Abstract
A system and method of forming a wear resistant composite material includes placing a porous wear resistant filler material in a mold cavity and infiltrating the filler material with a matrix material by heating to a temperature sufficient to melt the matrix material, then cooling the assembly to form a wear resistant composite material. The system and method can be used to form the wear resistant composite material on the surface of a substrate, such as a part for excavating equipment or other mechanical part. One suitable matrix material may be any of a variety of ductile iron alloys.

1-65. (canceled)
A wear part for earth engaging equipment comprising:
- a metal substrate including a working portion for engaging earthen material, the working portion including a surface;
- an expendable sheet metal shell connected by welding or brazing to the substrate, a portion of the sheet metal shell being spaced from the substrate to define a cavity between the surface of the substrate and the shell;
- and
- a composite material substantially filling the cavity and forming a coating on at least a portion of the surface of the substrate, the composite coating comprising a porous wear resistant material infiltrated by a ductile iron matrix material, wherein the matrix material is principally ductile iron and bonds the coating to the working portion and the shell.
A wear part for earth engaging equipment comprising:
- a substrate including a base portion for attachment to the earth engaging equipment and a working portion for engaging earthen material, the working portion including a surface;
- and
- a composite material substantially filling the cavity and forming a coating on at least a portion of the surface of the substrate, the composite coating comprising a porous wear resistant material infiltrated by a ductile iron matrix material, wherein the matrix material is principally ductile iron and bonds the coating to the working portion and the shell.
