Abstract: An object of the present invention is to provide a method and system of electroplating using an anode that can be prepared relatively easily without the need for ancillary equipment or anolyte management, and without the need for expensive metals or special metals. The present invention relates to a method of electroplating an article with metal, the method comprising the steps of: allowing a current to flow in a plating bath containing ions of the metal and an organic compound additive, wherein the plating bath comprises the article as a cathode and a conductive base material as an anode, a part of a surface of the conductive base material is covered with an insulating material, and a remaining part is exposed, and a current flowing portion is dispersedly present in the anode.

Abstract: Corrosion of metal surfaces, particularly aluminum or aluminum alloy surfaces, is inhibited by contacting the metal surfaces with a solution comprising a mercapto-substituted silane and then preferably baking the metal to cure the silane coating. Multifunctional organo-mercapto-substituted silanes are preferred in the practice of the process. Preferably, the treatment solution is an aqueous mixture of the mercapto-substituted silane and selected solvents.
