摘　　要：以氮碳共渗气氛为研究对象,分别介绍了氢探头搭配氧探头和激光氮势传感器这两种不同的K_(N)和K_(C)测量方法,并阐述K_(N)和K_(C)在氮碳共渗工艺中对白亮层成分和组织结构的影响。结果表明,激光氮势测控系统可同时对氮碳共渗气氛的K_(N)和K_(C)进行测量和计算,即使在工艺过程中气体比例发生变化也不影响K_(N)的测量。Taking nitrocarburizing atmosphere as the research object,hydrogen sensor with oxygen probe and laser nitrogen potential sensor measure methods of K_(N)and K_(C)were introduced,and the influence of K_(N)and K_(C)on composition and structure of white layer in nitrocarburizing process was explained.The results show that the laser nitrogen potential measurement and control system can simultaneously measure and calculate the K_(N)and K_(C)of the nitrocarburizing atmosphere,and even if the gas ratio changing during the process do not effect the measurement of K_(N).
