Abstract
A composite article comprising a metal substrate having a cobalt-base alloy built-up surface portion consisting essentially of a cobalt-base alloy welding metal which has been deposited on said substrate by an overlay welding process using a cobalt-base welding metal which consists essentially of 1.1 to 3.0% Si, 0.2 to 0.5% C, 25.0 to 30.0% Cr, 0.1 to 1.0% W, 0.2 to 3.0% Fe, 0.4 to 6.0% Mo, 0.1 to 2.0% MN, 1.0 to 4.0% Ni, the balance being Co and incidental impurities, the percentage being on a weight basis. The built-up surface portion has high resistance to wear and to weld cracking.
