Abstract

Equipment having a protective coating layer for use in abrasive environments, e.g., sulfur-containing environments, is disclosed. The coating is formed from a single-component feedstock, as a Fe-based alloy composition comprising at least two refractory elements selected from Cr, V, Nb, Mo and W in an amount of up to 30% each and a total concentration of up to 40%. In one embodiment, the coating is applied by thermal spraying, followed by heat treatment for at least a portion of the refractory elements in the coating to fuse into the substrate forming a metallurgically bonded coating. The coating has an adhesion strength of at least 7,000 psi measured according to ASTM D4541. The coating layer is further characterized as being impermeable to corrosive environments showing no pin holes in the ferroxyl test according to ASTM A967 Practice E.
