Abstract:
BACKGROUND: Corrosion is a challenging and potentially harmful process that involves the continuing, impulsive deterioration of metallic structures via reactions involving environmental components and electro- or chemical processes. To inhibit corrosion, various additives are added. Traditional additives, on the other hand, contain environmentally hazardous substances. Surfactants are less expensive, easier to manufacture, and have high inhibitory efficacy and low toxicity compared to standard corrosion inhibitors. They are often employed as corrosion inhibitors to protect metallic materials against corrosion.
METHODS: Surfactant molecules\' amphiphilic nature promotes adsorption at surfaces such as the metal/metal oxide-water interface. Surfactant adsorption on metals and metal oxides forms a barrier that can prevent corrosion.
UNASSIGNED: This review of surfactants as corrosion inhibitors aims to offer a systemic evaluation of various surfactant physical and chemical properties, surfactant influence in corrosion inhibition, and surfactant used in corrosion inhibition that can be used to enhance the efficacy of surfactant use as corrosion inhibitors in a variety of environments. The effect of several parameters on the potential to suppress corrosion of surfactant molecule series is also discussed here.
摘要:
背景:腐蚀是一个具有挑战性且潜在有害的过程,涉及持续,通过涉及环境成分和电或化学过程的反应,金属结构的脉冲劣化。为了抑制腐蚀,添加各种添加剂。传统添加剂,另一方面,含有对环境有害的物质。表面活性剂更便宜,更容易制造,与标准缓蚀剂相比,具有较高的抑制效果和较低的毒性。它们通常用作腐蚀抑制剂以保护金属材料免受腐蚀。
方法:表面活性剂分子的两亲性质促进在诸如金属/金属氧化物-水界面的表面上的吸附。表面活性剂在金属和金属氧化物上的吸附形成可以防止腐蚀的屏障。
本文对表面活性剂作为腐蚀抑制剂的综述旨在对各种表面活性剂的物理和化学性质进行系统评估,表面活性剂对腐蚀抑制的影响,和用于腐蚀抑制的表面活性剂,可用于增强表面活性剂在各种环境中用作腐蚀抑制剂的功效。本文还讨论了几个参数对抑制表面活性剂分子系列腐蚀潜力的影响。
