近年来为提高渗氮质量,国内外出现了可控渗氮法。文献[1]提出通过预先试验,经气体分析测定氨分解率,得出氮势临界值和时间关系的经验公式,以此作为控制渗氮工艺的一种依据。本文则在文献[2]所报导的研究渗碳和渗氮反应动力学的电阻松弛法(用铁箔试样)的启发下,提出了电阻法。即通过测定金属簿片或金属丝试样的 In recent years to improve the quality of nitriding, controlled nitriding appeared at home and abroad. Literature [1] proposed through empirical experiments, gas analysis of ammonia decomposition rate, the empirical formula of the critical value of the potential of nitrogen and time, as a basis for controlling the nitriding process. In this paper, we propose a resistance method based on the resistivity relaxation method (using a foil sample) studied in the carburization and nitriding reaction kinetics reported in [2]. That by the determination of metal film or wire sample
