H2S affect on Samarium Cobalt & Coating
H2S affect on Samarium Cobalt & Coating
(OP)
I am trying to research whether a FBE (Fusion Bonded Epoxy) coating would help prevent corrosion of samarium cobalt in deep bore conditions with H2S (Hydrogen Sulfide) - assuming concentration of between 5% - 30%.
Any info gratefully received.

Is this a dry (gas only) application or is there water and oil present also? This will not be a garden variety of epoxy.
I would rather go with a solvent-less liquid system since there will be less chance for porosity.
You could look at FBE in two coats. Holidays are what will kill you.

Those will give you the best chemically inert seal.
