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.
Claims14
A point for an excavating tooth having a working portion to contact the ground during operation of the earthmoving equipment, the working portion including a steel substrate having oppositely-facing surfaces extending to a distal end, a cavity formed in each of the oppositely-facing surfaces extending rearward from the distal end, a composite coating filling each of the cavities to overlay those portions of the oppositely-facing surfaces and the distal end that are within each of the cavities, and a shell secured to the substrate rearward of each of the cavities to define an outer shape of the composite coating, the composite coating comprising a porous wear resistant material infiltrated by a matrix material wherein the matrix material is principally ductile iron and bonds the composite coating to the working portion and the shell.
