A bonded solid lubricating coating was prepared by blended modification of the adhesives and combination of various fillers. The friction and wear behavior of the coating sliding against steel was simulated on a MM-200 test rig by changing the contact configuration of frictional pair. The coating shows better tribological behavior than two reference coatings and is applicable at high specific pressure and low and medium sliding speeds. It has the advantages of low friction, long service life, good thermal stability and convenience to storage.
