Abstract: An electroplating system includes an enclosure with an interior, an anode lead extending through the enclosure and into the interior, and a porous body. The porous body is supported within the interior of the enclosure for coupling an electroplating solution within the interior with a workpiece. A conduit extends through the enclosure and into the interior of the enclosure to provide a flow of nitrogen enriched air to the interior of enclosure for drying and removing oxygen from the electroplating solution.

Abstract: A method for forming a trivalent chromium coating on an aluminum alloy substrate includes adding a chromium-containing solution to a vessel, immersing the aluminum alloy substrate in the chromium-containing solution, immersing a counter electrode in the chromium-containing solution, and applying an electrical potential bias to the aluminum alloy substrate with respect to its equilibrium potential to form a trivalent chromium coating on an outer surface of the aluminum alloy substrate. A method for forming a trivalent chromium coating on a metal substrate includes adding a chromium-containing solution to a vessel, immersing the metal substrate in the chromium-containing solution, immersing a counter electrode in the chromium-containing solution, and modulating an electrical potential difference between the metal substrate and the counter electrode to form a trivalent chromium coating on an outer surface of the metal substrate.

Abstract: A method of coating a metal substrate is disclosed in which the metal substrate is disposed as an anode in an electrolytic circuit with an aqueous alkaline liquid electrolyte. An electrical voltage differential is applied to the metal substrate and a cathode. The treated metal substrate is disposed as a cathode in an electrolytic circuit with an ionic liquid electrolyte and an aluminum salt. An electrical voltage differential is applied to the metal substrate and an anode to form an aluminum layer on the metal substrate.

Abstract: An ammonia sensor that includes an ionic liquid impregnated sensing electrode (anode) and a cathode separated by a membrane. During operation, in the presence of ammonia, the anode and cathode generate current manifesting the electrochemical reaction of ammonia in the sensing electrode. Ionic liquids distributed in the ionomer film in the gas diffusion electrodes ensure the reactivity under wide range of environment conditions while maintaining the ability of the device to quantify ammonia concentration in the environment. The sensor can therefore sustain long time operation without internal humidification due to the non-volatility of the ionic liquids.
Abstract translation: 一种氨传感器，其包括离子液体浸渍的感测电极（阳极）和由膜分离的阴极。 在操作过程中，在氨存在下，阳极和阴极产生电流，表现出感应电极中氨的电化学反应。 分散在气体扩散电极中的离聚物膜中的离子液体确保了在宽范围的环境条件下的反应性，同时保持了装置在环境中定量氨浓度的能力。 因此，由于离子液体的不挥发性，传感器可以维持长时间的操作而没有内部加湿。
