Abstract
Shape change processes were investigated at a cathode consisting of parallel metal strips separated by, and coplanar with, insulating strips. Copper deposition was carried out in well-stirred acidified sulphate baths with controlled variation of conductivity and potential. At various times during the course of deposition, the cathode shape was measured with a stylus-type profilometer. Experimental data were compared with theoretical calculations made with a finite element model which predicted evolution of smooth deposit shapes based on secondary current distribution principles. Agreement between experimental and theoretical results was good, but was adversely influenced by surface roughness which was not accounted for in the calculations.
