Song and Xu [75] studied AZ31 sheet because it is currently one of the most promising candidate materials for the closure inners in some vehicles. In the automobile industry, a Mg-base metal part must undergo various mechanical and chemical surface treatments, heat treatments and mechanical deformations. Figure 3.27 presents the influence on corrosion behaviour (as characterised by hydrogen evolution) of the following surface conditions (i)... 

Various studies have been devoted to the analysis of the anodic passivation behaviour of Mg-based metallic glasses in strong alkaline environments. Under those conditions the main alloying element Mg is spontaneously passive forming a dense and stable hydroxide layer. This is also determining for the behaviour of Mg-based glasses [59,61,64,66].

In summary, these first reported studies already clearly indicate that the corrosion stability of Mg-based metallic glassy alloys is generally low in chloride-containing aqueous solutions. Further significant modifications in alloy design and optimization of preparation conditions will be necessary to overcome this critical problem.

Another potential instrument available for risk management by metal market participants (among others) is some form of commodity index. The MG Base Metal Index (MGMI), a consumption-weighted price index based on the six LME traded metals, was introduced in early 1989 but lasted only until 1S>91." It was intended to provide a hedging facility for exposure in the commodity swaps market. However, partly due to design problems, it failed... 

Protective coatings are widely developed and used for many high temperature materials. Development of coating systems seems to be the most viable method to overcome the interaction between the continuous fibre and the matrix and the degradation of composite materials in aggressive environments. However, current efforts on this aspect are not adequate for oxidation protection, though some surface treatment techniques have been established and applied to A1 or Mg based metal matrix composites to protect them against corrosion attack in aqueous environments. 

Whilst carboxylic acids are readily available and inexpensive, they are relatively weak extractants and have not found much use in the recovery of base metals until recently when Versatic 10 has been piloted for the separation of Ni from Mn and Mg (Section 9.17.5.4). As with the phosphorus(V) acid extractants, the propensity for association leads to substantial levels of solvation of caboxylato...

As in the case with PAFC s, voltage obtained from an AFC is affected by ohmic, activation, and concentration losses. Figure 4-7 presents data obtained in the 1960 s (18) which summarizes these effects, excluding ohmic losses, for a catalyzed reaction (0.5-2.0 mg noble metal/cm ) with carbon-based porous electrodes for H2 oxidation and O2 reduction in 9 N KOH at 55-60 C. The electrode technology was similar to that employed in the fabrication of PAFC electrodes. Performance of AFC s with carbon-based electrodes has not changed dramatically since these early results were obtained.
