本文用电化学技术测氢渗透瞬变曲线的方法,研究了pH、H_2S浓度、温度、NaCl浓度及电位等环境因素对钢在硫化物应力开裂中氢渗入钢难易的影响。研究结果表明,用这一方法所得到的结论,与前人用传统的定载荷拉伸、定变形弯曲或其它方法试验所得的结论平行不悖,因此,认为用电化学技术测氢渗透瞬变行为,对研究环境因素对钢的抗硫化物应力开裂影响,将是一种有用的手段。 In this paper, electrochemical transient permeation curves of hydrogen permeation were studied. The effects of environmental factors such as pH, H 2 S concentration, temperature, NaCl concentration and potential on the difficulty of steel infiltrated with hydrogen in the stress cracking of sulfide were studied. The results show that the conclusion obtained by this method is not inconsistent with the conclusion obtained by the predecessors using the traditional tests of constant load, constant deformation and other tests. Therefore, it is considered that the electrochemical permeation transient Behavior, the study of environmental factors on the sulfide stress cracking resistance, will be a useful tool.
