Abstract

A method of numerical calculation is developed for predicting twodimensional shape changes at a cathode during electrodeposition. The calculation uses finite element methods to obtain the secondary potential field distribution in an electrolysis cell. The cathode shape initially consists of parallel metal strips which are separated by, and coplanar with, insulating strips; the anode is at a fixed distance from the cathode. Transient numerical calculations provide a complete time history of cathode shape during deposition. Results are obtained in order to compile dimensionless shape change dependence on coulombs passed, polarization parameter, applied potential, and initial cathode shape.
