Abstract

The invention is an electrophoretic casting process which produces highly dense green castings with residual liquid e.g. water below 7%, and which eliminates excessive liquid and electrode degradation. This is accomplished by careful selection of slip viscosity, utilization of an impervious casting mold set-up in which only a minor part of the mold is conducting, application of a varying voltage cycle, and moving one electrode relative to the other.
