Pre-proposal abstract

Magnesium base alloys obtained by ultra rapid solidification have shown interesting phenomena such as the appearance of some new type of quasicrystalline and nanocrystalline structures as well as special electrochemical characteristics for application in the energy conversion field. They can be directly used to produce galvanic cell anodes due to high compositional and structural homogeneity, to cooling rates that assure rapid stabilization of electrode potential and an anticorrosive resistance maximization.

The classical alloys have the disadvantage of non-homogeneity, unavoidable with materials produced by conventional metallurgical operations, which also exhibit a low corrosive resistance. Production of anodes made of these materials by conventional technologies involves costly stages, i.e. melting, casting, extrusion, rolling and intermediary heat treatments

The properties of the alloys obtained by ultra rapid solidification seem to open new ways to magnesium base alloys direct application in the industry and in the energy conversion field. One expects favorable results from these new alloys as regards the grain size modification and the homogeneity of the material which has as a consequence the improvement of the mechanical properties 1, as well as the corrosion resistance.

The advantages of the ultra rapid solidification are reflected by the favorable modification of the material properties, possible to associate with economic advantages.

This new type of alloys offer a wide range of application. They can be used in obtaining autonomous electric power sources for the beckoning and failure warning systems in which sea-water is used as an activating factor. They can also be used for self-reliant power sources for transmitters in case of sea catastrophes or as generators in military devices.

The advantages of this new approach are:

The cells having Mg-base alloy ribbon anodes with quasicrystalline and nanocrystalline structures can be produced with a wide range of chemical compositions, with a high power generation rate, due to the high anode specific surface area. They allow dimensional reduction of cells in sea-water activation, as well as lowering of production costs.
