测定了Fe/H_2SO_4,Fe/H_2SO_4+Na_2SO_4,Fe/H_2SO_4+Fe_2(SO_4)_3和Fe/H_2SO_4+NaCI四种体系在磁场或/和缓蚀剂作用下的极化曲线,指出腐蚀的主要控制是阴极过程,H_2SO_4中加入少量Na_2SO_4不影响其结果,但加入Fe_2(SO_4)_3,NaCI会因Fe~(3+),CI~-的作用而影响结果。分析了磁场,缓蚀剂、CI~-和Fe~(3+)单一和联合对Fe/H_2SO_4阴极和阳极极化行为的影响,提出在磁场和缓蚀剂作用下上述四种体系阴极析氢总电流密度的表达式。
The polarization curves of Fe / H_2SO_4, Fe / H_2SO_4 + Na_2SO_4, Fe / H_2SO_4 + Fe_2 (SO_4) _3 and Fe / H_2SO_4 + NaCI under magnetic field or / and corrosion inhibitor were measured. However, adding Fe_2 (SO_4) _3 to Na_2SO_4 in H_2SO_4 did not affect the results. However, the effect of Fe_ (3 +) and CI_ - was affected by the addition of Fe_2 (SO_4) _3. The effects of magnetic field, corrosion inhibitor, CI ~ - and Fe ~ (3 +) single and combined on the polarization behavior of Fe / H_2SO_4 cathode and anode were analyzed. The results show that under the action of magnetic field and corrosion inhibitor, the total cathodic hydrogen evolution current The expression of density.
