【Abstract】 The current situation of study on erosion-corrosion mechanism and the influence of different environmental factors and alloy properties on erosion- corrosion is reviewed in this paper.The erosion-corrosion is mainly composed of two parts: erosion wear and electrochemical corrosion, of which the contribution to the total erosion-corrosion rate may depend upon the environmental factors. To protect metallic materials from erosion-corrosion the following measures may be effective: i.e. proper selection and addition of alloying elements, proper heat treatment and applied surface coatings as well. Meanwhile, the paper discusses the development of erosion-corrosion research in the future.更多还原
