摘要
A chromium nitride (CrN) coating was deposited on YT14 cemented carbide using a cathodic arc ion plating (CAIP). The high temperature friction and wear of the obtained coating were investigated using a wear test. The results show that the Cr and N form the atom-rich zones in the coating. The average coefficient of friction (COF) of CrN coatings at 300 degrees C, 400 degrees C, and 500 degrees C is 0.50, 0.62, and 0.43, respectively. The wear mechanism of CrN coating at 300 degrees C and 400 degrees C is abrasive wear, and that at 500 degrees C is abrasive wear, accompanied by slight oxidation wear.
