Cobalt Alloy Coating

Cobalt Alloy Coating refers to the application of a thin, highly durable layer of cobalt-based superalloy (such as Stellite or tribaloy variants) onto a substrate material, typically applied via thermal spray (HVOF) or welding (hardfacing). The purpose of the coating is to transfer the alloy's superior surface properties—specifically exceptional resistance to wear, cavitation, galling, and high-temperature oxidation—to a component that may require a cheaper or less specialized core material. These coatings retain hardness and corrosion resistance even when red-hot, making them vital for protecting critical parts in gas turbine blades, engine valves, bearing surfaces, and industrial mixer components operating in extreme heat and abrasive environments. Zeron Fastners specializes in providing precursor materials and finished components with high-integrity Cobalt Alloy Coatings.
