Read or download book entitled Corrosion of Magnesium Alloys written by G L Song which was release on 25 March 2011, this book published by Elsevier. Available in PDF, EPUB and Kindle Format. Book excerpt: The use of magnesium alloys is increasing in a range of applications, and their popularity is growing wherever lightweight materials are needed. This book provides a comprehensive account of the corrosion of magnesium alloys. It covers not only the corrosion performances and mechanisms of Mg alloys in conventional environments, such as sodium chloride solutions, but also looks at their corrosion behaviours in special media, like engine coolants and simulated body fluids. Part one covers fundamentals such as the corrosion electrochemistry, activity and passivity of magnesium and its alloys. Part two then considers the metallurgical effect in relation to the corrosion of magnesium alloys, including the role of micro-structure and earth-rare elements, the corrosion behaviour of magnesium-based bulk metallic glasses, and the corrosion of innovative magnesium alloys. Part three goes on to describe environmental influences on the corrosion of magnesium alloys, such as atmospheric corrosion, stress corrosion cracking, creep and fatigue behaviour, and galvanic corrosion. Finally, part four is concerned with various means of protecting magnesium alloys against corrosion through the use of aluminium electrodeposition, conversion and electrophoretic coatings, and anodisation. With its distinguished editor and team of contributors, this book is an invaluable resource for metallurgists, engineers and designers working with magnesium and its alloys, as well as professionals in the aerospace and automotive industries.

Summary : A thin E-coating can be rapidly deposited on the surface of a Mg alloy in a cathodic E-coating bath without applying any current or potential. The selectively self-deposited coating results from the high surface alkalinity of Mg. The ‘electroless’ E-coating pre-film can offer adequate corrosion protection for Mg alloys. The ...

Summary : Magnesium and its alloys are promising materials for automotive, aerospace and bio-implant applications due to low density (1.81g/cm3), very low elastic modulus (45GPa) and high tensile yield strength (200MPa). However, they corrode too quickly in aggressive environments and possess poor wear resistance. Wear and corrosion are essentially surface dependent ...
