FORMING AN OXIDE LAYER ON A FLAT CONDUCTIVE SURFACE

摘要

A method and apparatus for electrochemically forming an oxide layer on a flat conductive surface which involves positioning a working electrode bearing the flat conductive surface in opposed parallel spaced apart relation to a flat conductive surface of a counter electrode such that the flat conductive surface of the working electrode and the flat conductive surface of the counter electrode are generally opposed, horizontally oriented, and define a space therebetween. A volume of organic electrolyte solution containing chemicals for forming the oxide layer on the flat conductive surface of the working electrode is arranged to flood the flat conductive surface of the counter electrode surface and to occupy the space defined between the flat conductive surface of the working electrode and the flat conductive surface of the counter electrode such that at least the flat conductive surface of the counter electrode is in contact with the organic electrolyte solution and substantially only the flat conductive surface of the working electrode is in contact with the organic electrolyte solution. An electric current flows between substantially only the flat conductive surface of the counter electrode and substantially only the flat conductive surface of the working electrode, in the organic electrolyte solution, for a period of time and at a magnitude sufficient to cause the chemicals to form the oxide layer on the flat conductive surface of the working electrode.

1. A method of electrochemically forming an oxide layer on a flat conductive surface, the method comprising:
positioning a working electrode bearing the flat conductive surface in opposed parallel spaced apart relation to a flat conductive surface of a counter electrode such that said flat conductive surface of said working electrode and said flat conductive surface of said counter electrode are generally opposed, horizontally oriented, and define a space therebetween; causing a volume of organic electrolyte solution containing chemicals for forming said oxide layer on said flat conductive surface of said working electrode to flood said flat conductive surface of said counter electrode surface and occupy the space defined between said flat conductive surface of said working electrode and said flat conductive surface of said counter electrode such that at least said flat conductive surface of said counter electrode is in contact with said organic electrolyte solution and substantially only the flat conductive surface of the working electrode is in contact with the organic electrolyte solution; and causing an electric current to flow between substantially only the flat conductive surface of said counter electrode and substantially only the flat conductive surface of the working electrode, in the organic electrolyte solution, for a period of time and at a magnitude sufficient to cause said chemicals to form said oxide layer on said flat conductive surface of said working electrode.
