Passivation is a widely-used metal finishing process to prevent corrosion. In stainless steel, the passivation process uses nitric acid or citric acid to remove free iron from the surface. The chemical treatment leads to a protective oxide layer that is less likely to chemically react with air and cause corrosion. • #polytechnic • #applied_chemistry • #uttarakhand • #ncert • #india • #cbse • #engineering_chemistry • other video link • blood group • • Blood group and RH factor • ores of iron • • Ores of iron • purification of metal • • purification of metal • …… ........................................... • • Extraction of metal from its ore • • Extraction of Metal from its ore • ,.................................................. • Estimation of Hardness of water by O' Hehner method • • Estimation of Temporary Hardness by... • ECS- Portrait of a Lady • • Portrait of a Lady|| • Khusbant singh part-1 • • Portrait of a Lady part-2 • • Portrait of a Lady part -2 • • Portrait of a Lady part-3 • • Portrait of a Lady part- 3 • The Doll's house • • The Doll's House • Octane number or quality of fuel • • Octane number|what is octane number||... • ..................................... • direct chemical attack corrosion • • Corrosion संक्षारण in engineering che... • • • AR academy • / @pahad87 • #passivitystainless steel passivation
