Microstructural study and wear behavior of ductile iron surface alloyed by Inconel 617.

Highlights: [•] The Ni-base alloy was deposited on the surface of ductile iron by TIG welding process. [•] Microstructure of alloyed layer consisted of carbides embedded in Ni-rich dendrite. [•] Hardness and wear resistance of coated sample greatly improved. [•] The formation of oxide layer and delamination were dominant mechanisms of wear. [Copyright &y& Elsevier]
