The 電泳沉積法係利用膠體懸浮液之帶電顆 conventional shell building process, ie. dipping and 粒在直流電場作用下進行泳動沉積並聚集在 stuccoing were practiced and repeated for several 其帶相反電性之電極。由於設備簡單、低成 times, till the ceramic shell mold were obtained. 本、具高沉積速率、表面精度高等優點，目 The effects of the applied voltage and deposition 前廣泛應用於陶瓷薄膜製作。本研究擬在導 time on the deposition behaviors were examined. 電塑膠基材表面以電泳沉積方式沉積 ZrO2 The scanning electron microscope (SEM) was 面層陶殼模，待其乾燥後再反覆進行沾漿、 applied to investigate the surface morphology of 淋砂、乾燥等作業以得具一定厚度之陶殼 ZrO2 coating. Both the surface roughness of the 模，探討輸出電壓、沉積時間對 ZrO2 沉積行 ceramic shell molds made by EPD process and 為的影響，應用 SEM觀察 ZrO2 沉積層表面 conventional shell building process were measured 形態並利用表面粗度儀量測基材與陶殼模之 and compared by surface roughness tester. The 表面粗糙度，分析電泳沉積與一般傳統沾 results showed that, the ZrO2 deposit weight 漿、淋砂作業所製備之陶殼模表面品質差
