ABSTRACT:
A tenacious wear resistant coating is applied with a high velocity oxygen-fuel thermal spray gun using a composite powder of aluminum and an iron base metal. The metal may be iron-chromium, iron-molybdenum, cast iron or a combination. A particular combination is a blend of a first powder and a second powder, the first powder consisting of a composite of aluminum subparticles and iron-molybdenum alloy subparticles, and the second powder consisting of a composite of aluminum subparticles and cast iron subparticles. An internal combustion engine block has such a coating applied to the cylinder walls.
