| Abstract: |
| Hot acid immersion corrosion experiments were carried out on fluororubber 246 using hydrochloric acid solution with a mass fraction of 0.05 hydrochloric acid at 80 ℃. The thermal performance，tensile properties and surface morphology of the samples before and after immersion were tested. The results showed that，the hot hydrochloric acid immersion had little influence on the thermal performance of the sample，and the tensile properties decreased. The smooth sample surface became rough from smooth after acid immersion，and holes with different size were formed on the sample surface. The addition of barium sulfate could inhibit the corrosion of hot hydrochloric acid. |
