Electrodeposition and Tribological Properties of Self-Lubricating Sn-Ni-PTFE Composite Coating

Abstract:

In order to improve the self-lubricating and anti-wear performances of metal surfaces in the extreme conditions, Sn-Ni-PTFE composite coating was electrodeposited on metal surfaces from the electrolyte containing PTFE emulsion. Microstructure, microhardness and tribological properties of the Sn-NiPTFE composite coatings were investigated. Results show that Sn-Ni-PTFE composite coating has smooth surface and fine microstructure. PTFE particles disperse uniformly in the composite coatings. Simultaneously, the incorporation of PTFE particles significantly improves the tribological performance of Sn-Ni coatings. SnNiPTFE composite coatings exhibits lower friction coefficient and better wear resistance in contrast with Sn-Ni coating.
