Abstract
Titanium diboride is composited with about 11 to 13 wt pct of copper and about 2 to 4 pct of nickel, preferably by mixing the constituents in powdered form, heating the mixture to about 2,000 deg f, and then hot pressing at a pressure of about 3,000 psi and a temperature of about 2,650 deg f. The titanium diboride-copper- nickel composite composition possesses excellent strength and nonsparking properties useful in the fabrication of mining tools and implements. Note: the inventors are not Bureau of Mines personnel, so the patent evidently was developed under a BoM contract.
