1. M. Aramaki, M. Kozin, K. Yoshida, O. Furukimi, Effect of Nitriding-Quenching and Carburizing-Quenching on Wear Properties of Industrial Pure Iron, Journal of Heat Treatment and Materials, 10.3139/105.110346, 73, 3, 131-143, J. Heat Treatm. Mat. 73 (2018) 2, pp. 131-143, 2018.03, The wear properties of industrial pure iron treated by nitriding- quenching and carburizing-quenching were investigated. Both the nitrogen martensite and carbon martensite produced by each treatment exhibited the same high degree of wear resistance. The results of sliding tests showed that the nano-indentation hardness near the surfaces of both samples had increased. The surface hardening of the nitrogen martensite was more noticeable than that of the carbon martensite. EBSD analysis revealed that plastic strain had been induced on a relatively large scale (around 20 µm) after sliding in the case of the nitrogen martensite. It was found that the high wear resistance of the nitrogen martensite led to strain hardening through the effect of the load applied in the sliding test..
