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