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.
