This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: During oil and gas production and transportation, the presence of an oil-sand slurry, together with the presence of CO2, H2S, oxygen, and seawater, create an erosive/abrasive and corrosive environment for the interior surfaces of undersea pipelines transporting oil and gas from offshore platforms. Erosion/wear and corrosion are often synergic processes leading to a much greater material loss of pipeline cross-section than that caused by each individual process alone. Both organic coatings and metallic sacrificial coatings have been widely employed to provide protection to the pipeline steels against corrosion through barrier protection and cathodic protection, and these protection mechanisms have been well studied. However, coating performance under the synergic processes of erosion/wear and corrosion have been much less researched and coating degradation mechanisms when erosion/wear and corrosion are both going on has not been well elucidated.In the work presented in this dissertation, steel panels coated with filler reinforced epoxy coatings and carbon nanotubes (CNTs) reinforced zinc-rich coatings have been evaluated under erosion/wear followed by an exposure to a corrosive environment. Electrochemical tests and material characterization methods have been applied to study the degradation mechanisms of the coatings during the tests and coating degradation mechanisms have been proposed.While organic coatings with a lower amount of filler particles provided better protection in a corrosive environment alone and in solid particle impingement erosion testing alone, organic coatings with a higher amount of filler particles showed better performance during wear testing alone. A higher amount of filler particles was also beneficial in providing protection against wear and corrosion environment, and erosion and corrosion environment. Coating thickness played a significant role in the barrier properties of the coatings under both erosion and corrosion tests. When the organic coatings were exposed to a corrosive environment with presence of H2S, thicker coatings provided better protection regardless of the amount and types of filler particles present in the coatings. For zinc-rich coatings, coatings with CNTs provided better barrier protection for the steel substrate than traditional zinc-rich coatings in a corrosive environment alone. However, the CNTs-filled zinc-rich epoxy coatings did not provide adequate protection when the coated specimens were exposed to erosion and corrosion.

Download or read book Atmospheric Corrosion written by Christofer Leygraf and published by John Wiley & Sons. This book was released on 2016-06-07 with total page 509 pages. Available in PDF, EPUB and Kindle. Book excerpt: ATMOSPHERIC CORROSION Presents a comprehensive look at atmospheric corrosion, combining expertise in corrosion science and atmospheric chemistry Atmospheric corrosion has been a subject of engineering study, largely empirical, for nearly a century. Scientists came to the field rather later on and had considerable difficulty bringing their arsenal of tools to bear on the problem. Atmospheric corrosion was traditionally studied by specialists in corrosion having little knowledge of atmospheric chemistry, history, or prospects. Atmospheric Corrosion provides a combined approach bringing together experimental corrosion and atmospheric chemistry. The second edition expands on this approach by including environmental aspects of corrosion, atmospheric corrosion modeling, and international corrosion exposure programs. The combination of specialties provides a more comprehensive coverage of the topic. These scientific insights into the corrosion process and its amelioration are the focus of this book. Key topics include the following: Basic principles of atmospheric corrosion chemistry Corrosion mechanisms in controlled and uncontrolled environments Degradation of materials in architectural, transport, and structural applications; electronic devices; and cultural artifacts Protection of existing materials and choosing new ones that resist corrosion Prediction of how and where atmospheric corrosion may evolve in the future Complete with appendices discussing experimental techniques, computer models, and the degradation of specific metals, Atmospheric Corrosion, Second Edition continues to be an invaluable resource for corrosion scientists, corrosion engineers, conservators, environmental scientists, and anyone interested in the theory and application of this evolving field. The book concerns primarily the atmospheric corrosion of metals and is written at a level suitable for advanced undergraduates or beginning graduate students in any of the physical or engineering sciences.

Download or read book Corrosion and Electrochemistry of Zinc written by Xiaoge Gregory Zhang and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humankind's use of zinc stretches back to antiquity, and it was a component in some of the earliest known alloy systems. Even though metallic zinc was not "discovered" in Europe until 1746 (by Marggral), zinc ores were used for making brass in biblical times, and an 87% zinc alloy was found in prehistoric ruins in Transylvania. Also, zinc (the metal) was produced in quantity in India as far back as the thirteenth century, well before it was recognized as being a separate element. The uses of zinc are manifold, ranging from galvanizing to die castings to electronics. It is a preferred anode material in high-energy-density batteries (e.g., Ni/Zn, Ag/Zn, ZnJair), so that its electrochemistry, particularly in alkaline media, has been extensively explored. In the passive state, zinc is photoelectrochemically active, with the passive film displaying n-type characteristics. For the same reason that zinc is considered to be an excellent battery anode, it has found extensive use as a sacrificial anode for the protection of ships and pipelines from corrosion. Indeed, aside from zinc's well-known attributes as an alloying element, its widespread use is principally due to its electrochemical properties, which include a well-placed position in the galvanic series for protecting iron and steel in natural aqueous environments and its reversible dissolution behavior in alkaline solutions.

Book excerpt: Presentation slides from the year 2017 in the subject Chemistry - Materials Chemistry, grade: 0.9, Srinivas School of Engineering, language: English, abstract: This presentation deals with organic inhibitors on the corrosion of steel and zinc.In the19th century, as the result of technological innovations, revolution in the industry, advancement in the science field, there was a growth in agricultural, industrial production, economic expansion and tremendous changes. People have changed the way of manufacturing processes during this time. All the hand works shifted to the machines. As a result of this revolution, the products were quite cheaper. Mild steel and zinc are very active in the presence of aggressive environment. In the presence of moisture and air, they give respective oxide. It results in the deterioration of metals take place that results in the failures in the industrial equipment in oil industries, gas industries, and water circulating cooling systems. These are main disadvantages of mild steel and zinc. The cause of corrosion of mild steel and zinc and the corrosion control is having critical fundamental, industrial and academic concern .In the existed literature various type of various research groups developed inhibitors. The developed inhibitors, few of them satisfied all the requirements of the industries and society. Even though they are toxic in nature, they aren’t showing inhibition at high temperature. In addition, no one has discussed complete mechanism of corrosion inhibition. In the present study, more attention is given to developing eco-friendly inhibitors. The complete mechanism of inhibition action of these inhibitors were evaluated by using practical and theoretical studies like weight loss, polarization, impedance, activation parameters, thermodynamic parameters. Scanning electron microscope is used to do morphological studies of the inhibitor. The quantum chemical studies are carried out to correlate the theoretical studies with experimental work of corrosion inhibitors. All the results were agreeing with each other. All the developed inhibitors find applications in industries.
