A Study on the Friction and Wear Characteristic of TiAlN and CrAlN Coating on the SKD61 Extrusion Mold Steel for 6xxx Aluminum Alloy Kim, Min-Suck; Kho, Jin-Hyun; Kim, Sang-Ho;
In this research, the friction and wear characteristic behaviors of coating materials of TiAlN and CrAlN were investigated. The wear test was conducted in air and un-lubricated state using the reciprocating friction wear tester. Temperature were 50 and , and load were 3, 7, and 11 kgf for tests. By comparing the coefficient of friction and observing the wear microstructure, the friction and wear characteristic behaviors of TiAlN and CrAlN coating layers on SKD61 were investigated. The coefficient of friction of CrAlN coating was lower than that of TiAlN at all conditions. Therefore, CrAlN was suggested to be more advantageous coating than TiAlN for the extrusion mold of aluminum.
