Abstract
A new type of composite material stainless steel fiber and carbon fiberreinforced polyetheretherketone PEEK was investigated to study its friction and wear properties and mechanisms The friction materials containing 11 ingredients were hotpressed and tested using a padondisc type wear tester under unlubricated sliding friction and wear conditions at a constant sliding speed The worn surface morphology was observed by Fieldemission Scanning Electron Microscope FESEM and Atomic Force Microscope AFM The role of transfer film was studied using Xray photoelectron spectroscopy XPS to investigate the thermal decomposition of the friction material The fade ratio of the composites was only 48 the recovery ratio 107 and the total wear ratio was as low as 099 × 10−7 cm3N m−1 showing the perfect properties of heat stability and recovery as well as high antiwear ability of the composites Adherence abrasion and particle abrasion take place at higher temperature A transfer film is formed which may improve abrasive resistant performance to get stable friction coefficient and low abrasion value for composite friction materials
