How does chromium prevent corrosion

WebElectroplating improves the corrosion. resistance of metal objects. Sacrificial protection Iron can be protected from rusting if it is in contact with a more reactive metal, such as zinc. WebThese carbides are chromium-rich, and therefore reduce the chromium concentration in the austenite adjacent to the grain boundaries, thus creating the conditions for intergranular corrosion, as shown in Figures 19.10 and 19.11. Chromium carbides are formed more rapidly in steels with higher carbon concentrations, as can be seen in Figure 19.12 ...
