对传统的化学镀银工艺进行了改进,化学镀银层质量与、镀膜温度、还原剂的加入方式以及膜面积与镀液加液量之比有着密切的关系。实验结果表明控制镀膜温度（20℃以下）,采用间歇式加入N2H4的方式并且增大膜面积与镀液加液量之比,这样容易控制反应速度,不易使银沉积在镀槽壁上,有利于获得厚度均匀平整、有光泽、附着力强的银/陶瓷复合膜。%In the work,the traditional electroless plating was improved and silver/ceramic composite membrane was fabricated.Plating quality has close relation with plating temperature,addition modes of reducing agents,the ratio between membrane area and bath amount,and so on.In the work,bright-homogeneous silver/ceramic composite membrane was prepared by keeping lower temperature.Besides,batch type addition of N2H4 and increasing the ratio between membrane area and bath amount were employed.Under above conditions,reaction rate was well controlled to avoid silver deposition on the tank.
