Magnesium alloy ability

To date, research efforts regarding protective thin films have primarily focused on compact textures. In fact, smdies have confirmed that mesoporous thin films could confer corrosion protection for magnesium alloys. Furthermore, a mesoporous structure is beneficial to the integrity of the outer surface. This mesoporous structure could effectively release stress in the thin film and ameliorate the mismatch between the substrate and coating thus, crack-free thin films can be successfully prepared. In addition, smdies have reported that mesoporous thin films can easily induce apatite formation and have high bone-forming ability owing to the enhancement of cell activity and protein adsorption. ... 

Because of their low density these alloys are attractive for use where weight is at a premium. The major drawback to the use of these alloys is their ability to ignite in air (this can be a problem in machining) they are also costly. Magnesium alloys are used in both the wrought and die cast forms, the latter being the most frequently used form. 

PANI/Ti02 nanocomposites have been also used by Sathiyanarayanan et al. to protect magnesium alloy from corrosion [318]. The ability of the PANI/T1O2 nanocomposite coating to protect against corrosion was found to be more than that of the pure RANI coating, because the uniform distribution of PANI can protect the metal surface more uniformly [318].

The ability of silane coatings modified with cerium ions to inhibit corrosion activity was also tested, with success, for magnesium alloys [65]. AZ31 Mg alloys coated with a silane layer containing cerium ions revealed improved corrosion performance in electrochemical impedance tests. Furthermore, SVET measurements also showed... 

Aluminum Aluminum alloys have unusual ability to maintain strength and shock resistance at temperatures as low as —250°C (—425°F). Good corrosion resistance and relatively low cost make these alloys very popular for low-temperature equipment. For most welded construction the 5000-series aluminum alloys are widely used. These are the aluminum-magnesium and aluminum-magnesium-manganese materials. 

The ability of certain compositions containing magnesium or magnalium alloy to burn in a pulsing, strobe light manner is a novel phenomenon believed to involve... 

Malleability the ability of a material to be permanently deformed with ease, as in forging, rolling, or extruding. Aluminum, copper, and magnesium have outstanding malleability and can impart this characteristic to their alloys. 

This chapter provides an overview of the corrosion mechanisms of typical Mg alloys, most of which contain two or more phases. Magnesium (Mg) is a reactive metal and corrosion protection is an issue of importance [1] particularly for the automobile industry. The rapid increase in Mg use is due to its lightweight and good casting capabilities, particularly its ability to be diecast into large, thin sections. Typical examples are automobile seats, instrument panels, computer cases, etc. Reviews [1-4] and our early research [5-9] have indicated that the poor corrosion resistance of Mg alloys results from (a) the high intrinsic dissolution tendency of magnesium, which...
