Abstract

A hard facing is applied to metal surfaces having a softening point above that of the facing alloy and particularly to the valves of internal-combustion engines, by flame-spraying a powdered cobalt-base alloy containing chromium and 1.6 to 2.6% of boron. Best results are obtained from an alloy containing: .C.0.9 to 1.4% .Cr.26.0 to 30% .W.3.5 to 5.5% .Si.0.70 to 1.75% .B.1.75 to 2.25% .Fe.not more than 3% .Ni.not more than 3% .Co.balance Particle size of the powder is less than 100 mesh and the powder may be either milled or fragmented, but is preferably a 50-50 mixture of the two. Particularly good results are obtained when the alloy is carried in a stream of non-oxidizing gas, such as a nitrogen hydrogen mixture through an oxy-acetylene flame, the carrier gas also forming a shield. The metal article may be preheated, e.g. to 350 DEG F., before spraying, and after spraying is heated to a temperature below its softening point to fuse the coating. Reference has been directed by the Comptroller to Specification 843,423.
