With the development of technology,the traditional material is difficult to meet the requirement of erosion wear.It is an effective way to prepare an erosion wear resistant coating on the surface to improve the life of the material. In this paper,the preparation methods of erosion wear resistant coatings as electroplating,thermal spraying, laser cladding,vapor deposition technology and physical vapor deposition were introduced.Moreover, the structure and property of the coatings were mentioned.Among them, this paper focus on the preparation of erosion wear resistant coating（including two and multi-component coating, multilayer composite coating）by physical vapor deposition,and the advantages of the multilayer composite coatings in erosion protection were analyzed. In the end,the development and application of erosion resistant coatings by physical vapor deposition at home and abroad were systematically introduced.
