Improvement in Tribological and Anticorrosion Performances of Co-MoS2 Composite Coatings
The dispersity of incorporated particles is critical for the creation of composite coatings with enhanced performance. Here, we propose a mechanical agitation and ultrasound-assisted pulse electroplating technique for producing exfoliated MoS 2 reinforced cobalt-based composite coatings with improved tribological and electrochemical properties. The dispersity of exfoliated MoS 2 and its corresponding effect on the microstructure, microhardness, tribological and electrochemical behaviors of the resultant composite coatings are systematically investigated. The results reveal that the outstanding dispersity of exfoliated MoS 2 in electrolyte is beneficial to its even distribution and incorporation in the composite coating, endowing the resultant composite coatings with a smooth surface, compact structure, high hardness, remarkable antiwear and friction reduction performance as well as superior corrosion resistance. This study offers a strategy for producing high-performance composite coatings with promising practical applications. Graphical Abstract
