Wear Resistance of Industrial Pure Iron Treated by Nitriding and Quenching Followed by Aging Process

Abstract

The wear resistance without lubrication were studied experimentally for iron nitrides compound layer and high nitrogen martensite phase formed in the material surface by using industrial pure iron treated by nitriding and quenching followed by aging process. As a result both the compound layer where the generation of pores was suppressed by lowering the nitriding temperature and the high nitrogen martensite phase showed the same trend of high wear resistance. However, the pores in the compound layer decreased the wear resistance due to the acceleration of crack propagation.
