This set shows the results of using LCD electrolyte at current densities well beyond the specified LCD range. Electrolyte temperature was held to 70 -72 deg. F. in this set. The excellent results are not what I was expecting, none the less the fact remains. Neilfj took most of this data, I thank him again for his assistance.

As in the previous set of curves, lower ASF shows higher bulk resistance.

Judging by the slope of the curves, the dissolution rate is much less than 9.4% electrolyte. At current densities of 5 ASF or higher the curves practically flat line. You can see now why 6 ASF is my favorite LCD current density.

The real surprise was no evidence at all of pores that were too small, in any of the ASFs tested. They all dyed easily and perfectly. The coating thickness were 10 to 15% thicker than those grown under the same conditions with 9.4% electrolyte. This has potential.

LCD electrolyte may be the way to go with "difficult" alloys like 2xxx and 7xxx. The dissolution effects are much less. The only down side is that you will need to have a little more voltage available. If you aren't using a battery charger, more voltage is a non-issue.
