| 20090130479 | Articles incorporating alloy deposits having conrolled, varying, nanostructure - Bipolar wave current, is used to electrodeposit a nanocrystalline grain size. Polarity Ratio is the ratio of absolute value of time integrated amplitude of negative and positive polarity current. Grain size can be controlled in alloys of two or more components, at least one of which is a metal, and at least one of which is most electro-active. Typically, the more electro-active material is preferentially lessened during negative current. Current density, duration of pulse portions, and bath composition are determined with reference to relations showing grain size as a function of deposit composition, and deposit composition as a function of Polarity Ratio, or a single relation showing grain size as a function of Polarity ratio. A specified size can be achieved by selecting a corresponding Polarity Ratio. Coatings can be layered, each having an average grain size, which can vary layer to layer and also graded through a region. | 05-21-2009 |

| 20090057159 | Method for producing alloy deposits and controlling the nanostructure thereof using negative current pulsing electro-deposition - 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. | 03-05-2009 |
