Title

Optimizing Additive Ratios in Alkaline Zincate Electrodeposition

Abstract

Alkaline non-cyanide zinc electrogalvanizing is utilized in some plating applications. This study was conducted to evaluate the effects of a commercial carrier, booster, and leveler in a strong zinc (37.5 g/L) and alkaline (210 g/L) plating solution. Hull cell plating was used to assess the roles of each additive on the appearance of the zinc deposits produced from synthetic solutions. Bright white deposits were generated with several different combinations of additives at current densities of 170-420 A/m2. The zinc structures were characterized using x-ray diffraction and scanning electron microscopy to understand the microstructure which produced the bright deposits in order to determine the optimal conditions leading to mirror-like deposits.
