Statistical investigation of the layer tlxickness distribution from an alkaline zinc - iron electrolyte -

In the following, a statistical investigation of the deposits of zinc-iron alloys from an alkaline electrolyte is undertaken. By m e a n s of a systematic variation of the zinc, hydroxide, and iron concentrations these factors are investigated a s to their effect on zinc-iron barrel plating of screws. In the investigation, the various factors affecting the: Barrel-current yield, layer thickness on the head and on the middle of the screws as well as the distribution of the layer thickness from object to object, are clarified. Furthermore the effect of various dectmlyte compositions on stress in the deposits will be presented at the conference.
