Multi-element alloy filler method and the tungsten inert gas (TIG) cladding process were used to fabricate Fe-Co-Cr-Ni-Mo(x) multi-element alloy claddings, and the microstructure and wear properties of the claddings were studied. In the absence of Mo, the claddings formed a face-centered-cubic (FCC) solid-solution phase. When the Mo concentration was increased, the claddings comprised not only the primary FCC phase but also a phase with the characteristics of a eutectic mixture of the FCC phase and or phase. The microhardness of the claddings increased from 210 to 465 HV upon the addition of Mo due to the formation of the sigma phase. Claddings with higher microhardness showed better wear performance due to precipitation strength and solid solution strength. (C) 2009 Elsevier BY. All rights reserved.
