Development of low temperature processes for electrochemical deposition
of aluminium is highly desirable in order to overcome high energy cost, toxic emission of
fluoride and chloride from high temperature molten salt electrolytes. AlCh+urea ionic
mixture known as deep eutectic solvent (DES) is recognized as an economical electrolyte for
alunuruum electrodeposition at room temperatures [I, 2]. Electrodeposition experiments were
conducted on aluminum electrode using constant deposition current density (2 mA cm"2
) at
different bath temperatures: 25 °C, 35°C and 50°C. Using SEM and EDS techniques the
deposits were studied for their morphology dependence on the experimental conditions.
particularly working temperature. Electrochemical techniques used were linear sweep
voltarnmetry and chronopotentiometry. The size of individual Al grains deposited under the
same constant current density became larger (from nanometers to micrometers) with
increasing bath temperature. The shape ...of deposits ranged from regular crystal grains to complicated morphology including needle-like and flake-like structures.
