Impact wear can be defined as the wear of a solid surface due to percussion, which is a repetitive exposure to dynamic contact by another solid body. It has not been studied as extensive as other wear mechanisms and the information on causes and actual data is quite scarce. In the present work an experimental wear tester is designed and used to study the impact wear phenomenon experimentally. It creates the consecutive impacts between balls and flat plate. The different ball sizes (up to 30 mm), impact velocities (up to 6 m.s-1) and impact angle (10°− 80°) can be tried by tester. The mass loss of plate is measured as the wear parameter. These measurements for different specimens revealed some aspects of their wearing behaviors. The obtained results could be helpful in optimal practical designs and explanation of some phenomena associated with impact wear.
