In electroforming metal is deposited electrolytically upon the cathode-polarized electrode of an electrochemical cell. Unlike electroplating in which the deposited metal has to adhere to the cathode after electrolysis, in electroforming much thicker coatings are applied, the plating is performed on a cathode, and the surface of which bears a nonconducting film so that the deposited metal can be subsequently removed to yield a free-standing artifact or structural component.
Theory and Application
Electroforming was discovered by Jacobi in Russia in 1838. During his investigations of galvanic cells, he used an engraved copper printing plate as the cathode with a copper sulfate solution and electrodeposited copper upon it. Although he had difficulty separating the electrodeposit from the engraved printing plate, the deposit had accurately reproduced the details engraved in the original plate. In 1842, Boettger of...
