摘要：
Aluminum and aluminum-magnesium alloys were prepared by direct current electro-deposition and pulse electro-deposition in AlCl3-LiAlH4-benzene-tetrahydrofuran (THF) system. Electrochemistry experiment was conducted by three electrode system and analyzed by Chronoamperometic plots. The surface morphology, composition and content of aluminum and aluminum magnesium alloys were studied by scanning electron microscope (SEM) and energy spectrum (EDS). The results show that the coatings of aluminum and 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 in 14.89mA/cm2. SEM shows that by DC deposition the grain sizes are thick and the surface is rough. But the coatings obtained by pulse electro-deposition are more uniform, thinner and the surface is flatter than obtained by DC deposition.
