Study on relationship between erosion characteristic and mechanical properties in different materials

Abstract

MSE (Micro Slurry Jet Erosion) test is a new method for evaluating material properties in a micro area. In this method, erosion resistance was measured by colliding fine particles to the material surface with high speed. The erosion characteristics and mechanical properties of pure metallic materials, ceramics, coating material and surface treated material, were evaluated in this study. Mechanical properties and erosion rate has correlation in the metallic material when shape of impact particles was polygonal. On the other hand, relationship between mechanical properties and erosion rate showed correlation in the ceramic material when impact particles were spherical.
