Abstract:The components of the imported silver and stibium bonded solid lubricant coating was investigated by FTIR spectra and XRD,and that the coating was composed of phenolic resin,graphite,stibous oxide and silver.Two kinds of bonded solid lubricant coatings named THC 800 and F44 were prepared according to the components of the imported silver and stibium coating,and their tribological properties were investigated by CSM friction tester under dry friction and MHK-500A friction wear tester under RP-3 aviation kerosene lubrication,respectively.The results show that the wear life of THC-800 coating achieves a greater than 540 minutes at the load of 15 N,the vibration amplitude of 1.25mm and the frequency of 10 Hz,while the wear life of F44 coating is only 220 minutes,and their friction coefficient is 0.075 and 0.080,respectively.The abrasive resistance of the THC-800 coating and F44 coating is 16.3km/μm and 11.8km/μm under oil lubrication at the load of 1120N and the sliding speed of 2.56m/s,and their friction coefficient is 0.076 and 0.080,respectively.THC-800 coating displays a lower friction coefficient and a longer wearing life compared to the F44 coating,which indicates that THC-800 coating possesses a better tribological properties than F44 coating.
