Until recently, chromium based coatings were in widespread use due to their high mechanical properties as well as corrosion resistance. However, more and more stringent environmental and health regulations demand the substitution of these composites due to their high toxicity. In this direction, progress in coating technology has made possible to develop free-chromate corrosion inhibitors which...

The corrosion definition is not constrained to alloy and metals, but rather the term, corrosion, can likewise be stretched out to earthenware production and other nonmetallic materials. Corrosion can prompt to problems significant in furthest fields for man-factory [1]. Corrosion gets to be distinctly a standout amongst the most difficult points for researchers and the society for building. Fro...

Several works have been done and more are on the pipeline on the influence of organic compounds containing polar functions on the corrosion inhibition of metals in various aqueous media. Corrosion inhibition by such compounds is generally attributed to their adsorption on the metal/solution interface. The specific action of an inhibitor depends on the nature of its interaction with metal surfac...

Quantum chemical calculations based on density functional theory (DFT) method were performed on heterocyclic azole derivatives as corrosion inhibitors for mild steel in acid media to investigate the relationship between molecular structure of the inhibitors and the corresponding inhibition efficiencies (%). Quantum chemical parameters most relevant to their potential action as corrosion inhibit...

ID No : 113 ABSTRACT A carrier system is efficient if distinct payloads can be selectively released via different stimuli because unwanted and unspecific release can be avoided. For anticorrosion, the wanted carrier system is the one able to release its self-healing agents or corrosion inhibitors upon change of pHor/and redox-potential due to the variation of these two signals at the corroded s...

The biodegradable inhibitors, which could effectively reduce the rate of corrosion of carbon steel, were investigated by potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). The mixed-type inhibitors extracted from Eriobotrya japonica Thunb. leaf exhibited excellent inhibition performance, and the inhibition efficiency for carbon steel reached 90.0% at 298 K in hydroch...

Oil well are periodically acidized for enhancing oil flow. Inhibited hydrochloric acid is used during acidization to prevent corrosion of N80 or J55 steel. In the present work authors have surveyed literature on acidizing corrosion inhibitors and the salient features of research work carried out by the authors have also been highlighted.

The rotating cage apparatus is used in the oil industry as a simple and effective test for corrosion. The apparatus generates a large amount of flow induced corrosion and is used by researchers to design effective corrosion inhibitors. While the apparatus is used frequently, the fluid mechanics of the problem is not well understood. Importantly, there is no correct model for the shear stress pr...

The literature dealing with the electrochemical corrosion of copper and possibility of its prevention using inhibitors is examined. Inorganic compounds are investigated as well, but organic compounds and their derivatives in much greater numbers. Researches are directed to influence of compounds structure, concentration, method of application as well as media that inhibitor is used in on inhibi...
