Abstract
A system and method of cladding a carbon steel piece with stainless steel according to which the carbon steel piece is cleaned, heated, coated with the stainless steel, and strengthened. In an exemplary embodiment, coating the carbon steel piece with the stainless steel includes melting the stainless steel, atomizing the melted stainless steel, and spraying the atomized stainless steel so that at least a portion of the atomized stainless steel is deposited on the carbon steel piece to thereby coat the carbon steel piece with the stainless steel.
