Rust removal from springs by electrolysis

Rust removal from springs by electrolysis

Rust removal from springs by electrolysis

(OP)
Hello,

I'm removing rust from leaf springs by electrolysis.

The spring is the cathode, the anode is stainless steel, the liquid is a 10% solution of sodium hypochlorite. 5 amp current for around 24 hrs seems to remove the rust.

The question is, is there a risk of hydrogen embrittlement to the spring and a subsequent cracking failure?

Regards George  

RE: Rust removal from springs by electrolysis

Yes there is a risk! By making the spring the cathode you are charging it full of hydrogen. Stick to a mechanical rust removal process like grit blasting.

Thank you for the reply swall. smile

Seems I just was lucky the past thirty years. I will now refrain from the process (and recommending it).

Thank you so much.

best regards George

Well, JK, that beats the crap 'outa 'media blasting'!
