Galvanic corrosion occurs when dissimilar metals contact in electrolyte; more active metal (anode) corrodes preferentially.
चरण-दर-चरण मार्गदर्शिका
- 1Input two metals and galvanic series position
- 2Calculate galvanic potential
- 3Determine which metal corrodes and rate
हल किए गए उदाहरण
इनपुट
Zinc (anode) + steel (cathode) in seawater
परिणाम
Zinc sacrificially corrodes, protecting steel (intentional use)
सामान्य गलतियां जिनसे बचना है
- ✕Assuming only one metal corrodes (wrong)
- ✕Not understanding sacrificial anode concept
अक्सर पूछे जाने वाले प्रश्न
How do you prevent galvanic corrosion?
Use same metal, isolate with non-conductive gasket, or apply protective coating.
