This paper outlines various types of erosive-wear test apparatus. Revolving arm erosive-wear test apparatus is one being used more generally. The structure design and improvement for this test apparatus are carried out. By using trough wheel feed unit to increase abrasive powder feed stability, and using PWM regulating speed circuit and light-electricity measuring speed circuit and PID automatic adjusting system to control speed, the accurate of impact speed and abrasive powder feed rate has been improved enormously. The preliminary examination indicates that this test apparatus have a good experimental data stability, a high performance. So this test apparatus is suited to study erosive-wear mechanism and material wear-resisting performance test.
