Effect of PTFE Content on Microstructure and Tribological Properties of Cu-Sn Coating

Abstract:

The aim of this paper is to obtain the Cu-Sn-PTFE composite coating with wear-resistant and antifriction properties, which can improve the comprehensive performance of Cu-Sn coating and satisfy the self-lubricating property in special working condition. This coating was prepared by pulse current on the basis of non-cyanide pyrophosphate-stannate Cu-Sn plating bath. The effect of PTFE content on the microstructure, composition, microhardness, and tribological properties were analyzed and compared in detail. Results show that with appropriate PTFE content, the composite coating of Cu-Sn-PTFE displays preferable low friction and anti-wear behavior.
