Different substrate surface pretreatments have been used to improve the adhesion of CVD diamond coatings on WC-Co substrates. In this paper, we report the results of our experiments using a pretreatment method based on two-step chemical etching: one in Murakami solution and another in aqua regia. A systematic study was performed to evaluate the influence of the pretreatment on the composition and morphology of the WC-Co substrate. Furthermore, the effect of diamond nanoparticle seeding on the morphology and roughness of the substrate was also analyzed. After these studies, diamond coating was deposited on seeded WC-Co substrate by hot-filament CVD. The characterization of the CVD diamond coating was performed by Raman spectroscopy, FEG-SEM and AFM. Rockwell C indentation test was used to evaluate the adhesion between the CVD diamond coating and the WC-Co substrate.
