Abstract: Bipolar current electrodeposits a nanocrystalline grain size. Polarity Ratio relates the absolute value of time integrated amplitude of negative polarity and positive polarity current. Grain size can be controlled in alloys of two or more components, one of which being a metal, and one of which being most electro-active. Typically the more electro-active material is preferentially lessened in the deposit during negative current. The deposit is relatively crack and void free. Grain size is typically a function of deposit composition, which is typically a function of Polarity Ratio. Specified grain size can be achieved by selecting a corresponding Polarity Ratio. Coatings can be in layers, each having a grain size, which can vary layer to layer and also in a graded fashion. A finished article may be built upon a substrate of electro-conductive plastic, or metal, including steels, aluminum, brass. The substrate may remain, or be removed.

Abstract: A process for cathodically reducing unwanted Fe+3 ions to needed Fe+2 ions in an acidic ferrous based plating bath without reducing agents is disclosed. An auxiliary potential of 0.1 to 0.3 volts vs. SCE is applied between the working electrode and a reference electrode and can reduce the molar ratio [Fe+3]/[Fe+2] to 1 ppm without depositing Fe or other metals on the working electrode or causing hydrogen evolution. The process is applicable to electroplating soft magnetic films such as NiFe, FeCo, and CoNiFe and can be performed during plating or during cell idling. The process is cost effective by reducing the amount of hazardous waste and tool down time due to routine solution swap. Other benefits are improved uniformity in composition and thickness of plated films because issues associated with decomposed reducing agents are avoided.
