- To solve the lubricating problems of spherical plain bearings under high-low temperature, high vacuum, heavy loads and strong oxidation conditions, the PTFE and MoS2 based lubricating coatings were prepared on the inner rings of the spherical plain bearings by spraying technique. A self-made tribo-tester was used to investigate the friction coefficient, wear loss, and friction temperature increase of bearings with coatings under different oscillation frequencies. Using scanning electron microscope (SEM) and energy dispersive X-ray spectroscopy (EDS), the worn surfaces of the coatings and the counter surfaces were characterized and analyzed. The results showed that PTFE and MoS2 based lubricating coatings significantly improved the tribological properties of the spherical plain bearings. The tribological performance of PTFE based coating was obviously superior to MoS2 based coating and its wear mechanism was adhesive wear. However, the MoS2 based coating mainly occurred severe adhesive wear and abrasive wear, and the tribological properties of spherical plain bearings with MoS2 coating were relatively optimal under low frequencies. This paper provides a reference to developing new lubricating techniques for the spherical plain bearings.
