Academic Study Submitted by Xinhua Zhao
This paper was submitted by Xinhua Zhao, a graduate student at the Material Science & Engineering College of Shandong University in China. The Shandong Material Science &
Engineering College extensively studies shot peening and blast cleaning and provides technology support to Shandong Kaitai Metal Abrasive Company, one of China’s largest
metal abrasive producers. According to Mr. Zhao, his study on the wear failure of high carbon cast steel shot brings new concepts to the abrasive field.

Abstract
The ERVIN test machine was used in this study to mimic the actual blast cleaning process. The high carbon cast steel shot sample, heat-treated
at five different temperatures, are put into a ERVIN tester and ran for predefined cycles. The wearing of the samples were examined under a
magnifier. The failure ratio was defined and its influencing factors were studied. The results show that the failure modes, including brittle
fracture, surface peeling and core spall, can be analyzed by means of failure ratio represented by the defined weight ratio Gf/Gt, the failure
ratio are affected by the heat treatment, ERVIN cycle, microstructure and flaws, particle size, target hardness. Impact velocity and impact
angle play an important role in the wearing failure process.
