An apparatus for measuring the adherence of zinc electrodeposited from acid zinc sulfate solutions on aluminum cathodes is described. Adherence was recognized as "sheet" or "spot" behavior. Chloride favored increase in sheet adherence and fluoride ion favored spot adherence. Mechanical, thermal, and electrolytic treatments of cathode surface as well as chemical composition of electrolyte were investigated. There was no correlation between surface roughness and adherence. Smaller aluminum crystals in the cathode surface favored stronger adherence.
