Effect of thermally induced relaxation on passivity and corrosion of an amorphous Al–Co–Ce alloy

Insights on the Role of Copper Addition in the Corrosion and Mechanical Properties of Binary Zr-Cu Metallic Glass Coatings

“…The mechanical properties of our Zr-Cu glassy coatings ( Figure 9) confirm that lower free volume density enhance the hardness and Young's modulus as a function of copper content [35,36]. Therefore, the free volume seems to have an effect on the mechanical properties of metallic glass [37], while on corrosion resistance this effect has not yet been elucidated in prior studies [38]. Poor passivation of Zr 48 Cu 36 Ag 8 Al 8 glassy alloy due to active dissolution of Cu was reported for a high-energy metastable state with a relatively high amount of free volume [39].…”

Electrodes Based on Amorphous Metallic Aluminum Alloys in the Reactions of Hydrogen Release

“…The amorphous metallic alloys (AMA) exhibiting high corrosion resistance within a broad range of рН values are of especial interest as catalysts of hydrogen release. It is also important to study the accumulation of hydrogen on the cathode accompanied by the formation of metal hydrides.The properties of the AMA are determined by the nature of the base metal and by the composition of alloying admixtures [7][8][9]. Thus, changing the elemental composition of AMA, one can extend the field of their applicability.…”

“…The amorphous metallic alloys based on aluminum and alloyed with transition and rare-earth metals (REM) exhibit their catalytic action in various redox processes, preserving at the same time their high corrosion resistance [8,9]. It is known that the high corrosion resistance in various media is guaranteed by the transition of…”

“…Amorphous alloys based on aluminum are used as corrosion-resistant coatings and structural materials. The AMA are corrosion-resistant in media whose рН value is close to neutral but electrodes based on Аl dissolve in strong alkaline and acidic aqueous solutions as a result of which hydrogen is released [9]:The amorphous metallic alloys based on aluminum and alloyed with transition and rare-earth metals (REM) exhibit their catalytic action in various redox processes, preserving at the same time their high corrosion resistance [8,9].
