Request a sales quoteThe Metallurgy of Zinc Coated Steels provides a comprehensive overview of the science and engineering of zinc coatings. Beginning with a look at new innovations made in the hot-dip coating methods (CGL), the book goes on to discuss phase equilibria, Zn bath phenomena and overlay coating formations. Both processing methods and controls are covered, as well as corrosion resistance and coating product properties. The book concludes with a discussion of future opportunities for zinc coatings. This book is a vital resource for both individuals new to this area while also serving as a handbook for users and producers of zinc coatings.
- Presents a basic understanding of the science and engineering behind zinc coatings with a thorough and cutting-edge look at their processing methods, controls, properties, and applications
- Discusses corrosion resistance, overlay coating formation, heat treatment, interface reactions, deposition processes, and more
- Covers real-world applications of these coatings
