An Overview of the Polymeric Materials that can be Used to Prevent Metal Corrosion: A Review

Abstract

Traditional study has discovered that natural materials such as wood are scarce and that synthetic materials can serve as suitable substitutes. Polymer chemicals, plant materials, chemical compounds, inorganic compounds, and other corrosion inhibitors all use metals. When technology fails, corrosion is one of the most severe consequences, causing harm to the financial system, natural resources, and people's lives. Natural materials such as wood are scarce, according to traditional research, and synthetic materials may serve as suitable replacements. Polymers as corrosion inhibitors have piqued researchers' attention from both a theoretical and practical standpoint. It has been seen from the research that natural polymer inhibitors exhibits more than 90% efficiency and good surface cover on carbon steel surface. A summary of forms of corrosion, corrosion processes, and recent work on the application of polymer inhibitors on the basis of parameters such as cost, convenience of use, environmental impact, and reliability has been reviewed.

Corrosive Influence of Varied Salt Solutions Concentration on Mild Steel

“…As illustrated in the two figures, the specimens demonstrated lower hardness after immersion in the corrosive media when compared to their hardness values before immersion. This is an indication that the chemical/electrochemical reactions of all the salt solutions affected the surfaces of the specimens[1], which enhanced indentation of the specimens. It has been reported that early stages of corrosion largely depends on roughness of the surfaces of metals/alloys because dense oxide films on metals or alloys surfaces that are protecting the metals or alloys from corrosion can be easily destroyed at high surface roughness[22].…”

“…Corrosion is an irreversible interfacial reaction of a material (metal, ceramic, and polymer) with its environment, which results in its consumption or dissolution into the material of a component of the environment. Often, but not necessarily, corrosion results in effects that are detrimental to the usage of the material considered [1]. When the surfaces of materials deteriorate due to chemical reactions with their surroundings, corrosion has taken place.…”

“…The most commonly used metal is iron (usually steel), and the corrosion of this metal is the subject of the following question. Corrosion is shown by the rusting of iron (Fe2O3.H2O) and the forming of a green carbonate film CuCO3.Cu(OH)2 on copper [1].…”

“…Table 1 A table showing that most of the materials decay overtime [1] In electrochemical corrosion, atoms of metals/alloys are removed because of an electric circuit that is produced. Understanding corrosion processes aids in product design and selection to ensure high levels of safety.…”

“…The most important factor in corrosion prevention is safety but economy is also important. Corrosion costs money not only because the object must be removed, but also because time and processing materials are wasted [1]. Corrosion of mild steel in particular is of great concern to governments and stakeholders in the industrial sector because of the wide areas of application of mild steel.…”
