鉄의 耐磨耗性의 物理的 性質

The sample was prepared by nitration at 650℃ in the nitration bath for the time duration of 30min., 60min. and 120min. respectively. Nitration treatment was performed by using the CHNO type liquid agent. Electrical resistivity, saturation magnetization and coercive force has been studied for each aamp1e. Electrical resistivity and saturation magnetization increase with the increasing of nitration time. Wear resistance has the same inclination of the above properties, but coercive force has the opposite tendency. So, it appears that wear resistance is linearly propertioned to electrical resistivity and saturation magnetization.
