Abstract
A composite wire useful for arc gun spraying is formed of an alloy sheath comprising iron, nickel, or cobalt, and a core comprising boron-containing powder of boron and/or boron carbide sufficiently fine in size such that the boron is substantially dissolved in a coating produced by arc gun spraying the composite wire. Where the boron substance includes boron, the core should further comprise fine carbon powder less than 20 microns in size blended with the boron powder. Preferably a substantial portion of the boron-containing powder is less than 20 microns. In a particularly desirable embodiment, the sheath is formed of mild steel and the core comprises boron carbide and an alloy powder such as ferromolybdenum.
