of the interface layer played important effect for improvement of the film adhesion strength.
