Plating Tank Agitation

Zinc plating

Some visuals of the plating tank in action.

Tank is a clear plastic file-folder container, holds about 3.5 gallons total (I use it at 3 gals). Wal-Mart for $5.50

Agitation is by Rio 600 aquarium pumps. These are fully submersible, using a magnetic impeller system, so there is NO exposed metal of any kind. Rated at 200 GPH free flow. Relatively cheap too(I paid either $9.95 or $14.95 each, can't remember now). I have used them in both the zinc electrolyte and anodizing acid. So far they're still working fine.

Videos are MPEG-4 in Quicktime movie wrappers.

A part in the zinc electrolyte, ready to start plating.

This part is 48 sq-in, plated at 4.5 Amps, for a current density of @ 94 mA/sq-in. The more area you plate, the more vigorous the fizzing becomes.

Videos show the fizzing after power is applied

The same part, videos show how the agitation clears the fizzing away, and carries it off.

The entire tank. Liquid agitation is evident. This tank could probably use 2 pumps
