In this investigation, tool grade P20 WC was coated using the Chemical Vapor Deposition (CVD) method. The specimen was coated uniformly with Al2O3 of 1.5 µm thickness over an additional coating of TiC. TiC coating thickness varied at four different thicknesses: 3 µm, 6 µm, 9 µm, and 12 µm. The investigation was conducted with a turning operation in high-strength steel at higher cutting speed. Using SEM and X-ray, the progress of crater wear was carefully observed.
