The 20 wt.% short glass fiber and 5 wt.% graphite reinforced polytetrafluoroethylene (PTFE) composite was prepared as the embedded solid lubricant, and the 40Cr steel and C86300 bronze were used as the backing material. The sliding tests were carried out on an oscillating tibometer under a contact pressure of 80 MPa and oscillating frequency of 0.14 Hz conditions at air. The results showed that the steel-based embedded solid lubricant composite against a 38CrMoAlA steel shaft exhibited low coefficient of friction and good wear resistance compared with the brass-based one. The major differences in tribological properties for the two composites arise from the different nature of 40Cr steel and C86300 bronze. The thermal softening of C86300 bronze occurs due to frictional heating leading to temperature rise and its strength drops rapidly in contrast to 40Cr steel. The present work is believed to be helpful for understanding of friction and wear behavior of different self-lubricating composites under heavy loading conditions.

In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
