Abstract: The XRD spectrum of titanium-coated diamond showed the existence of titanium carbide on the interface between diamond and its titanium coating. The diffusions between titanium coating and metal matrices were studied by SEM. The SEM photographs revealed that titanium can interdiffuse with nickel, cobalt, copper,iron and copper-based alloy to a great extent to lead to the disappearance of pure titanium layer and the formation of titanium diffusion layer. The results from transverse-rupture strength test showed that titanium coating on diamond  improved the bonding strength between diamond and metal matrices by 3.2% for Co-based segment and 4.1% for Cu-10Sn based segment respectively.

 

Key words:  interdiffusion; transverserupture strength; titaniumcoated diamond
