A Review on Green Corrosion Inhibitors for Protection of Archeological Metal Artifacts

Because of their toxicity, traditional corrosion inhibitors are no longer allowed due to an increase in environmental awareness and a change in the laws. Environmentally friendly corrosion inhibitors are becoming more popular. Corrosion inhibitors derived from natural products are a good choice because they contain a wide range of active elements that can be used in organic compounds to bind to metal surfaces and form a protective film that prevents further corrosion. These active elements are found in abundance in natural extracts, making them a good starting point for developing new green corrosion inhibitors. Several natural ingredients are investigated, as well as their usage in different techniques, such as steel reinforcement incorporated in concrete. Ionic liquids, which are regarded to be new corrosion green inhibitors, are described in this research using unique synthetic techniques. This research also discusses the adsorption process, the action of these green inhibitors in diverse fluids, and their protective function for various metal alloys. A look at how vapor-phase inhibitors are used in industry and how they work is also explored. The researchers used inhibitors to prevent metal artifacts against corrosion in general and the corrosion of metal artifacts from corrosion. As a result, one of the most significant strategies for protecting our metal cultural legacy is the use of corrosion inhibitors. Unfortunately, the inhibitors of preservatives are dangerous as well. More and more people are becoming concerned about the environment and the need to develop more ecologically friendly technology, which has led to an increase in the focus on developing renewable solutions. To conserve metallic cultural heritage, the use of green corrosion inhibitors has become one of the most used ways. The effects of economic, safety, and environmental factors on corrosion of metal artifacts and methods used for their protection, metal types and their chemical and electrochemical properties, practical steps for treating the pre-surface before inhibitor use; types of green inhibitors and their features; a review aimed at clarifying the most important key topics in this crucial research area. Techniques for conducting electrochemical and surface examination of metal artifact surfaces before and during the application of inhibitor are outlined.
