Research Status of HardCoatings against Sand Blasting Erosion Wear

In order to prolong the service life of parts and reduce the loss of materials and energy, hard coatings are applied to sandblasting erosion wear environments. This paper introduces the harm of sandblasting erosion wear and the application of hard coatings against sandblasting erosion wear. The influence of mechanical properties for hard coatings, matrix properties, particle properties and particle sandblasting process parameters on sand blasting erosion wear were reviewed, respectively. The research of dynamic simulation and impact test of sandblasting erosion is summarized. It is pointed out that the hardness and toughness of coatings and the matching of substrate and coating properties are beneficial to improve the resistance of coatings to sand blasting erosion wear. The prospect of the impact wear mechanism models of various hard coatings against sandblasting is expected by combining digital simulation with experimental verification
