| 摘 要： | 主要对AlCl3和LiAlH4溶于四氢呋喃有机体系镀层的表面形貌、电镀参数、温度以及镀层的厚度进行了研究.结果表明:当电流密度或电压低时,核密度低,形变能是控制颗粒形状的主要因素,析出铝颗粒呈碟状;当电流密度或电压高时,核密度高,表面能成为主导因素,铝颗粒呈球状.实验结果还表明,电流密度或电压是影响形核密度和颗粒形貌的关键因素.采用此方法可以获得平滑、光亮、致密与基体附着良好的镀层.

| Abstract: | Electrodeposition of aluminum in an organic electrolytic system,which dissolves AlCl3 and LiAlH4 in THF solution,was studied.The effects of electrodeposition parameters,such as morphology of membrane,temperature,thickness of the coating are investigated.The result shows that lower current density or voltage produces lower nuclear density and disc-like grain.At this stage the strain energy inside the particle is the main cause of controlling the particle shape.However,with higher current density or voltage,the particles are of higher nuclear density,sphere-like grain,indicating that the surface energy is the main influential factor.The results shows that current density or voltage is the critical factor influencing nuclear density and morphology of particles.The compact and smooth aluminum coating with good adhesion and brightness can be obtained in this technology. |
