Book Description
This guide represents a consensus on best industry practice for shop application of zinc rich primers to previously uncoated bridge steel and includes the proper preparation of the steel surfaces and the mixing, application, and cure of coatings. To simplify the application parameters for a system based on zinc-rich primers on new steel bridges, a series of charts have been developed. These charts provide a convenient summary listing the detailed requirements for surface preparation, environmental conditions, coating application, curing, and verification testing. The guide addresses a three-coat system consisting of primer, intermediate coat, and topcoat, but is appropriate for application of a two-coat system or primer only.

Book Description
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 Description
The 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

Book Description
This thesis investigates the properties of different coating systems to protect against corrosion for the steel substrate under environments of oil and gas. The coating systems were divided in two main parts according to compositions: the organic zinc and the inorganic zinc system. For each system, steel panels coated with only primers and samples coated with primers, intermediate coats and topcoats were tested. Electrochemical impedance spectroscopy (EIS) and open circuit potential (OCP) tests were used to investigate the performance of the coatings. On one side of each panel, a pinhole defect was introduced, and the tests were performed for 3 months. The two multilayer systems were then compared with TESLAN 1101 ZN-CNT low VOC epoxy primer along with topcoat. On the other side of the panels, the tests were run for 4 months to examine their performance with no defect. The solution used contained 2000 ppm of chloride concentration with a pH value of 3.5, and was refreshed weekly. For panels coated with primers only, the results showed that they all formed corrosion products, which protected the steel substrate as barriers. For panels coated with the multilayer systems and no defect, the electrolyte slowly penetrated into the coatings, but the coatings were still providing good protection against corrosion. The multilayer systems all performed better than primers only in terms of protecting steel, indicating the significance of topcoat. With pinholes, primers show very similar properties, while multilayer coating systems show that the existence of pinholes helped activate zinc as sacrificial metal. When comparing the multilayer systems with pinholes, the results show that the existence of carbo nanotube did not significantly improve the performance of coating. Among all the coating systems, inorganic zinc rich multilayer systems had the best protection against corrosion.
