ABSTRACT:
Amorphous boron-carbon alloy cutting tool bits and methods of making them are described. The tool bits can be composites of conventional hard alloys containing the amorphous boron carbon alloy in a first layer over a conventional hard alloy layer such as cobalt bonded tungsten carbide. The amorphous boron carbon alloy used is preferably produced in bulk with a grain size less than 30 .ANG. and ground into a powder. The tool bits are produced by cold compressing, in a tool bit die, the lower layer material at about 2000 psi followed by hot compressing the composite containing the added amorphous boron carbon alloy powder at about 1350.degree.-1500.degree. C. The resultant cutting tool bit has a cutting lifetime at least four times that of conventional carbide cutting tool bits even when cutting such things as nickel superalloys at speeds in excess of 125 surface feet per minute (SFM).
