Electrochemical Co-Deposition of Alloying Elements during Aluminium Electrolysis in a Laboratory Cell
Awayssa, Omar Ratib (Doctoral theses at NTNU;2021:121, Doctoral thesis, 2021)Aluminium alloys are mainly produced by the so-called melt mixing at which an alloying element is added to the molten aluminium before casting. This approach suffers from several drawbacks such as the high requirements of ... -
Electrochemical Production of Al-Si Alloys in Cryolitic Melts in a Laboratory Cell
Awayssa, Omar Ratib; Sævarsdottir, Gudrun; Meirbekova, Rauan; Haarberg, Geir Martin (Peer reviewed; Journal article, 2021)Direct production of aluminium-silicon alloy during aluminium electrolysis in fluoride-based melts was studied.
