Gold plating using DMH as complexing agent and its application to hohlraum target
Gold plating using DMH as complexing agent has been applied to hohlraum target. The effects of bath compositions and operating conditions on gold plating quality were investigated by scanning electron microscopy and coulometric measurement. The results show that the gold plating bath is stable. Uniform and compact gold deposits are formed in the bath containing 8 g/L gold salt and 80 g/L DMH at the cathode current density of 1.5 A/dm2, pH level of 9-10 and bath temperature of 45 ℃.
