Abstract
A method for coating the internal cylinder bores of a cast aluminum engine block comprising the steps of casting an engine block of aluminum alloy, thermally spraying a wear-resistant coating onto cylinder walls in the engine block by melting the tip of a rotating iron-based alloy rod with a plasma torch within cylinders in the engine block, and honing the cylinder walls to a chosen size.
