A composite thermal spray powder, for producing abradable coatings, is substantially in the form of clad particles each of which has a core particle of boron nitride and subparticles of aluminum-silicon alloy. The subparticles are bonded to the core particle with an polymeric binder.

Boron nitride and aluminum thermal spray powder

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.
