Abstract-To overcome the the drawbacks of poor wear resisitance of titanium and its alloys, so far many efforts have been made to improve wear resistance and some techniques have been developed. Theses techniques can be classified into two categories: surface coating and surface cladding. Surface coatings generally include BN film, diamond-like carbon films and TiN films. These surface thin layers very significantly enhance the tribological properties although the some disadvantages still exist such as the small thickness, unstable composition, and poor adherence to substrate. The most applicable achievement is surface cladding. Surface cladding overcomes the drawbacks of surface coating. Not only the thickness of the surface composite layers can be controlled but the composition of the layer can be flexiblely choiced as well. Compositions of clad layer are diversified. The bonding strength between the surface clad layer and the substrate is very high. Among those, the laser beam cladding is a cutting edge and a promising method.
