Abstract:Fe-based amorphous alloy is widely applied in the fields of petroleum, coal, steel and ship etc. because of its excellent wear and corrosion resistance. Fe-based amorphous alloy coatings are prepared by high velocity oxygen fuel thermal spraying on 316 stainless steel substrate in this paper. Fe-based amorphous alloy coatings’ grinding performance, the grinded surface’ wear resistance and corrosion resistance are explored separately. The results show that the grinding depth has the most impact on surface roughness and corrosion resistance of the coatings’ surface, feed speed takes the second place; the feed speed has the most impact on wear resistance of the coatings’ surface, grinding depth takes the second place; the grinding speeding has the least impact on surface roughness, wear resistance and corrosion resistance of the coatings’ surface. Finally, the best grinding parameters combinations are selected according to the different characteristics of coatings.
