Re: Hard Anodizing
Just for my own curiosity, why do you need the hard anodize? Type II anodize grown to the thicker levels is difficult to tell from Type III.
It is preferred and will eliminate many problems if you have a PS that is CC capable.
I've read some on the oxalic acid anodizing but don't know enough to recommend anything on it. Something to consider. Was anything said about the size of tank using that method? The agitation will have to be super aggressive and even with the agitation at an optimum level, the tank size will have to be on the large size to dissipate the heat generated from running that much current through the circuit. From experience with a 20 gallon tank, pushing 7 to 10 amps through the circuit was causing heat problems even with aggressive agitation and cold ambient cooling. One pipe with 73.341" SA will have a set amperage of 7.64A for 15 amps per square foot and a set amperage of 10.19A for 20 amps per square foot. That's only one pipe. I'm not trying to dissuade you on anything but maybe bring to light something not considered.
