This book was released on 1996 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: The anti-corrosion performance of conducting polymers coated on the mild steel and stainless steel samples which exposed to artificial brine and dilute hydrochloric acid was investigated. This work attempts to rationalize the observed corrosion processes in order to elucidate protection mechanisms from the view of a corrosion engineer. A systematic correlation between the inhibition performance of electrically conducting polymers and its electronic, molecular, and electrochemical properties was also established. Experiments were conducted to evaluate the electrochemical kinetic behavior of the oxidation of metal surfaces for the purpose of understanding the interfacial stability, oxidation response and porous film diffusion phenomena of oxidation films on metal surface. Several reaction models and revised corrosion principles are presented to discuss the protective properties of intrinsically conducting polymers from electrochemical macroscopic theories and microscopic molecular details.

Download or read book Conducting Polymers polyimide clay Nanocomposite Coatings for Corrosion Protection of Aa 2024 Alloy written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Corrosion of metals is a major problem in the aerospace and automobile industry. The current methods of corrosion protection such as chromate conversion coatings are under increased scrutiny from the Environmental Protection Agency (EPA) due to their carcinogenic nature. Intrinsically conducting polymers (ICPs) like polyaniline and polypyrrole have been considered as a potential replacement for chromate conversion coatings and have been under investigation since past decade. The goal of this study is to replace the chromate conversion coating by an environmentally friendly organic coating. Poly (N-ethyl aniline) coating was electrodeposited as the primer layer and polyimide-clay nanocomposite was solution cast as the barrier layer on AA-2024 alloy. This study will provide a better understanding of the corrosion protection mechanism of the conducting polymer coating. Various characterization techniques such as infrared spectroscopy, cyclic voltammetry and scanning electron microscopy were used to study the formation, chemical structure and morphology of the coatings. Electrodeposition parameters like monomer concentration, applied current density and the reaction time were varied in order to optimize the properties of the conducting polymer coating. The corrosion performance of the primer coating was evaluated by DC polarization studies. It was found that poly (N-ethyl aniline) reduces from emeraldine to leucoemeraldine form; reducing the rate of cathodic reaction, which reduces the rate of corrosion of AA-2024 alloy. Polyimide-clay nanocomposite coating was solution cast on the conducting polymer primer layer for enhancing the barrier and corrosion properties of the coating system. The concentration of polyimide (10-25 vol %) and clay (0.1 and 1 wt %) were varied in the coating formulation to optimize the barrier properties of topcoat. X-ray diffraction showed that the intergallery clay distance decreased from 17.2[alpha] to 11.79[alpha] after immidization of polyimide-clay nanocomposite coating and infrared spectroscopy suggested that there was hydrogen bonding interaction between clay and polyimide chains. DC polarization study, electrochemical impedance spectroscopy and scanning vibrating electrode technique were used to evaluate the corrosion property and model the coating degradation in corrosive medium. It was found that the corrosion property were dependent on the thickness of the barrier coat and concentration of clay in the polyimide coating. The results obtained from the above mentioned test suggest that poly (N-ethyl aniline)/polyimide-clay nanocomposite coatings system is a potential candidate to replace the traditionally used and environmentally unfriendly chromate conversion coating.

Download or read book Developments in Corrosion Protection written by Mahmood Aliofkhazraei and published by BoD – Books on Demand. This book was released on 2014-02-20 with total page 712 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the first thing that comes to your mind after hearing the term “corrosion” is corrosion of a metal. Corrosion is a basically harmful phenomenon, but it can be useful in some cases. For instance, environment’s pollution with corrosion products and damage to the performance of a system are among its harmful effects, whereas electric energy generation in a battery and cathodic protection of many structures are among its advantages. However, these advantages are almost nothing as compared to the costs and effects imposed by its detrimental influences. The enormous costs of this phenomenon can be better understand through studying the published statistics on direct and indirect corrosion damages on economy of governments. The direct cost of corrosion is near 3 % of the gross domestic product (GDP) of USA. Considering this huge cost, it is necessary to develop and expand the corrosion science and its protection technologies.

Professor Alan MacDiarmid, 2000 Nobel Laureate, presents a brief review of the history of electroactive materials with a general understanding of the synthesis of electroactive materials and corrosion in aqueous environments. Several authors explain the phenomena of corrosion and propose mechanisms by which electroactive polymers inhibit corrosion. Several studies include current state-of-the-art synthesis of electroactive polymers, and data supporting the prevention of corrosion in various media are discussed. In addition, new techniques for measuring the onset of corrosion are presented. Chapters in this volume represent a broad range of new electroactive materials used in corrosion prevention and techniques used to measure corrosion. Both materials scientists and engineers will find this book useful for understanding and preventing corrosion. Alternatives to traditional barrier coatings used to prevent or retard corrosion are also discussed. Although previously published books have focused on organic and inorganic barrier coatings to prevent corrosion, this book focuses exclusively on electroactive polymers and their performance in retarding corrosion. Electroactive polymers represent a new, environmentally friendly approach to corrosion prevention.
