%X This paper investigated the effects of wear paramaters , such as sliding speed and load , on the wear properties of Fe-based nanostructured coating . A series of Fe - based nanostructured coatings were prepared by using wire arc spray. The microstructure of the coating was characterized by SEM , EDAX , XRD and TEM . The mechanical properties of the coating were measure d by nanoindention . The wear tests of coatings were conducted on a MM2OO wear tester . The microstructure of the coating consisted of amorphous phase and nanocrystalline ( Fc , Cr ) Phase . The nano- grains with an average size of 46 nm were homogenously dispersed in an amorphous phase matrix . The coating was nearly full- densed with a porosity of 1. 7 % and high hardness . With the increase of sliding speed and load , the wear mass of the coating increased . The nanostructured coating had excellent wear resistance , i?e . the nanostructured coating was 2 . 6 times as high as that of the 3Crl3 coating . The failure mechanism of the coatings was brittle fracture
