Abstract

A coating (4) that is metallurgically bonded to a metal substrate (2) to protect the substrate includes carbide precipitates (10) of irregular and angular shape and a matrix (12) in which the precipitates are embedded. In a flame spraying procedure that utilizes a wire having a metal case and a core containing metal carbides, metals are deposited on the substrate as a basic coating. When that coating is subjected to a carbon rich environment, the carbon unites with the more reactive metals in the basic coating to form carbide precipitates of those metals, leaving the remaining metals to form the matrix. The carbide precipitates possess irregular and angular configurations and remain firmly embedded in the matrix, even though some of the matrix may disappear through the effects of erosion, corrosion, abrasion or wear.
