The purpose of this study is to show the friction and wear characteristic behaviors of TiN and CrN coated SKD61 which is applied to Al 6xxx extrusion mold material. The friction and wear characteristic behaviors of both coating layers were investigated by the reciprocating friction wear tester under atmospheric pressure and un-lubricated state. The processing parameters in this study were temperature (50 and 120℃) and load (3, 5, and 11 kgf). This study was carried out while comparing the coefficient of friction and microstructure of TiN and CrN coating layers on SKD61. The coefficient of friction of CrN became lower than that of TiN at all conditions. Therefore, CrN was suggested to be more advantageous than TiN for extrusion mold.
