Effect of sintering temperature on the electrochemical, hardness and tribological properties of aluminide-reinforced austenitic stainless steel

摘要

The present study investigates the effect of aluminide (Fe_3Al and Ni_3Al) addition and sintering temperature on the densification, hardness, wear and electrochemical behavior of austenitic (316L) stainless steels. As compared to solid-state sintering (1200 deg C), supersolidus sintering (1400 deg C) improves the overall performance of both straight 316L as well as 316L-aluminide composites. The addition of Ni_3Al and Fe_3Al to 316L stainless steels improve the mechanical and wear properties without any significant degradation of corrosion resistance.
