MECHANICAL PROPERTIES AND ABRASIVE WEAR BEHAVIOR OF STEAM TREATED SINTERED IRON ALLOYS

摘要

Steam treatment is a surface treatment developed to improve corrosion resistance, hardness and wear resistance of sintered steels. In this research, sintered iron alloys samples were steam treated at 550°C for 30 min. The wear properties of sintered iron were improved by steam treatment and by the addition of alloyng elements. An increase in hardness was associated with an increase in wear resistance. The results reveal that the samples (P2 and P3) prealloyed with Cu, Ni and Mo can improve wear resistance of sintered steels.
