Abstract
Using THT07-135 high temperature machinery to analysis tribological properties of high velocity flame spraying (HVFS) Fe-Al/Cr3C2 composite coating, wear scar images and composites in different region were analyzed by SEM and EDS, existing state of reinforcement were analyzed by TEM, The results show that coating has relatively better friction and wear rcsistance properties, friction coefficient changes little with the increasing of wear distance. Wear resistance performance of coating differs from normal metallic materiats. With incrcasing in temperature, it increases firstly and reaches a peak at 550℃, then decreases later. Hamper effect of reinforcements in costing makes the wear resistance performance of coating better. The predominant wear mechanism of the Fe-Al/Cr3C2 coatings is exfoliation. The mainly reason why the high-temperature wear resistance properties of FeAl/Cr3C2 composite coating differs from normal metallic materials is the yield strength of basic phase Fe-Al intermetallics in coating changing with high-temperature is unusually,关键词
