Green Methods for Corrosion Control

Abstract

Corrosion of metals is a serious environmental problem. Most of the corrosion inhibitors are synthetic chemicals that are hazardous to environments and expensive. Today, there has been an increasing search for green corrosion inhibitors, due to the toxicity of some inhibitors. Green corrosion inhibitors are biodegradable and free of heavy metals or other toxic compounds. There is an intensive effort underway to develop new plant origin corrosion inhibitors for metal subjected to various environmental conditions. Salts of rare earth elements can be also used as inorganic alternative nontoxic corrosion inhibitors. Sol-gel coatings can be recommended as green protective films for metal corrosion. The origin of sol-gel process, its advantages and limitations, and the type of coating method are presented in this chapter, as well as a brief summary of recent literature concerning the use of hybrid inorganic-organic sol-gel and nanostructured sol-gel protective coatings for metal corrosion in different media.

Expired Colxacillin, Amoxicillin, and Ceflaxin Drugs as Inhibitors for Low Carbon Steel Corrosion in Sodium Chloride

“…When calculating the corrosion current, the method can be used is the Stern-Geary by extrapolation of anodic and cathodic Tafel lines to the point that gives logicorr and the conformable corrosion potential (Ecorr) for inhibitor-free salt and different concentration of the antibiotics used. All practical experiments were done at 25 • C [13].…”

Current Status, Opportunities and Challenges of Green Corrosion Inhibitors

“…The action of the green corrosion inhibitors is also influenced by the structure of the ingredients which can be summarized as follows [16]:…”

Self-Healing Epoxy Coating with Microencapsulation of Linseed Oil for the Corrosion Protection of Magnesium (Mg)

“…The application of coating is useful when other ways, such as selection of materials, design and control of the environment are minimal. Coatings can be applied to any material (inorganic, metallic or organic) and are effective for prevention of corrosion in a wide range of industries, including the automobile, marine, infrastructure, aerospace, telecommunications, food and drink [1][2][3][4][5]. One of the most common and effective methods of protecting bare metal from oxidation has been the application of organic coatings [2,6,7].…”

Nevertheless, organic coatings are subjected to mechanical damage which can cause coating failure and then water will penetrate through the coating and cause corrosion of the metal [8,9].…”
