Abstract
A method for impregnating a metal product with a hard wear-resistant surface layer comprises providing a wear-resistant layer in the form of a partially sintered sheet having at least one peg formed therein; attaching the wear-resistant layer to a mold surface; and casting a metal melt so as to produce a metal product having a wear-resistant material surface layer. Preferably the mold surface is a sand core and the sheet has a hexagonal pattern molded therein so as to form a plurality of pegs.
