- Abstract
The polyetheretherketone (PEEK)-based self-lubricating bearing cage materials are prepared by fused deposition modeling( FDM)process, and the synergistic design of preparation, microstructure and macroscopic properties of the materials are studied. The results show that: the pore size of porous PEEK samples prepared by FDM process meets the requirements of porous cage materials; the oil content of porous samples is affected by their porosity to some extent, the oil content of the samples with higher porosity is also higher, and the oil retention rate is generally higher; under dry friction conditions, the friction coefficient of the samples increases with the increase of porosity; under oil starvation lubrication conditions, the friction coefficient of porous samples decreases significantly compared with dense PEEK samples, exhibiting a good self-lubricating effect; the dense PEEK samples exhibit the best tensile strength, while the tensile strength of porous samples is closely related to their porosity and is synergistically influenced by effect of porogenesis.
