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KNKC测量方法, 并阐述KNKC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KNKC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KN的测量。

关键词: 氮碳共渗, 激光氮势传感器, KN, KC, SPCC钢, 疏松

Abstract: Taking nitrocarburizing atmosphere as the research object, hydrogen sensor with oxygen probe and laser nitrogen potential sensor measure methods of KN and KC were introduced, and the influence of KN and KC 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 KN and KC of the nitrocarburizing atmosphere, and even if the gas ratio changing during the process do not effect the measurement of KN.

Key words: nitrocarburizing, laser nitrogen potential sensor, KN, KC, SPCC steel, porosity
