چکیده
|
Corrosion behavior of nano-coblat-coated ni sheet was compared with pure ni and 20% fe-ni alloy sheet using potentiodynamic polarization and linear polarization technique in 0.1 m nacl solution at room temperature. results showed that corrosion resistance properties of nano-co-coated ni sheet were almost same as that of pure ni sheet,however corrosion resistance of 20% fe-ni sheet was decreased significantly. pitting potential of 20% fe-ni sheet was subsequently decreased as compared to pure ni sheet as well as nano-cobalt-coated ni sheet. sem/eds analysis of the corroded surfaces showed that both pure ni and nano-coblat-coated ni sheet did not show any appreciable corrosion however significant corrosion was observed in the case of 20% fe-ni sheet. © 2013 nasser al-aqeeli and ihsan-ul-haq toor.
