Hello everyone in this community! I would like to know if there exists a titration procedure to determine the amount of the acids - sulphuric acid & phosphoric acid and nickel sulphate in the electropolishing solution. I used to carry out the titration to determine just the acids in the past...

The final electropolishing quality is diminishing since the electropolishing bath has started to age. What parameters could be counter-balanced (like potential, current, duration etc) to overcome this so that the same aged solution could be used for further electropolishing?

Thanks, Everyone, I could understand that as the bath is operated, there is an increase in the metal concentration, specific gravity and the electrical resistance of the electrolyte. Moreover, the acidity of the electrolyte decreases and oxidizers or additives are consumed. In addition, the...

Hello all, What are the main factors responsible for the diminishing quality of the final finish when the electropolishing bath begins to sludge? Thanks.

@IRstuff: Thanks for the information.

Hello Arun, Thanks for the message. I do have a few mentors at my workplace. And I gather inputs from these kinds of open forums as well as I am a beginner in Electropolishing. So coming to my question, I did perform a set of experiments with the same solution (Sulphuric acid, phosphoric acid...

Thanks for the answers. I was performing a set of experiments with the same solution (Sulphuric acid, phosphoric acid, water) today. And, every time I measured the Conductivity value after each test, I could see that there was an increase. I couldn't understand why this happened when I was...

Hello Everyone, Would someone here help me with this question: What happens to the Viscosity of the electrolyte when the electropolishing solution ages? Will it increase or decrease? I am considering a mixture of Sulphuric acid, Phosphoric acid and water. Thanks.

Hello Everyone, Would someone here help me with this question: What happens to the Electrical Conductivity of the electrolyte when the electropolishing solution ages? Will it increase or decrease? I am considering a mixture of Sulphuric acid, Phosphoric acid and water. Thanks.

Thank you so much for the reply, it really helped. Regards.

Hello Everyone, Would someone here please let me know what gets dissolved in the electrolyte solution during Electropolishing of Stainless Steel Grade 316? Thanks.

Hello, Thanks, that's OK, no problem. I understand. Regards.

Hello, Thanks for the reply. Would it be possible to share the name of the chemical supplier? Would you please share me the range of current density or voltage drop that you work? Thanks, BV Krish

Hello, Thanks for your reply. I am performing a study on how the electrolyte ageing affects the quality of electropolishing. I was wondering if the industry has a standard value for the amount of charge that has to be maintained for a unit volume of electrolyte for perfect electropolishing...

I was gathering some information on the ageing of electrolyte bath used for EP in industry. Would someone please let me know if there is a standard value for the amount of charge that has to be maintained per unit volume to in order to achieve a quality controlled approach for EP?
