... contact. Hence, the spalling of gear teeth and bearing materials is also known as fatigue wear or rolling contact fatigue. Spalling damage on a surface can also occur from impact events. For example, the spalling of striking/struck tools is of considerable interest from the engineering, economic...

... soft and hard) by impact hammers and blow bars. The rationale for the development of the test apparatus was to be able to predict the wear, and hence the energy consumption, that occurred in the crushing and grinding of ore ( Ref 59 , 60 ). However, this test is applicable to any wear process in which...
