ABSTRACT:
A hard surfaced heavy duty cutting tool having an abrasive insert and method for hard surfacing and bonding metallic materials. The composition used in hard surfacing comprises a slurry coating including a high nickel, metal alloy powder and a fluxing agent. The slurry composition is fused at temperatures of about 1830.degree.-1925.degree. F. to bond an abrasive cutting element, such as tungsten carbide in a base metal matrix, to a cutting tool to form the primary working element thereof. The slurry composition is also fused at the same temperature range to form a wear surface of the tool adjacent to the abrasive insert as a hard surface, wear resistant coating in which abrasive compounds and other materials may be incorporated.
