Abstract

An apparatus and method for coating at least one substrate with an alumina hydrate film includes a coating vessel for containing a caustic coating solution, and at least one support within the coating vessel upon which are mounted substrates and porous containers. The porous containers hold aluminum metal for reacting with the caustic coating solution. A partition is situated between the porous containers and the substrates, which partition separates the gas bubbles produced by the reaction of the aluminum metal and the caustic coating solution from the substrates and which partition prevents the gas bubbles from contacting the substrates.
