Abstract

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.
