Abstract
1. Microhardness, abrasive grain strength, and abrasive power are not reliable criteria of the wear resistance of abrasive tools in the grinding of materials at high speeds. An understanding must be obtained of the mechanism by which the abrasive and work materials react with each other in the contact zone. 2. The abrasive power of most carbonitrides exceeds that of white electroco undum, but is less than that of green silicon carbide. 3. With rise in MeC content, the abrasive power of carbonitrides grows. The abrasive qualities of vanadium carbonitrides are particularly high, while zirconium carbonitrides are characterized by low abrasive power. 4. The majority of carbonitrides surpass green silicon carbide in wear resistance in the microcutting of titanium. Carbonitrides of low nitrogen content have very high wear resistance. The wear resistance of titanium carbonitrides is a linear function of their MeC content; the wear resistance of zirconium, vanadium, and niobium carbonitrides is represented by curves with minima at composition of about MeC0.4N0.6.
