Abstract: A system for electro-coating a metallic substrate includes a DC power supply, a primary electrode, and a wireless auxiliary electrode. The primary electrode transmits electrical current through electrolyte fluid when energized by the power supply. The auxiliary electrode is within the drain hole, and receives the current from the fluid at one end. The auxiliary electrode boosts the calibrated voltage at the opposite end near the drain hole. In a method for depositing thin film material onto the internal surfaces, the wireless auxiliary electrode is positioned in the drain hole, and the calibrated voltage is applied from the DC power supply to the primary electrode. Electrical current transmitted through the fluid is received at the first end of the auxiliary electrode. The calibrated voltage is boosted in proximity to the drain hole at the second end of the same auxiliary electrode. A wireless auxiliary electrode assembly is also provided.

Abstract: A method for the electrophoretic coating of workpieces with a coating medium, in particular lacquer, and a coating installation are described. In the method, at least one workpiece is immersed in the coating medium. With a voltage source, a d.c. voltage is applied between the workpiece and at least one electrode immersed in the coating medium. The d.c. voltage is increased continuously, in an essentially stepless manner, throughout virtually the entire coating operation in such a way that the coating current density on the surface of the workpiece remains essentially constant over time.

Abstract: An apparatus and method for mineralising demineralised and hypo-mineralised biological material such as tooth or bone. The apparatus has a probe electrode for receiving a mineralisation agent and a counter electrode. It is also provided with a controller to control the electrical signal provided to the probe such that the extent of mineralisation of the biological material is controlled by modulating or changing the electrical signal provided by the probe based upon the measured output of the circuit formed from the probe, counter electrode and biological material. The electrical output provides a measure of the extent of mineralisation of the biological material which is compared with data from a reference technique which gives 3D structural information on an area of interest in the biological material.

Abstract: Embodiments described herein generally relate to methods and apparatus for forming an electrode structure used in an energy storage device. More particularly, embodiments described herein relate to methods and apparatus for characterizing nanomaterials used in forming high capacity electrode structures for energy storage devices. In one embodiment a process for forming an electrode structure for an energy storage device is provided. The process comprises depositing a columnar metal structure over a substrate at a first current density by a diffusion limited deposition process, measuring a capacitance of the columnar metal structure to determine a surface area of the columnar metal structure, and depositing three dimensional porous metal structures over the columnar metal structure at a second current density greater than the first current density.

Abstract: An electro-composite tribological coating for coating a flexible or compliant structure, for example a structural seal, includes a cobalt and cobalt alloy base containing a fine dispersion of tribologically suitable particles such as chromium carbide (Cr3C2), silicon carbide (SiC), carbon graphite, and the like, which can be deposited directly on the outer surface of the seal as a near-net shape coating requiring little or no mechanical polishing or grinding. The coating is deposited on the seal in one embodiment by an electrolytic bath. In this manner, a near-net shape coating of a desirable thickness, for example having a thickness of about 0.005? and a desirable surface finish can be achieved in the as-plated condition with little or no additional polishing or grinding after coating.

Abstract: A method for forming a patterned metallic layer on a substrate is employed to form a first layer on top surface of the substrate. A patterned mask layer is then deposited on top of the first layer, thereby exposing selected portions of the first layer. Thereafter, a second and a third layers are successively formed on top of the selected portions of the first layer, and the patterned mask layer is removed. Subsequently, the first layer is removed except the portions thereof intervening between the top surface of the substrate and the second layer by using a dry etching method to thereby form the patterned metallic layer including the second layer and the exposed portions of the first layer.

Abstract: An overload protection and control circuit and methods for electrocoat painting systems is disclosed. A resistive shunt is utilized to generate a voltage proportional to the level of current flow to electrodes in the electrocoat painting system. After amplification, the generated voltage is compared with a reference voltage. If the current exceeds a predetermined level, indicative of an overcurrent condition, a comparator causes a control circuit to disable current flow. A timer is provided to delay re-enabling of current flow for a predetermined delay interval. The control circuit may receive inputs from a control PLC or computer. The control PLC or computer may receive inputs from sensors such as a pH sensor or a membrane monitor. The control PLC or computer may selectively control the control circuit to various electrodes so as to more appropriately operate the electrocoat painting system.
