초록

Ni-CNT(Carbon Nanotube) composite coatings is were formed by electrodeposition and their physical properties were investigated with variations of CNT content(1, 3, 6. 9 g/L) in the electrolyte solution, while the current density and electroplating time were fixed respectively at $6A/dm^2$ and 90 min.. With increasing CNT content from 1 to 9 g/L, incorporated CNTs into the composite coating were limited from 4.65 wt.% to 7.38 wt.%. Microhardness and contact angle values were increased with increasing CNT content of upto 3 g/L. With increasing the CNT content further, physical properties were degraded due to agglomeration, poor adhesion of CNTs to Ni matrix and thus rough surfaces. Optimum electroplating conditions were found to be the CNT content of 3 g/L, current density of 6 A/dm2 and electroplating time of 90 min.
