Abstract
Electrodeposition of aluminum on metal at low temperatures, with the participation of the ionic liquid electrolyte will contribute to solving many technical issues in critical industries such as automobiles, aircraft, electronics ... the industry uses aluminum and aluminum coated materials most.Using ionic liquids based on choline chloride and urea to electrodeposition of aluminum is more published in scientific journals in the world. In this article, we present the preliminary results of electrodeposition of aluminum on cathodes as copper, iron and especially glassy carbon. The nature of electrolytes based on choline chloride and urea were analyzed and identified. The solubility of aluminum chloride in this mixture also surveyed. The results showed that only choline chloride mixture / urea with a mole ratio of 1:1 solution is to create transparent and recrystallized at room temperature. The nature of electrolytes based on choline chloride and urea were analyzed and identified. The solubility of aluminum chloride in this mixture also surveyed. The results showed that only choline chloride mixture / urea with a mole ratio of 1:1 solution is to create transparent and recrystallized at room temperature. Solubility of aluminum chloride in this system is 5% by weight. So in the study of aluminum deposited on the cathode, we use only liquid choline chloride / urea / AlCl3 at the rate of 1 mol / 1 mol + 5% by weight of AlCl3. The electroplating are made with temperatures from 90-120 ° C, the time is 2 hours. Distance between two poles is 2 cm, the maximum of surface area 3 cm2 voltage between the two poles from 1-3 V and amperage stable at 100 - 150 mA. Nitrogen environment are set to limit the influence of oxygen and hydrogen. The results of the analysis on the cathode structure of aluminum films by XRD, SEM, XRF, EDS ... showed similarities with the aluminum anode. The purity of the aluminum film obtained depending on the materials used as the cathode. The purity of aluminum on the GC-cathode is 92.42 % atom, on iron is 70.33 % atom and on copper is 82.63 % atom.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
