【Abstract】 The effects of alloying elements on the corrosion wear behavior of martensitic ductile cast iron was studied in this paper. The results show that the amount of carbides was decreased, the sizes of spherical graphite and the corrosion wear resistance were increased with the increase of silicon content and the addition of copper and nickel elements. The observation of wear morphology by SEM indicates that the corrosion wear mechanism of martensitic ductile cast iron is dominanted by abrasive wear, and the action of corrosion is inconspicuous.更多还原
