Abstract

A study for amorphous alloys with high elongation and high corrosion resistance for thermal spray coating was carried out on Ni-based alloys. The corrosion weight loss of as spun Ni-Mo-B ternary alloy shows the very low value less than 0.5 mass%/day. The corrosion weight loss of quenched Ni 66Mo15B19 alloy is not dependent on quenching rate of the samples. The sprayed Ni66Mo15B19 alloy has 5 times as corrosion resistance as hastelloy and exhibits same hardness as sprayed Fe45Cr35P13C7 alloy on commercial and Cermet. From these results, thermal sprayed Ni-Mo-B alloy is expected as combined coating with high wear resistance and high corrosion resistance.
