Definition
The term “superabrasives” denotes abrasive grit materials with higher hardness (commonly higher than 4,000 HK) and refers to cubic boron nitride and diamond. Sometimes the term is also used to describe the tools made of these abrasives. Besides higher hardness, superabrasives are also characterized by higher wear resistance standing out from “conventional abrasives” like corundum and silicon carbide.
Theory and Application
Superabrasives are distinguished from conventional abrasives by their higher hardness, which is accompanied by higher Young’s modulus and heat conductivity but typically lower thermal stability (Table 1).
