Tribological Properties of Pb-Sn-CNTs Composite Coatings
Multi-walled carbon nanotube (MWCNT)/Pb-Sn composite coatings were prepared by electrodeposition technique. Friction coefficient and wear weight losses were investigated on a double rings apparatus using carbon steel (C: 0.45%) rings as counterparts under wet friction condition. Tribological characteristics were compared among the samples as carbon nanotubes concentration was changed in the bath. The results indicate that the composite coatings had smaller friction coefficient and weight loss than that of ordinary Pb-Sn coatings under the same work conditions. In addition, the wear performance of Pb-Sn-CNTs composite coating was optimized when the CNTs concentration in bath was 2 g L-1.
