Adhesion Strength of HFCVD Diamond Coating on WC Substrate Seeded with Diamond and Different Ratios of SiC Powders

The effect of seeding using different mixtures of diamond and silicon carbide (SiC) powders on the adhesion strength of hot-filament chemical vapor deposition (HFCVD) diamond coating on WC-6% Co substrates was studied. Diamond powders with the average grain size of 0.5 μm mixed with various concentr...
