摘要:
采用成膜剂和封孔剂复配制备一种封孔 - 成膜剂。通过电位 - 时间曲线、极化曲线、电化学阻抗测试、浸泡实验以及孔隙率测试表征了该封孔 - 成膜剂对薄镍层耐蚀性能的影响。结果表明:对薄镍层经过封孔 - 成膜剂工艺处理之后的薄镍层在 3.5 wt.%NaCl 溶液中的开路电位和自腐蚀电位较正,自腐蚀电流密度较低。电化学传质电阻较大,长期浸泡过程中的腐蚀速率较低。经过该工艺处理后的薄镍层孔隙率降低,耐腐蚀性能得到大幅提高。
Abstract:
A sealing film-forming agent was prepared by compounding a film-forming agent and a sealing agent. The effect of the sealing film-forming agent on the corrosion resistance of thin nickel layer was characterized by potential time curve , polarization curve , electrochemical impedance test , immersion test and porosity test. The results showed that the open circuit potential and self-corrosion potential of the thin nickel layer treated by hole sealing-film forming agent process were positive and the self-corrosion current density was low in 3.5 wt.% NaCl solution. The electrochemical mass transfer resistance was large , and the corrosion rate was low during long-term immersion. The porosity of the thin nickel layer treated by this process was reduced and the corrosion resistance was greatly improved.
