Abrasive materials from metal-like refractory compounds — A review

Abstract

1. Refractory compounds of the transition metals surpass traditional carborundum and electrocorundum abrasive materials in both abrasive power and wear resistance in the microcutting of titanium. No direct correlation is observed between abrasive power and any one physical property constant, since abrasive power is a function of more than one physicomechanical characteristic. 2. The abrasive power of refractory compounds can be increased by preparing them in the form of mono- and polycrystals with a more favorable grain geometry and also by cementing them with metal binders. 3. Refractory compounds can be employed to improve the finish of ground surfaces, in pastes, and as fillers in diamond wheels.
