| Abstract: | As a pollution-free and energy-saving technique, rapid nitriding can not only improve the quality of nitriding-workpiece but also reduce the cost of gear processing. The latest researches on rapid nitriding of steel are described, and the principle of accelerated permeance analyzed. The influences of three factors, i.e. opti- mization of process parameters, rare-earth catalyzing, and surface treatment, on nitriding are discussed. |

| Keywords: | rapid nitriding rare-earth catalyzing surface-nanocrystallization preoxidizing |
