Experimental and Numerical Investigation of Electrochemical Transport Phenomenon During Periodic Fluid Flow

摘要将研究两种特定阴极几何形状在层流、切向、周期流存在下电沉积的时空变化。电流分布要确定在一个凹进式绝缘腔底部的阴极和一组三个紧密间隔的阴极。铜与微量银共沉积的实验测量结果将与带有输运方程的数值模拟结果进行比较。改进的电沉积在从电镀到微电子的广泛行业中具有更高质量产品的潜力。

West ABSTRACT Spatial and temporal variation of electrodeposition for two specific cathode geometries in the presence of laminar, tangential, periodic flow will be investigated. Current distributions are to be determined for a cathode at the base of a recessed insulating cavity and for a set of three closely spaced cathodes. Experimental measurements of the codeposition of copper with trace amounts of silver will be compared to results from numerical simulations with the transport equations. Improved electrodeposition has the potential for higher quality products in a broad range of industries from plating to microelectronics.
