Abstract
In one aspect, composite articles are described herein employing cobalt-based alloy claddings exhibiting high hardness and wear resistance while maintaining desirable integrity and adhesion to surfaces of metallic substrates. A composite article, in some embodiments, comprises a metallic substrate and a composite cladding metallurgically bonded to one or more surfaces of the metallic substrate, the composite cladding including cobalt-based alloy having a chromium gradient, wherein chromium content increases in a direction from the composite cladding surface to an interface of the composite cladding with the metallic substrate.
