Titanium corrosion prevention issues

Can titanium withstand 200 ppm fluoride ions? Temperature 95-100
After 30 pm, it begins to damage the oxide film on its surface.
200 ppm fluoride ions, temperature 95-100 degrees – is it a gas-phase or liquid-phase material? What are the other components in the material? Is it a pipe? Container? Reactor? Heat exchanger? Only by making things clear can everyone help you more effectively.
No, it’s titanium that is not resistant to fluoride ion corrosion; it gets corroded very quickly, especially in heat exchangers
There have been such cases in evaporators,
Try the hydrofluoric acid-resistant anti-corrosion coating； The lower the fluoride concentration, the easier it is to cause corrosion ； The vast majority of substrates used in industry are susceptible to corrosion by fluorine, which makes things difficult
Graphite heat exchangers can be used for heating, cooling, and absorption in media containing fluoride ions; they enable operation over a long period at the boiling point of 48% hydrofluoric acid.
