Abstract
A flame spray material in the form of a composite comprising (1) as a first component an alloy containing at least about 40% of its weight of at least one of nickel and cobalt, and about 1 to 6% by weight of boron, and (2) aluminum powder as a second component, the first component being present in about 66 to 99% by weight of the composite. The material, desirably blended with about 10% of an aluminum-molybdenum-coated nickel core powder, produces self-bonded wear resistant coatings which can be ground without cracking.
