Abstract
A method for impregnating an iron product with a hard wear-resistant material surface layer comprises providing a pattern of particles onto a high temperature adhesive layer on a sand core and casting of the iron melt around the particles so as to produce an iron product. Preferably, the pattern of particles is produced by providing a mesh plate having a desired pattern of holes and spreading the particles onto the sheet. The pattern of particles is then transferred on to the adhesive layer so as to minimize contact with the adhesive. This can be accomplished, for example, through the use of adhesive tape. Preferably, the iron product of the present invention comprises ductile iron while the wear-resistant material comprises tungsten carbide which can include about 12 wt % Co.
