Abstract
New developments and emergence of nanotechnologies have stimulated efforts to develop high performance coatings. In the present study, the influence of laser surface modification on the corrosion characteristics of an electrodeposited nanostructured Ni-Co thin coating is examined. Electrodeposited coatings were peeled-off from the substrate surface and subjected to laser surface irradiation using three different laser power levels; 90 W, 110 W, and 140 W. It was observed that the irradiated sample at 140 W was bent towards the irradiation direction. The surface of this sample experienced cracking upon observation using SEM and following electrochemical test. The effect of laser irradiation on the overall corrosion performance of the electrodeposited Ni-Co coatings was assessed. It was found that laser irradiation had no noticeable effect on the corrosion potential. Nevertheless, there was a systematic shift of the pitting potential towards more active values as the laser power intensit
