I'm about to try to anodize some 6061 parts that I've buffed
with Tripoli.
They are obviously 'waxed' from the buffing compound. There is
no visible residue, but water beads on them like a freshly waxed car.
Should I go straight into degreaser, or scrub them down in acetone or
lacquer thinner first?
Also I strongly suspect SP degreaser is TSP. I considered trying acetone
followed by TSP, but if TSP is the same as SP degreaser there wouldn't
be much point.
Also the LCD manual shows the caustic etch step with anodize stripper
in one spot, but not in others. The same for acid neutralization with
baking soda before dye. Should I do these steps?
I've got an RO-DI filter system with a 50gal tank and a pump fed garden
hose nozzle. I can probably do a really good rinse between steps so I was
considering skipping the acid neutralization.
I'm worried the caustic etch will kill my buffed surface completely, but if it
improves the process I can lose a little shine.
I've also noticed the manual calls for both 4.5A/ft2 and 3.0A/ft2 in
different places. Which would you reccomend for a first try at LCD?
I've got a PC interfaced voltmeter with graph output. Whatever the current
I will go till I can see PAR has occured.
Is there any difference at all between GP plates and Al sheet for the cathode?
I'm doing a fairly large total surface area and wondered if I would be better
off nearly lining the bucket wall with sheet Al.
Thanks
