It is shown that the supernatant of trehalose-lipid culture liquid, which is the product of vital activity of R.erythropolis Au-1 bacteria, exerts an anticorrosion influence on 20 steel and aluminum both in a 0.1% NaCl medium and in a model solution of stratal water. Thus, in 0.1% NaCl, within the temperature range 25–50°С, the supernatant of trehalose-lipid culture liquid makes the corrosion rate of 20 steel 6.2–4.3 times lower and the corrosion rate of aluminum 2–3.8 times lower. At the same time, in the model solution, the corrosion rates become 2.9–1.5 times lower for 20 steel and 3.1–3.2 times lower for aluminum. It is shown that the inhibiting properties of the supernatant of trehalose-lipid culture liquid are explained by its retarding action upon both electrode reactions caused by its adsorption on the metal surfaces.

海藻糖-脂质培养液上清液对氯化物溶液中20钢和铝腐蚀的影响

结果表明,作为R.erythropolis Au-1细菌生命活动产物的海藻糖脂质培养液上清液,在0.1% NaCl培养基和模型溶液中对20钢和铝均有防腐作用。地层水。因此,在 0.1% NaCl 中,在 25-50°C 的温度范围内,海藻糖脂质培养液的上清液使 20 钢的腐蚀速率降低 6.2-4.3 倍,铝的腐蚀速率降低 2-3.8 倍。同时,在模型解决方案中,20 钢的腐蚀速率降低了 2.9-1.5 倍,铝的腐蚀速率降低了 3.1-3.2 倍。结果表明,海藻糖-脂质培养液上清液的抑制特性可以通过其在金属表面吸附引起的两个电极反应的阻滞作用来解释。
