EPD is a ceramic processing technique which has been used to fabricate ceramic–CNT composite films and coatings. 109 EPD is achieved by motion of charged particles toward an electrode dispersed in a suitable solvent under an applied electric field.
ادامه مطلبAfterward, they are shaped and cut to precise requirements and fired at extreme heat in temperature-controlled kilns. Firing removes the moisture and binders. With additional firing, powder particles are sintered together and the products shrink due to reduced porosity. This process results in products of extreme density and hardness.
