The solid-particle erosion resistance of Ti-6Al-4V can be improved significantly by applying a chemical-vapor-deposited diamond coating under conditions where physical-vapor-deposited coated substrates fail. In particular, diamond coatings grown with relatively high methane concentrations (4-10%) in the process gas atmosphere exhibit superior performance. The reason for this behavior is a higher in-plane strength of these coatings due to growth defects like twin formation and secondary nucleation.
