Corrosion resistance of titanium in acetic acid
Thread Content
Corrosion resistance of titanium in acetic acid: Titanium exhibits excellent corrosion resistance in acetic acid solutions, regardless of the concentration. Even at temperatures ranging from 200 to 230°C, as long as the solution is in contact with air or contains substances that promote its passivation, it remains a very good corrosion-resistant material, even in the presence of reducing impurities such as formic acid, Cl‑, Br‑, etc. The excellent corrosion resistance of titanium in acetic acid is primarily determined by the passivation film formed by oxidants. In addition to oxygen, water also acts as an oxidant; heavy metal ions, nitric acid, chromic acid, nitrogen, and others are all passivating agents. Therefore, titanium can be used in peracetic acid (acetic acid), ethyl acetate, and acetic acid media.
Titanium acetate materials indicate no pressure, with an annual corrosion rate of less than 0.05 mm
They are all experts; we don’t dare express different opinions – we can only learn silently.
For sulfuric acid, the corrosive effect of concentrated sulfuric acid is significant, right?
Well, high temperatures in sulfuric or hydrochloric acid (eighty or ninety degrees) are not acceptable, as corrosion occurs very rapidly
I’m really curious to know which media are not suitable, so as to make fewer mistakes. Criticism is remembered better than praise, you know
Sulfuric acid, hydrochloric acid – it doesn’t work when the temperature is high.
