Abstract:
Aluminum and aluminum-magnesium alloys were prepared by direct current electrodeposition and pulse electrodeposition in AlCl3-LiAlH4-benzene-tetrahydrofuran (THF) system. Electrochemistry experiment was conducted by three electrode system and the cyclic voltammetry and chronamperometric graphs were studied. The surface morphology, composition, and content of the aluminum and the aluminum- magnesium alloys were studied by using scanning electron microscope (SEM) and energy spectrum (EDS). Results show that the coating of aluminum and the aluminum magnesium are superior when the pulse duration ratio (ton:toff) is 0.08s:0.02s. The coatings are best when DC deposition current density is 14.89mA/cm2. SEM shows that the grains size is thick and the surface is rough by DC deposition. But the coatings obtained by pulse electrodeposition are more uniform and thinner than the coatings obtained by DC deposition and the surface is flatter.
