Metal Alloys Wear and Properties

The theory of fracture in brittle materials is applied to the analysis of the wear of grinding wheels. The wear of grinding wheels includes three kinds of process : the fracture of bond posts, the fracture of grains and the abrasive wear of grains, while the present discussions are concerned with the case where the first two kinds are predominant. The theoretical analysis predicts the characteristic dependence of the wear rate and the size distribution of wear fragments on the grinding force and the bonding-strength of grinding wheels. The predictions are almost supported by the experiments on grinding wheels of different grades.
