    Abstract

    Anti-wear property of industrial pure iron and High Strength Low Alloyed (HSLA) steel after nitriding followed by accelerated cooling was examined. The nitriding treatments were performed at 913K for 90 min. and were followed by oil-quenching. The hardness values beneath the surface in both the pure iron and HSLA steel were about 800 HV. The thickness of nitrided layer of the pure iron was smaller than that of HSLA steel. However, the wear depth per unit sliding distance in the pure iron was smaller than that in HSLA steel. It was inferred that the voids in the HSLA steel which were formed in a phase resulted in worsening the anti-wear property. These findings revealed that the pure iron after nitriding and accelerated cooling has excellent anti-wear property comparing with the HSLA steel.
