Preparation and Tribological Properties of TiN/Ti Film on Ti6Al4V Surface
TiN/Ti film was deposited by DC magnetron sputtering on Ti6Al4V surface.The surface and cross-section morphologies,composition and phase structure of TiN/Ti film were characterized by FESEM,GDOES and XRD,respectively.The adhesion between substrate and film was analyzed by scratch test.The wear resistance of TiN/Ti film was investigated by ball on disc wear test and white light interference.The results indicate that TiN/Ti films exhibit smooth surface and dense structure columnar crystal with cascade-like glacier feature,which can show well bonding strength and improvement of wear resistance.
