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 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, and in particular, ductile iron are 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. Preferably, both the sheet and the "pins" are made from the same mixture of a wear-resistant material, an organic binder, and at least one plasticizer.
