【摘要】 本文研究了以木炭和尿素为渗剂,用KS牌号催渗剂的快速固体软氮化工艺。试验证明,在软氮化温度一定时,在相同时间内,加催渗剂的渗层深度比不加催渗剂的有大幅度增加,且硬度有较大提高,硬度梯度较为平缓。更多还原

【Abstract】 This paper deals with the research on a new rapid pack nitrocarburizing process in which charcoal and ur(?)a were used as the aitrocarburizer and KS Type as the cntalyst, The results were shown that under a definite temperature and same period condition thicker nitrocarburized layer, higher hardness and evener hardness-gradient are obtained by this process as compared with those (?)btained by the pack nitrocarburizing process without catalyst.更多还原
