Corrosion Science And Engineering

The ability to prevent failures by managing corrosion is one of the main global challengesof the twenty-first century. However, most practicing engineers and technologists have only a basic understanding of how they can actively participate in this urgent economic and environmental issue. Now, students and professionals can turn to this newly revised edition of the trusted Corrosion and Corrosion Control for coverage of the latest developments in the field, including advances in knowledge, new alloys for corrosion control, and industry developments in response to public demand.

Corrosion Science and Engineering

This Fourth Edition presents an updated overview of the essential aspects of corrosion science and engineering that underpin the tools and technologies used for managing corrosion, enhancing reliability, and preventing failures. Although the basic organization of the book remains unchanged from the previous edition, this new update includes:

Expanded discussions on electrochemical polarization, predicting corrosion using thermodynamics, steel reinforcements in concrete, and applications of corrosion control technologies in automotive, nuclear, and other industries

Complemented with numerous examples to help illustrate important points, Corrosion and Corrosion Control, Fourth Edition enables readers to fully understand corrosion and its control and, in turn, help reduce massive economic and environmental loss. It is a must-read for advanced undergraduates and graduate students in engineering and materials science courses, as well as for engineers, technologists, researchers, and other professionals who need information on this timely topic.

Solving the problem of corrosion could save the oil and gas industry billions. According to The TWI, corrosion and the mitigation of corrosion sets the sector back $1.4 billion (1.07 billion) each year, which means graphene has the potential to revolutionise the industry and save it a small fortune.

Self-assembled monolayers of octadecanethiol (ODT) have previously shown to provide excellent corrosion inhibition on copper exposed to humidified air containing formic acid, mimicking indoor atmospheric corrosion. ODT layers are, however, much less efficient corrosion inhibitors for zinc. In this work, we elucidate the possibility of using ODT monolayers to inhibit corrosion of brass. Based on a quantitative analysis of corrosion products, we found that ODT provides equally good corrosion inhibition of single-phase Cu20Zn as of pure copper, retarding the transportation of corrosion stimulators to the brass surface. On double-phase Cu40Zn, however, local galvanic effects led to less efficient corrosion inhibition and more corrosion products than on Cu20Zn.

This doctoral thesis explores the copper corrosion inhibiting properties of a number of nitrogen containing hetero-organic compounds in refined mineral oil. Traditional organic corrosion inhibitors, as well as novel and bioorganic compounds have been studied.

The possibility of utilising bio-organic substances as organic corrosion inhibitors has been examined. The copper corrosion inhibiting effects of four bioorganic compounds; adenine, purine, cysteine and histidine were studied by in situ ellipsometry, copper dissolution, and a standardised industrial corrosion test developed by the International Electrotechnical Commission (IEC 62535). Adenine and purine were found to adequately mitigate copper corrosion, while cysteine and histidine were found to have low, or even accelerating, effects on the corrosion rate.

The corrosion inhibiting properties of five benzo-fused azoles; benzotriazole, benzimidazol, indole, benzothiazole and benzothiadiazole in refined mineral oil were analysed by means of ellipsometry, ToF-SIMS, copper dissolution studies and the standardised industrial corrosion test (IEC 62535). It was demonstrated that copper corrosion was mitigated by the addition of benzotriazole and benzimidazole. However, addition of indole, benzothiazole and benzothiadiazole did not generate any significant corrosion mitigating effect. In general, the corrosion inhibition efficiency of the investigated molecules was found to decrease with increased polarizability of the molecule. 041b061a72
