Development of MoS2 Nanosheets Embedded Nickel Composite Coating and its Mechanical Properties

Abstract

MoS2 nanosheets were prepared by a facile hydrothermal method and its morphology and structural properties were characterized by FE-SEM and XRD analysis. MoS2 nanosheets reinforced Ni composite coatings were prepared by a simple electrodeposition method using various concentrations of MoS2 in Watts nickel plating bath. Surface morphology, microstructure and crystal orientation of pure Ni and Ni-MoS2 composite coatings were characterized by FE-SEM and XRD analysis. Microhardness and wear resistance of pure Ni coating were improved by the addition of MoS2 nanosheets in the Ni matrix to use as solid lubricant.
