Abstract
Laser cladding is an effective way to improve the surface hardness and wear resistance of titanium alloy. The powder materials and laser cladding process parameters have great influence on the properties of the wear resistant coating. In order to reduce the common defects including the cracks and pores of the coating, titanium alloy powder and self-melting alloy powder are selected to ensure the good adhesion between titanium alloy and wear resistant coating. In addition, the strengthening phase and self-lubricating phase were added to the laser cladding powder material to improve the micro hardness and reduce the friction coefficient, which bring in the improvement of the wear resistance of the coating. In the present work, the selection principle and application effect of powder materials for wear-resistant coatings are reviewed. the research status of the influence of laser technological parameters on coating properties is discussed. Meanwhile, the methods to reduce the defect of wear resistance coating by laser cladding are proposed.
