铅在有机酸和湿度的存在下非常容易腐蚀。一种潜在的对策是通过将金属浸入羧酸钠溶液/悬浮液中来施加羧酸铅涂层。在这项工作中,我们报告的程度上的表面覆盖和耐腐蚀性的癸酸铅Pb(C10)2涂层作为处理时间的函数。结果表明,在0.05M癸酸钠溶液中,15 min后表面覆盖率达到91%,1h后表面覆盖率达到100%。如电化学阻抗谱所示,即使在浸泡6小时后,耐腐蚀性也继续增加。此外,我们表明,在平面运输的情况下,存在17 mm厚的扩散层,其中癸酸钠浓度从其体积值线性下降到几乎为零的固体/表面界面。
Lead is very susceptible to corrosion in the presence of organic acids and humidity. A potential countermeasure is to apply a lead carboxylate coating by immersing the metal in a sodium carboxylate solution/suspension. In this work we report on the degree of surface coverage and the corrosion resistance of a lead decanoate Pb(C10)2coating as a function of treatment time. Results show that the surface coverage reaches 91% after 15min and about 100% after 1h in a 0.05M sodium decanoate solution. The corrosion resistance, as indicated by electrochemical impedance spectroscopy, continues to increase even after 6h of immersion. In addition, we show that in the case of planar transport, a diffusion layer of 17mm thickness exists, wherein the sodium decanoate concentration drops linearly from its bulk value to almost zero at the solid/surface interface.
