Establishment of Processing Technology of Nonporous Ceramic Bodies by Electrophoretic Deposition from Aqueous Suspensions

在陶瓷悬浮液的电泳沉积过程中，气泡的抑制通常是一个严重的问题，从以下三个方面进行了研究：(1)直流施加的控制，(2)衬底材料的选择，(3)悬浮液中的化学添加剂。结果表明，利用脉冲直流和钯衬底可以有效地抑制放电过程中气泡的产生。

The suppression of bubble generation, which is usually a serious problem in the electrophoretic deposition process using aqueous ceramic suspensions, was investigated in terms of the following three approaches : (1) control of DC application, (2) selection of substrate material, and (3) chemical additives to a suspension. It was demonstrated that the utilization of pulsed DC and palladium substrate could effectively suppress the bubble generation during EPD.
