• We have been investigating the nitrogen penetration mechanism into high carbon chromium bearing steel JIS-SUJ2 on carbonitriding processes. In the course of carbonitriding experiments under various conditions and EPMA analyses, the influences of carbon activity and base gas components on nitrogen penetration behavior were examined. As a result, the nitrogen penetration content of steel increased with the decrease of carbon activity and H_2 partial pressure, and with the increase of undecomposed NH_3 partial pressure. While, the partial pressures of CO and N_2 had almost no effect.
