Solid Particle Erosive Wear Testing

This article addresses the important variables in erosion, such as particle impact velocity; particle impact angle; particle size, shape, and material; and ambient temperature. It describes four erosion test methods: the gas-blast method, a method using a centrifugal accelerator test rig, the wind-tunnel test, and the whirling arm test. The article also details the various test methods used to measure impact velocity of particle and data analysis and interpretation of these four methods.
