Development of research on erosion of materials

Abstract

The erosion is one of the main reasons of material destruction and equipment failure.The essence and theories of erosion are introduced and the primary influencing factors on erosion are also summarized.The investigation result shows that erosion is a phenomenon of material loss caused by the impact of liquid or solid particles with definite velocity and attack angle upon the materials surface.The weighing system of erosive amount possesses different theoretical model,depending on whether the material is plastic or brittle.The factors which have influence on the erosion are mainly the particle characteristics,environmental condition,and materials characteristics.
