ABSTRACT:
One aspect of the invention is a method for incorporating carbon homogeneously into aluminum materials. The first step is to apply a positive charge to molten aluminum. Next, a negative charge is applied to an organic compound. Under an inert atmosphere, the negatively charged organic compound is mixed with the positively charged molten aluminum while running electric current therethrough. An aluminum material with carbon homogeneously dispersed throughout is recovered.
