ABSTRACT:
A wear-resistant surface structure having a high resistance to impact and thermal shock, suitable for a wide variety of tools and implements, is prepared by bonding carbide particles together with a substantially pure copper matrix in the absence of oxygen. The carbide-copper surface structure can be bonded to the working surface of a ferrous tool simultaneously with the aforementioned bonding process, or at a later time. Although attachment of the surface structure to a ferrous tool normally requires heating of the tool to a softening temperature, such softening may be corrected by subsequently quenching the combined ferrous tool and carbide-copper surface structure from an austenitizing temperature without cracking the copper matrix. Refractory sheet materials are used to contain the carbide and matrix material during liquefaction of the matrix material during the formation of the surface structure.
