Hello All,
I decided to watch a YouTube clip
Old Soviet motorcycle full Restoration, accessed 17th January 2021 from
https://www.youtube.com/watch?v=y8HEZ-x4-_w .
The clip showed an electrical treatment that did not involve the usual tanks and immersion I associate with electrolysis rust treatment. Can someone confirm what the type of treatment actually is for me?
The treatment appears as follows - with timestamp in brackets [ ] ...
[6:00] taking alloy sheet out of AA battery cutting the alloy into small squares. Partially filling a glass jar with Orthophosphoric acid (Phosphoric) [6:24] and putting the alloy squares into the acid. Getting another AA and placing some cloth over the negative end of the AA battery.
Getting a 12 volt car battery and hooking an earth lead up to a steel motor cycle rim [6:52). The second lead is hooked to the positive terminal and the other end of the lead is hooked onto the positive end of the cloth covered AA battery.
The cloth end of the AA battery is dipped into the glass jar [6:57]. The wet cloth end of the AA battery is then rubbed on the steel motor cycle rim which completes the circuit [7:06}.
After treatment the rim is sanded down [7:25]
Is there a specific name for this treatment and what is it used for? How good or functional is this process?
Kind regards
Lionel
