Abstract

ABSTRACT Corrosion control for metals is importance of technical, economical, environmental, and aesthetical . The use of corrosion inhibitors from natural product is one of the best ways to slow the rate of corrosion of metals and alloys. The use of extract inhibitors from natural product is the best alternative, because it is non-toxic, environmentally friendly, biodegradable, does not contain heavy metals, easy to obtain, inexpensive, and available in large quantities. The organic compounds contained in the extracts of natural product such as tannins, amino acids, phenolics, and alkaloids contain hetero-atomic groups which can inhibit corrosion rate and are interesting to study. With the development of science and technology, many methods are used to protect the corrosion, such as, electroplating, coating, and organic inhibitor show real promise such as Theobroma cacao peels extract. Although substantial research has been devoted to corrosion inhibition by plant extracts, reports on the detailed mechanisms of the adsorption process and identification of the active ingredient are still scarce. The addition of polar extract of cacao into a solution of HCl 1.5 mol/L is very effective to reduce the attack surface corrosion on mild steel, and can maintain its mechanical properties.The present paper consciously restricts itself mainly to plant materials Theobroma cacao peels extract as green corrosion inhibitors. Keywords: Theobroma cacao, Corrosion inhibitor, Plant product, Coating
