BACKGROUND The majority of well-known inhibitors are organic compounds containing multiple bonds and heteroatoms, such as O, N or S, which allow adsorption onto the metal surface. These compounds can adsorb onto the metal surface and block active surface sites, reducing the rate of corrosion. RESULTS A comparative theoretical study of three benzimidazole isomers, benzimidazole (BI), 2-methylb...

Economic losses due to corrosion are direct, as well as, indirect and affect the economy of country. Corrosion inhibitors are one of the widely used methods to control corrosion. Particular advantage of corrosion inhibitor is that often can be implemented or changed in situation without disturbing a process. Due to toxic nature and high cost of some inhibitors currently in use it is nearly to d...

Corrosion is one of the major reasons for wear and tear of equipments. It is also responsible for reducing the life of equipments. Many accidents occur because of failure of pipelines due to corrosion. There are many methods to minimize corrosion. Cathodic protection, use of inhibitors, use of anticorrosive coatings is few methods used for this purpose. The presence of moisture in the atmospher...

In principle, any method to determine the corrosion rate can be used to test a corrosion inhibitor. The primary criterion for evaluation is the inhibitor efficiency. Inhibitors having sufficiently high efficiency are tested for "side effects," which include environmental compatibility, emulsion formation, viscosity and pour point density. Finally, the inhibitor formulation is tested in the fiel...

A combined process was developed to inhibit the corrosion both in the pipeline of reclaimed water supplies (PRWS) and in downstream recirculating cooling water systems (RCWS) using the reclaimed water as makeup. Hydroxyl carboxylate-based corrosion inhibitors (e.g., gluconate, citrate, tartrate) and zinc sulfate heptahydrate, which provided Zn(2+) as a synergistic corrosion inhibition additive,...

Selection of an appropriate corrosion inhibitor, inhibitor combination or package is an exceptionally cost effective and materials saving measure in various industries. Current trends and novel approaches in corrosion inhibitors are reviewed here. Recent developments in the inhibition technology are discussed in accordance with the areas of application of inhibitors.

A corrosion inhibitor is a chemical substance which, when added in small concentrations to an environment, minimizes or prevents corrosion [I]. Corrosion inhibitors are used to protect metals from corrosion, including temporary protection during storage or transport as well as localized protection, required, for example, to prevent corrosion that may result from accumulation of small amounts of...

The idea of smart corrosion inhibition is basis on either inhibitor consumption where it is needed or reducing harmful matrix interaction with it. In addition, applying corrosion inhibitor in a coating causes many problems such as loss of inhibition capability, coating degradation, or both. A useful technique to overcome this problem is applying of inert host systems of nanometer dimensions as ...

The inhibitive effect of a few thiols were examined as corrosion inhibitors for the corrosion of zinc in 1N HCl and 1N H2SO4 by conventional weight loss and gasometric methods. Results obtained show that all the thiols exhibited high inhibition efficiencies. The inhibition efficiency was found to increase with increase in the inhibitor concentration. The adsorption of the inhibitors obeyed Temk...
