ABSTRACT:
A method for impregnating a metal product with a hard wear-resistant surface area comprises providing a wear-resistant layer in the form of a sintered sheet having a pattern which facilitates metallurgical bonding with a metal melt and optionally, at least one "pin" integrally attached onto a surface of the sheet. This wear-resistant layer is attached onto the sand core and a metal melt is cast so as to produce the final product. This method can be used to produce a variety of metal products although cast iron is preferred. Moreover, this process can effectively employ any of the hard phases which can be sintered, e.g., tungsten carbide, chromium carbide, and the like.
