Book Description
A systematic investigation of the effect of 23 elements on the corrosion behavior of magnesium alloys in a 3% solution of Sodium Chloride (NaCl) and in a humid atmosphere was carried out. The values of the stationary potentials and the variation of the potentials through times are determined. The purpose of this work is to make a systematic investigation of the effect of alloying additives on the corrosion resistance and electrochemical characteristics of magnesium alloys. It is very interesting to study the corrosion behavior of binary systems, not only from the theoretical standpoint, but also from the practical one, since the selection of systems for developing corrosion resistant alloys would be essentially random without these data. Reports give data about the effect of some elements on the corrosion and electrochemical behavior of magnesium alloys. However, the information in the literature about the systematic investigation of the effect of alloying components on the corrosion characteristics of magnesium alloys is inadequate. Keywords: Russian Translations.

Book Description
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. - Provides a comprehensive account of the corrosion of magnesium alloys covering fundamentals such as the corrosion electrochemistry, activity and passivity - Reviews the metallurgical effect in relation to the corrosion of magnesium alloys, including the role of micro-structure and earth-rare elements - Assesses environmental influences such as atmospheric corrosion, stress corrosion cracking, creep and fatigue behaviour, and galvanic corrosion

Book Description
Magnesium (Mg) alloys have low corrosion resistance and exhibit unusual corrosion behavior in aqueous environments. Because of this unique corrosion performance, some special corrosion prevention techniques have to be employed for Mg alloys in their applications. This chapter briefly summarizes the corrosion characteristics of Mg alloys, and also presents a strategy and methodologies to mitigate the corrosion damage of Mg alloys in applications.

Book Description
Classical magnesium alloys are a combination of aluminium, magnesium, manganese and zinc. Magnesium combined with lithium forms ultralight alloys that have many uses. Since it is a reasonable material, it offers great possibilities and is constantly tested at various angles of applications and properties. Magnesium, previously used for military purposes, seems to fit perfectly to the requirements of the currently prevailing technology. Low density with appropriate mechanical properties (strength, high operating temperature), good foundry properties (high castability and low shrinkage), vibration damping ability and cost-effectiveness of recycling seem to be an ideal response to market needs. All things considered, magnesium alloys are the perfect material used in various industries starting from the automotive industry, through sport, electronics up to the space industry and defence. This book is written by experts in various areas of magnesium science and technology. It gives a general idea of modern advancements in theory and practical purposes of magnesium alloys. The book reports fundamental aspects of corrosion types and details about magnesium alloys designed to work in elevated temperatures and superplastic behaviour. Fundamentals, broad experience, theory as well as complex technological aspects make this work helpful for engineers and scientists from all over the world.

Book Description
Anodization is one of the most important and effective surface pre-treatments for Mg alloys. This chapter systematically summarizes Mg alloy anodizing behavior, the compositions and microstructures of anodized films on Mg alloys and the anodization-influencing factors. Based on the anodizing voltage variation, gas evolution and sparking behavior in a typical anodizing process and the characteristic composition and microstructure of an anodized coating, a four-stage anodizing mechanism is postulated. Moreover, the corrosion performance of anodized Mg alloys is systematically reviewed and a corrosion model is proposed to explain the corrosion performance and electrochemical behavior. It is believed that some of the measured electrochemical features can be utilized to rapidly evaluate or compare the corrosion resistance of anodized Mg alloys.

Book Description
Magnesium (Mg) alloys, possessing good thermal and electrical conductivity, low density, recyclability, high specific strength, and excellent damping capacity, are regarded as one of the most promising light metallic materials. Mg alloys are also known as the “inexhaustible green light engineering material” compared with steel, aluminum, copper, and engineering plastics, providing some important applications in communications, automotive, defense, aerospace, and biomedical industries. However, the low electrode potential causes poor corrosion resistance in the environment of moist air, sulfur, and marine atmosphere. And thus, the corrosion and protection technology of Mg and its alloys is listed as an important research topic in this field. In this Research Topic, the latest research papers on corrosion and protection of Mg and its alloys are collected to provide a platform for researchers and readers to understand the recent developments in this field. Good use of this platform could improve the international research level in corrosion and protection of Mg and its alloys and promote the “green, safe, life-extending and smart” anti-corrosion technology and expand the application range of Mg and its alloys. High-quality Original Research and Review articles in this field are all welcome for submission to this Research Topic. Research interests include but are not limited to the following areas: • Corrosion behaviors and mechanisms • Surface treatment technology • Biodegradable medical applications • High-temperature oxidation • Inhibitors for Mg and its alloys • New monitoring, evaluation, simulation, and prediction methods
