钚可以在草酸铵、硫酸铵以及氯化铵等体系中电沉积,但是在制备小面积Pu靶时,分子电沉积出现电镀层,硫酸体系电沉积阴极气泡覆盖活性区导致断电,严重影响电沉积质量。因此,开展了新的电沉积体系研究。硫酸体系是在水相电沉积体系中最为稳定,但体系中游离的氢离子较多,阴极析氢严重,直接影响镀层质量。经综合考虑,我们选定了以硫酸 Plutonium can be electrodeposited in systems such as ammonium oxalate, ammonium sulfate and ammonium chloride. However, in the preparation of small-area Pu targets, electroplating occurs on the molecular electrodeposits. Sulfuric acid system electrodeposited cathode bubbles cover the active region, Deposition quality. Therefore, a new electrodeposition system has been developed. Sulfate system is the most stable in the aqueous electrodeposition system, but more free hydrogen ions in the system, serious hydrogen evolution in the cathode, a direct impact on coating quality. After comprehensive consideration, we selected sulfuric acid
