Available in PDF, EPUB and Kindle. Book excerpt: A damage function for predicting the corrosion of galvanized steel structures by wet and dry deposition has been developed from the thermodynamics and kinetics of atmospheric corrosion chemistry. The function mathematically expresses the competing reactions for the buildup and dissolution of the basic zinc-carbonate corrosion film with exposure time. Major findings as expressed by the theoretical function are as follows: 1. During periods of surface wetness, SO2 reaching the surface reacts stoichiometrically with the zinc. 2. Rain acidity reacts stoichiometrically with the zinc. 3. The corrosion film of basic zinc carbonate is soluble in clean rain. The dissolution depends on the residence time of rain on the galvanized steel surface. 4. Deposition velocity controls the rate of corrosion of galvanized steel structures by gaseous SO2 during periods of wetness.

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.

Available in PDF, EPUB and Kindle. Book excerpt: A cornerstone reference in the field, this work analyzes available information on the corrosion resistance of zinc and its alloys both as solid materials and as coatings on steel, detailing the corrosion resistance of zinc in atmospheric, aqueous, underground and chemical environments. Corrosion Resistance of Zinc and Zinc Alloys illustrates the numerous benefits of zinc and duplex coatings and presents practical case histories of their use.

Book excerpt: This book is unique in several aspects. • It is the first comprehensive text ever written on the subject of duplex systems, which is the generic term for painted hot-dip galvanized steel. • Both the traditional batch hot-dip galvanizing process and the modern sheet galvanizing processes are covered. • The author offers a combination of practical information, which will enable the engineer to select the proper materials, and scientific background information. • The practical guidelines are backed up and supported by an impressive amount of technical and scientific discussions and justifications. • Modern surface analysis tools and recent applications are described. • The world literature on the subject matter is covered and is up to date. Duplex systems, which are based on the synergistic effect of galvanizing and painting, offer maximum protection against corrosion of steel surfaces in environments where galvanized steel alone cannot offer a sufficiently long resistance against rust formation. Since adhesion problems can be eliminated by the correct application of special paint products, and by sophisticated surface pretreatment and modern surface analyzing methods, duplex systems are nowadays used in a large number of industrial and domestic applications. Major savings can thus be achieved on materials and maintenance cost. Duplex systems serve also where colour is required, e.g. for aesthetic reasons, for enhancing visibility or for camouflaging. The author of this book has an unsurpassed experience in this field and the many case histories of successful (and unsuccessful) use of duplex systems for corrosion prevention provide a wealth of practical information. Including 108 colour illustrations, the book will be useful to a large group of industries, such as the paint, metallurgical, galvanizing, building, automotive, electrical and chemical industries.
