Abstract:
1. A method for forming a wear- and corrosion- resistant overlay on a metal substrate comprising: applying molten material comprising metal constituents of a Co-Cr-Mo alloy comprising between about 0.12 wt% and about 0.7 wt% C, between about 20 wt% and about 30 wt% Cr, between about 10 wt% and about 15 wt% Mo, between about 1 wt% and about 4 wt% Ni, and between about 50.30 wt% and about 68.88 wt% of Co; and solidifying the molten material on the substrate to form said overlay comprising said Co-Cr-Mo alloy . wherein the alloy has a hypoeutectic microstructure.
