Corrosion mechanism of Ni-Cr alloy in boiling fluorine-containing nitric acid: Effect of chromium content

Key Points

• Corrosion rates significantly increase with higher chromium content in ni-cr alloys.
• In tests, samples exposed to boiling fluorine-containing nitric acid showed marked degradation.
• Observation of corrosion mechanisms was done through detailed chemical analysis and surface examination.
• Findings may indicate potential for improved resistance in industrial applications using ni-cr alloys.],
