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.
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.
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.
腐蚀是一个具有挑战性且可能有害的过程，它涉及金属结构通过与环境成分发生反应以及电或化学过程而持续、渐进的劣化。为了抑制腐蚀，会添加各种添加剂。另一方面，传统添加剂含有对环境有害的物质。与标准缓蚀剂相比，表面活性剂成本更低、易于制造，并且具有高抑制效率和低毒性。它们经常被用作缓蚀剂来保护金属材料免受腐蚀。
表面活性剂分子的两亲性质促进了在诸如金属/金属氧化物 - 水界面等表面的吸附。表面活性剂在金属和金属氧化物上的吸附形成了一道可以防止腐蚀的屏障。
这篇关于表面活性剂作为缓蚀剂的综述旨在对各种表面活性剂的物理和化学性质、表面活性剂在缓蚀方面的影响以及用于缓蚀的表面活性剂进行系统评估，这些可用于提高表面活性剂在各种环境中作为缓蚀剂的使用效果。这里还讨论了几个参数对表面活性剂分子系列抑制腐蚀潜力的影响。
