Some Aspects of the Abrasive Wear of Transition-Metal Carbides
The results of abrasive-wear tests on some carbides are presented. The specimens were tested on a Kh4-B machine, using M. M. Khrush-chov’s standard procedure. A relationship has been established between the relative wear resistance of the carbides and their porosity, hardness, degree of plasticity, and nature of the materials. The wear resistance of the carbides is shown to decrease linearly with rise in porosity. No unique connection was found between the hardness and wear resistance of the carbides; this was due to one specific property of the materials investigated, namely their great brittleness. The results obtained are discussed in terms of the configuration-localization model.
