摘要
用电化学方法研究了不同参数设置下的交变电场对点蚀破坏 18 8SS电极的修复效果 ,讨论了各参数的敏感取值范围 ,并通过正交试验寻找了 18 8SS在 1.0mol/LH2 SO4溶液中的最佳修复电场条件 ,即EH=10 0 0mV ,EL=- 2 0 0mV ,R =1,F =10Hz。在此基础上 ,提出了该技术的应用条件 。
The repairing effect of alternating voltage electric field with different parameters on the pitted 18-8SS electrodes were investigated by means of conventional electrochemical measurement techniques. The sensitive ranges of parameters were discussed. Combining with perpendicularity experiment, the optimum repairing conditions of 18-8SS electrodes was obtained in 1.0 mol/L H-2SO-4 solution,i.e. E-H=1 000 mV, E-L=-200 mV, R=1, F=10 Hz. Aside the applied condition of the technical was summarized as suitable to the systems that could show obvious passive region in repairing medium.
