Study on Fe-based amorphous coating prepared by arc spraying

Bin-you Fu, Dingyong He, Jiang Jian-min, Xiaoyan Li

Abstract

Fe-based amorphous alloy coatings were prepared on mild carbon steel substrate by arc spraying.Microstructure and properties of the coatings were investigated by XRD,SEM,TEM and micro-hardness test.Wear resistance of the coatings were eximined by wet sand/rubber wheel abrasive wear tester.The experiment results show that the coating has laminated microstructure with a little micropores and oxides.The coating has high hardness and excellent wear resistance,and its relatively wear resistance is 15.2 times of mild carbon steel in the same experimental condition.
