A multi-nanolayer of Ni/Cu with the total thicknesses of 3 μm was successfully produced on Cu substrate via electrodeposition process through dual bath technique (DBT). The electrodeposition with 3 different sublayer thicknesses (40 nm, 80 nm and 100 nm) was produced by varying the deposition time. The results of electrochemical experiment indicate that Ni/Cu multi-nanolayer coating have superior corrosion resistance in 3.5 wt % of NaCl solution than the uncoated Cu substrate. The corrosion resistance is increased when the sublayer thicknesses decrease. The morphological analysis of Ni/Cumulti-nanolayer after corrosion testing was examined. The results shows that the uncoated Cu substrate corrode faster if compared to that of Cu substrate coated with Ni/Cu multinanolayer coating. 2016-03-22T03:57:01Z 2016-03-22T03:57:01Z 2015 Article Applied Mathematics and Computational Intelligence (AMCI), vol.4 (1), 2015, pages 355-360 2289-1323 (online) 2289-1315 (print) http://amci.unimap.edu.my http://dspace.unimap.edu.my:80/xmlui/handle/123456789/41181 en Institute of Engineering Mathematics, Universiti Malaysia Perlis |
