Abstract :
Bilayer and alloyed thin films of Cu-Ni were successfully prepared by RF magnetron sputtering method. XRD analysis showed polycrystalline film with preferred orientation for both bilayer and alloyed thin films. Nanograins were observed by FESEM. The results of electrochemical experiments indicated that the alloyed films exhibited superior corrosion resistance followed by bilayer and bare 316L stainless steel in 3.5% NaCl solution.
