基于FDM的PTFE/PEEK多孔轴承保持架材料制备与摩擦学性能研究
Preparation and Tribological Properties of PTFE/PEEK Porous Bearing Cage Materials Based on FDM
摘要
Abstract
Polytetrafluoroethylene/polyetheretherketone(PTFE/PEEK)binary composite porous materials were prepared by fused deposition molding(FDM)process,and the mapping mechanism between microstructure and macroscopic tribological properties of the materials was researched.The results showed that the PTFE/PEEK porous materials prepared based on FDM process had a positive pore-forming effect and the pores of the porous samples were more dense with the increase of NaCl mass fraction,and the oil content of PTFE/PEEK porous materials was directly proportional to the change of the porosity,and the oil retention rate of the materials was the highest when the mass fraction of NaCl was 53%,and the oil retention rate of all the samples was higher than 90%.Under dry friction conditions,the addition of PTFE improved the tribological properties of the materials to a certain extent.Under the oil-poor lubrication condition,the friction coefficient was lowest for the 6#sample with a NaCl content of 63%,and the combination of the oil supply and oil-containing capacity of the porous structure and the lubricating property of PTFE could give the composites good tribological properties.This study provides a reference for the molding and application of PEEK-based porous bearing cage materials.关键词
