Aluminum electrodeposition on a copper substrate in 1-ethyl-3-methylimidazolium chloride [EMIC]-AlCl₃, a room temperature ionic liquid, is carried out in a superconducting magnet up to 5 Tesla (T). Linear sweep voltammetry shows an increase in the deposition current, which is explained by the mass transport of reactants enhanced by magnetohydrodynamic (MHD) convection. The application of the magnetic field initiates the formation of nanocrystalline aluminum so that the brightness of the coating is improved. The preferential (2 0 0) orientation is suppressed by increasing the magnetic field intensity, which leads to random orientation in a high magnetic field, corresponding to the formation of fine grains.

在高达5特斯拉（T）的超导磁体中，在室温下离子液体1-乙基-3-甲基咪唑鎓盐[EMIC] -AlCl _3中在铜基板上进行铝电沉积。线性扫描伏安法显示沉积电流增加，这可以通过磁流体动力学（MHD）对流增强的反应物的质量传输来解释。磁场的施加引发了纳米晶铝的形成，从而提高了涂层的亮度。通过增加磁场强度来抑制优先（2 0 0）取向，这会导致在高磁场中产生随机取向，这对应于细晶粒的形成。
