Diffusion between Ti6Al4V and Cemented Carbide with Different Compositions

Titanium alloys have been widely used in the aerospace industry because of their excellent properties, such as light weights, high strengths, and corrosion resistance. In this research, element diffusion between tungsten–cobalt cemented carbide Ti6Al4V was analyzed using thermodynamic solution theory. First, it observed that W, Co, Ti elements diffused under a temperature pressure. Then, by analyzing different elements, found amount depth W Co from increased with increases content WC grain size, while decreased decreases size. It also holding time. Finally, milling experiment conducted, an analysis cutting-edge section existence substrate, which proved occurrence phenomenon. No during chip analysis, but there. The higher hardness grains caused to etch onto surface experiment.
