thunderhorse Posted October 10, 2009 Share Posted October 10, 2009 Don't know if this would have been better in arts and crafts, but...I'm experimenting with electrolysis to de-rust metals and vehicle parts. The anode should be mild steel/iron ideally (or stainless at a push). I don't have plate lying around, but I do have quantities of rail/montant offcuts from plasterboarding.Does anyone know what the bright coating is on these sections? It's not galvanised (not as I remember galvo.,) so could it be very thin stainless?Suggestions welcome.Cheers [:)] Link to comment Share on other sites More sharing options...
dave21478 Posted October 10, 2009 Share Posted October 10, 2009 DO NOT use stainless anodes. These produce a chemical byproduct which I cant remember offhand ...somethingsomthinghexachromate or similar. It is very, very poisonous. Link to comment Share on other sites More sharing options...
Chancer Posted October 10, 2009 Share Posted October 10, 2009 They are electro-zinc plated and not passivated. Link to comment Share on other sites More sharing options...

Either way, I would only use it - as I said - at a push. The jury is still out on that one. Link to comment Share on other sites More sharing options...
thunderhorse Posted October 10, 2009 Author Share Posted October 10, 2009 [quote user="Chancer"]They are electro-zinc plated and not passivated.[/quote]So that would mean grinding it off to get back to the original bare metal...Think I'll go to a scrappy and get some plate/bar.Thanks for the input, peeps.Cheers [:D] Link to comment Share on other sites More sharing options...
