Electrophoretic deposition apparatus

An apparatus for use in the electrophorectic deposition of a cup-shaped body from a slurry, comprising:

• a chamber constituting a first electrode and having a slurry inlet disposed at a lower end of said chamber, a first slurry outlet disposed at an upper end of said chamber and a second slurry outlet disposed at said lower end of said chamber;
• a mandrel constituting a second electrode and having an outer surface and being mounted in said chamber to define a space between said outer surface of said mandrel and an inner surface of said chamber, said first slurry outlet being disposed at an upper end of said space and surrounding said mandrel, and said second slurry outlet being disposed below a bottom face of said mandrel and having a mouth extending over substantially the whole area of said bottom face of said mandrel;
• and
• mesh member mounted over said mouth of said second outlet for controlling a flow of slurry from said slurry inlet to said first and second slurry outlets to achieve a substantially uniform slurry flow rate over all surfaces of said mandrel on which said cup-shaped body is to be deposited.
