采用有机溶剂体系在紫铜基体上电沉积制备Al–碳纳米管(CNTs)复合镀层。镀液组成为：LiAlH410 g/L，四氢呋喃600 mL/L， AlCl3100 g/L，甲苯400 mL/L，柠檬酸钠20 g/L，分散剂0.4 g/L，CNTs 1 g/L。研究了电流密度、温度、搅拌速率和电镀时间对电沉积Al–CNTs复合镀层的影响，得到较好的工艺条件为：电流密度6 A/dm2，温度25°C，搅拌速率300 r/min，时间40 min。在该工艺条件下制备的Al–CNTs复合镀层呈较光亮的灰白色，厚度约为30μm，镀层的微观表面凹凸不平，但晶粒比纯Al镀层更为细致。
採用有機溶劑體繫在紫銅基體上電沉積製備Al–碳納米管(CNTs)複閤鍍層。鍍液組成為：LiAlH410 g/L，四氫呋喃600 mL/L， AlCl3100 g/L，甲苯400 mL/L，檸檬痠鈉20 g/L，分散劑0.4 g/L，CNTs 1 g/L。研究瞭電流密度、溫度、攪拌速率和電鍍時間對電沉積Al–CNTs複閤鍍層的影響，得到較好的工藝條件為：電流密度6 A/dm2，溫度25°C，攪拌速率300 r/min，時間40 min。在該工藝條件下製備的Al–CNTs複閤鍍層呈較光亮的灰白色，厚度約為30μm，鍍層的微觀錶麵凹凸不平，但晶粒比純Al鍍層更為細緻。

Al–carbon nano-tube (CNT) composite coating was prepared on pure copper substrate from an organic solvent system composed of 10 g/L LiAlH4, 600 mL/L tetrahydrofuran, 10 g/L AlCl3, 400 mL/L methylbenzene, 20 g/L sodium citrate, 0.4 g/L dispersant, and 1 g/L CNTs. The effects of current density, temperature, stirring rate, and electrodeposition time on electrodeposition of Al–CNTs composite coating were studied. The optimal process conditions were obtained as follows:current density 6 A/dm2, temperature 25 °C, stirring rate 300 r/min, and electrodeposition time 40 min. The Al–CNTs composite coating obtained under the given conditions is brightly gray-white with a thickness of ca.30μm, featuring uneven microscopic surface and finer and more compact grains as compared with pure Al coating.
