在铅的薄层电沉积生长中,铅的枝晶沉积物由于氢气的扰动从阴极断裂.断裂的沉积物片段并非在薄层电解槽中保持不动,而是自发地朝阳极方向快速运动.研究表明,这种奇特的现象是由断裂沉积物两端发生的共轭溶解-沉积反应造成的.本文讨论了这种现象产生的机制.
During the electrodeposition of lead, the dendrite deposit segregates from the cathode due to the disturbance of hydrogen gas. The segregated deposit could move toward the anode spontaneously rather than keep stationary. The studies show that this novel phenomenon was caused by the conjugate electrodissolution and electrodeposition reactions taking place at two ends of the isolated segment of the deposit. The mechanism inducing this phenomenon is suggested.
