Just make extra sure not to use stainless electrodes. Nasty stuff generated.

Got to admit that this thread may be long but a very good tip indeed.

It has saved me hours on derusting and cleaning with the usual brushes and other items and made the process a bit cleaner

Excellent thread and tip

I've just cleaned two cast iron brake discs using this method. Absolutely brilliant and no damage to machined faces. Flywheel won't be a problem (assuming it isn't dual-mass etc).

I personally wouldn't want to electrolysis a production flywheel. It's such a critical and highly stressed part, so the possibility of hydrogen embrittlement weakening an already relatively brittle cast part would rule out electrolysis for me. You say it's not much rust, and it's not a complex shape, so 10 minutes with the wire brush would probably be a better idea.

Electrolysis - Tried it at last

Finally decided I'd better get on and refurb the front uprights and callipers.

Not sure why 'd put it off before but finally decided to give electrolysis a go.

The electrodes were just off cuts from the chassis which I wired to a piece of copper tube resting on a bucket. The solution was washing soda at a concentration of approx 1 tablespoon / 5 litres of water.

Battery charger didn't show much current but overnight the process worked very well although I did have to wire brush it fairly thoroughly afterwards.

Anyway, if youre thinking about electrolysis then give it a go. just wish I knew about the process when I was restoring my Austin 7!

Hydrogen embrittlement

When plating components we have had some problems with hydrogen embrittlement. The "de-embrittlement " process is 250°C for 90mins. Having siad that it's only going to be a problem for highly stressed items. for example caliper bolts, road springs etc. The de-embrittlement should be done straight after the electrolysis.

Electrolysis Vs. Molasses

I have done both, and I`ll go for the molasses method.
I don`t think it has any of the problems associated with electrolysis.
Maybe a little bit slower.

For goodness sake!

That links suggests using a stainless steel electrode.... which as has been discussed in this LB thread gives off a very nasty poisonous gas!

Be warned!

The poison is in the liquid, Chromium salts dissolved.

Hydrogen Embrittlement

While this is a awesome thread and the process seems to be almost magical I have one worry.

I have tried to make sense of Hydrogen Embrittlement and also this de-brittlement process.

Is there anyone out there who understands and has researched this part of this process. I would hate to be doing 80mph and hit a bump and a suspension arm snaps only to be told 'cause of accident - hydrogen embrittlement' ' no insurance payout' and also I am dead.

Is this a worry or should I just slap myself with a fish and get out my battery charger????

Irony, as your name suggests you may be worried.

Have a read of THIS, it may put your mind at rest and let you get on with it
