Abstract

In this study, Ni/MWCNT composite electroplating was developed with a dispersed MWCNT Ni plating bath. The MWCNT was dispersed uniformly in the bath by a dispersion material and the Ni/MWCNT composite was electrodeposited from the dispersed MWCNT nickel plating bath. The Ni/MWCNT composite electroplating obtained at the optimum conditions showed flat and smooth surfaces. The Ni/MWCNT composite electroplating obtained in this study showed excellent mechanical and thermal characteristics. This Ni/MWCNT composite plating also demonstrated outstanding wear characteristic as sliding contacts. Especially it had an outstanding thermal characteristic of emissivity, in the broad wavelength range and dissipated the heat generated in the thermal chamber effectively. Maximum emissivity reached 0.89 (wavelength: 3-30μm) . Additionally, it maintained a high fixed value for that wavelength. It had the effect of decreasing heat resistance as a heatsink.
