Effect of heat treatment on the corrosion resistance of Ni-based and Cu-based amorphous alloy coatings

Effect of heat treatment on the microstructure and mechanical properties of Fe-based amorphous coatings

“…The heat treatment of amorphous coatings leads to the precipitation of sub-micrometric crystals [18], which definitely enhances the mechanical properties of coatings, such as the microhardness, fracture toughness and wear resistance [19][20][21][22]. Yoo et al [23] have found that the amorphous structured coatings exhibit a superior corrosion resistance to the crystallized coatings with high polarization resistance, and the The present study aimed at investigating the effect of post heat treatment on the microstructure and mechanical properties of arc sprayed Fe-based amorphous coatings.…”

The effect of high-velocity oxy-fuel spraying parameters on microstructure, corrosion and wear resistance of Fe-based metallic glass coatings

“…On the other hand, although coating H3 has a lower porosity than coating H2, the former prepared at the highest spraying power contains a certain amount of crystalline phases (see Fig. 3b) that destroy the homogeneity of the passivation film [24,25], and hence coating H3 exhibits worse corrosion resistance than coating H2.…”

Effect of annealing on the microstructure, microhardness, and corrosion resistance of Ni 62 Nb 33 Zr 5 metallic glass and its composites

“…Recently, Ni-based metallic glasses have been attracted considerable interest due to their high thermal stability [1], high strength [2] and distinctive corrosion resistance [3,4]. It indicates that Ni-based Nb-bearing bulk metallic glasses (BMGs) possess the better mechanical properties than other Ni-based ones [5,6].…”
