| Abstract: | In this paper, the operating environment with corrosive chemical substance, high temperature and stress of the valve seat of heavy duty engine is analyzed, and the mechanism of wear of the valve seat is discussed. According to the mechanisms of wear, the paper also introduces the existing types of materials and the basis for the designing of the materials for valve seat. At last, tendency of the research on the materials is presented. |
