Available in PDF, EPUB and Kindle. Book excerpt: A model for corrosion of zinc based on competing mechanisms of the formation and dissolution of a protective film of basic zinc carbonate was evaluated. The model consists of a diffusivity term (ions through the film) which controls the buildup of a protective film and a solubilization term which controls the rate of dissolution of the film. The model was evaluated by using comprehensive data collected from field experiments designed to separate the effects of wet and dry acid deposition from normal weathering effects such as clean rain, temperature, wind speed, and relative humidity. These data were used primarily to evaluate the theoretically calculated components of the dissolution rate term because after about three years it becomes the rate upon which long-term corrosion behavior may be predicted. The model was also evaluated with respect to historical long-term data for different shapes and sizes of galvanized products.

Download or read book Corrosion and Electrochemistry of Zinc written by Xiaoge Gregory Zhang and published by Springer Science & Business Media. 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.

Download or read book Duplex Systems written by J.F.H. van Eijnsbergen and published by Newnes. This book was released on 2012-12-02 with total page 223 pages. Available in PDF, EPUB and Kindle. 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.
