    Abstract: Effective fillability and the uniformity electrodeposition of a copper electroplating solution is judged by determining the time-dependent potential change thereof at a cathode current density of 0.1-20 A/dm2. The potential change is determined at a working electrode rotation of 100-7500 rpm, and the fillability with the solution is judged from the curve profile. In an embodiment of the present invention, the fillability is judged by obtaining the potential change speed in the initial stage of electrolysis and the potential convergent point from the time-dependent potential change curve for a predetermined period of time after the start of the electrolysis.

  • Publication number: 20130075263
    Abstract: A method of repairing damaged airfoils. The method comprises the steps of stripping thermal barrier coatings from the airfoil. After the coatings are removed, cracks are removed from the airfoil. Cracks that appear in the bond coat area over the airfoil fillet portion are removed by locally grit blasting the fillet portion of the airfoil. This operation also results in locally removing the bond coating from the fillet portion. Cracks and other damage sustained by the airfoil tip are removed and replaced by welding superalloy material. The airfoil then may be cleaned by thermal etching. The airfoil is then placed in a plating tool permitting preferential plating of airfoil areas from which plating has been removed. After plating, the airfoil is then heat treated to diffuse the platinum coating with the superalloy substrate materials. The diffusion heat treated airfoil is aluminided by any aluminiding process, forming a PtAl coating.

  • Patent number: 8372258
    Abstract: The working electrode in the flow channel of a flow-through electrolytic detection cell is preconditioned by flowing a preconditioning electroplating solution with preconditioner species through the flow channel while applying a negative potential. Flow of liquid through the flow channel is rapidly switched from preconditioning solution to a target solution containing an organic target solute to be measured. The transient response of the system resulting from exposure of the working electrode to organic target solute is detected by measuring current density during an initial transient time period. An unknown concentration of target solute is determined by comparing the transient response with one or more transient responses characteristic of known concentrations. A preferred measuring system is operable to switch flow from preconditioning solution to target solution in about 200 milliseconds or less.

  • Publication number: 20120273361
    Abstract: The present invention relates to novel metallic composites that are useful as coinage materials. These composites are produced through a multi-ply plating process and are designed to overcome difficulties associated with calibrating vending machines that can result in fraud. In one embodiment, the metallic composite comprises a steel core over which nickel and then a non-magnetic metal such as copper, brass or bronze is deposited as a layered pair. The magnetic and non-magnetic metals may also be applied in the reverse order, with the copper, brass or bronze applied directly over the steel and then covered by the nickel. The electromagnetic signature (EMS) of the composite is controlled by defining the thickness of the deposited metal layers. Advantageously, the invention overcomes problems associated when different coins are made from the same alloy and have similar sizes, and therefore cannot be distinguished by vending machines.

  • Patent number: 8147670
    Abstract: The present disclosure generally addresses the problem of controlling a plating profile in multi-step recipes and addresses, in particular, the problem of compensating for variations of the plating tool state to stabilize the plating results. The compensation is done by adjustments of corrections factors for currents of a plating tool in a multi-anode configuration. The described method enables control of recipes with different current ratios in each recipe step and models different deposition sensitivities in each recipe step. Generally, the method of the present disclosure requires a measurement step, where the tool state is determined, and a data processing step, where the correction factors are set based on models describing the plating process and the tool state.
