Vanadium Plating: Strong Vacuum Deposition Advice

Summary for vanadium plating Discussion

vanadium plating is discussed as a vacuum-deposition problem rather than a conventional electroplating one. Vladimir Shvarts asked whether vanadium could be plated for a superconducting shield, noting that niobium would be better but seemed nearly impossible to plate, and that lead was his fallback despite oxidation and softness. In an editor’s note, readers were pointed to separate niobium-plating threads for more on that metal. The only answer, from an unnamed contributor, said vanadium and niobium should be depositable by vacuum methods without much trouble. The suggested routes were sputtering, e-beam evaporation, and cathodic arc deposition, with the responder guessing that vanadium may be somewhat easier than niobium. No wet-plating process was offered, and the practical takeaway is that vacuum deposition is the recommended path for either metal.

Q. I want to make a superconducting shield for low-T application. Is there any technique to plate with Vanadium? Nb is better, but as far as I see it is almost impossible to plate with. And my last choice is lead. It is good as superconductor, but oxidizes and very soft. So, any clue where to look on vanadium plating? I would really appreciate any advice.

Thank you,

A. You should be able to vacuum deposit niobium or vanadium without much trouble. You can sputter, e-beam evaporate, or cathodic arc both metals, though I would guess that vanadium is somewhat easier than niobium.

A. I have successfully plated Vanadium using Vanadyl sulphate at about .1M and you can use Boric acid as the buffer or Na acetate. The plating works best at a pH of 5-5.6. You might have to play around with it in a Hull Cell ⇦ huh?
to find the right amps per square foot, you can also add Na sulphate to increase the conductivity. I use about 11 g/L. This bath gives a very shiny finish.
