Resistance of HVOF Nanostructured WC-12Co Coatings to Cavitation Erosion

Zhao Hui Zhang Yunquan Ding Zhangxiong (School of Energy & Power Engineering,WUT,Wuhan 430063)  
Nanostructured and conventional coatings are deposited by HVOF.Resistance of coatings to cavitation erosion is studied by ultrasonic vibration cavitation equipment.Cavitation holes are observed by SEM and caviation mechanisms are explored.The results show that nanostructured coatings demonstrate more excellent performance in cavitation erosion;volume loss is 1/3 less than the conventional one. The existence of nanostructured grain in the coatings is an important factor,which influences the resistance of coatings to caviation erosion.
