Reduction electrode for the deposition of metal on an object with a metallized surface by an oxido-reduction reaction, notably for coating micro-spheres for a range of micro-component applications

摘要

A reduction electrode (11) is used for the deposition of metal on an object which is metallized on a surface. It incorporates a cavity (23) enclosing the object during the deposition and has a geometry assuring free movement to the object. The cavity is delimited by a wall incorporating an opening (25) communicating the inside of the cavity with a deposition solution in which the electrode is plunged during deposition. Independent claims are also included for : (A) a method for the deposition of metal by an oxy-reduction reaction; (B) a device for putting this method of deposition into operation.
