We study the corrosion of carbon steel in chloride-containing corrosive media inhibited by xanthan gum and its composition with a biogenic surfactant. It is shown that the xanthan biopolymer is an efficient corrosion inhibitor in steel due to the adsorption and formation of complexes with iron ions. The addition of trehalose lipid surfactants to corrosive media synergistically enhances the action of xanthan gum. The results of electrochemical impedance spectroscopy reveal the formation of a protective barrier layer on steel in the medium under the influence of inhibiting composition. The elevation of corrosion resistance of the metal in inhibited media is confirmed by the data of optical microscopy.

黄原胶生物聚合物对碳钢腐蚀的抑制

我们研究了碳钢在含氯腐蚀介质中的腐蚀，黄原胶及其含有生物表面活性剂的成分。结果表明，由于与铁离子吸附并形成络合物，黄原胶生物聚合物是一种有效的钢腐蚀抑制剂。将海藻糖脂质表面活性剂添加到腐蚀性介质中可协同增强黄原胶的作用。电化学阻抗谱的结果表明，在抑制成分的影响下，在介质中钢上形成了保护屏障层。光学显微镜数据证实了金属在抑制介质中的耐腐蚀性能的提高。
