Corrosion of Nickel-Based Alloys
Description
An authoritative account of the history, metallurgy, and corrosion behavior of nickel-based alloys
In Corrosion of Nickel-Based Alloys, a distinguished corrosion engineer and scientist delivers a comprehensive source of information on the history, metallurgy, and corrosion behavior of nickel-based alloys. The book combines fundamental knowledge of the metallurgy, chemistry, and electrochemistry relevant to these alloys with practical applications of these alloys in the area of corrosion.
Readers will learn to apply contemporary corrosion mechanisms and metallurgy in the selection and evaluation of these alloys. The author discusses corrosion models and their application to the development and assessment of Ni-base alloys.
Corrosion of Nickel-Based Alloys also includes:
- A thorough introduction to nickel alloys used in the nuclear, chemical, oil and gas, marine, biomedical, and aerospace industries
- Comprehensive explorations of nickel alloys used in waste treatment and pollution control systems
- Practical discussions of the corrosion behavior of nickel-base alloys in aqueous and non-aqueous environments
- Modeling approaches that augment experimental findings
Perfect for metallurgical, mechanical, chemical, nuclear, petroleum, and petrochemical engineers, Corrosion of Nickel-Based Alloys will also benefit students and engineering consultants interested in corrosion-resistant alloys.
