Durability and Corrosion of Aluminium and Its Alloys: Overview, Property Space, Techniques and Developments

“…Some abridged information regarding the role of Li upon corrosion is included here. In Li rich alloys, the formation of strengthening phase, Al 3 Li which is dispersed homogeneously throughout the matrix, is responsible for the increase in strength (Lavernia and Grant 1987). It is however detrimental to corrosion as Al 3 Li initially form along the grain boundaries.…”

Self-healing coatings

“…The layer is often considered expendable or sacrificial compared to the substrate, meaning that coating life is less than the life of the underlying structure. Alternatively, it may have sacrificial components such as Mg-rich primers, where the Mg acts as cathodic protection to the underlying metal [13][14][15], or soluble corrosion inhibitors [6,12] or bioinhibitors [11]. Typically, many environments are largely benign, but increasingly coatings are being applied in more extreme applications, including deep undersea, at elevated temperatures, in caustic environments, and in space applications [7,16].…”
