... that was caused by rock drill bits. The work of Sorokin ( Ref 9 ), one of several Soviet industrial wear investigators, is also worth citing. Bayer, Engel, and their coworkers ( Ref 10 , 11 ) constructed impact wear test equipment, of both the ballistic projectile ( Fig 2a ) and pivotal hammering type ( Fig...

... different types of test rigs have been developed for impact wear studies: ballistic impact testers and reciprocating hammer testers ( Ref 13 ). The following describes the features of each. Ballistic Impact Wear Apparatus In ballistic impact wear testers, repetitive impacts are achieved by firing...

... 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...

... (DSRW) abrasion test apparatus simulates one such environment (i.e., low-stress, three-body abrasive wear) ( Ref 34 , 35 ). This type of wear occurs in the mining industry in linkages, pivot pins, and wire ropes, which suffer slow wear from the sliding and rolling action of abrasive fragments of rock...
