采用动电位扫描与恒电位阳极氧化的电化学解吸研究了钢中的氢。通过测定08F和20号钢的充氢电位及这两种钢和1Cr18Ni9Ti不锈钢经不同介质充氢、不同条件解吸后的解吸氢量,结合理论分析,找出了阴极进入氢与阳极解吸氢的某些规律及其相互关系。
Potentiodynamic sweep and electrochemical desorption under potentiostatic oxidation are used to investigate the hydrogen in steel. Samples of 08F and mild carbon steel were galvanostaically H-charged for various times with the H-chargingpotential, φ_H, measured. The amount of H-desorbed electrochemically for both steels mentioned above and for 1 Crl8Ni9Ti stainless steel was determined in various H-charging media with different conditions of desorption. Some relationship between cathodic H-entering and anodic H-desorbing, as well as that between the H-ingress and the H-egress can be found.
