Improvement of adhesive properties and load capacity of the lubricant layer of friction units


The results of development of the technologies ensuring an increase of wear resistance, lowering of noise and vibration level in frictional units are discussed in the paper. The most efficient technologies of formation of fluorinated microsized films on the friction surface improving the wear resistance, contact fatigue and durability of connection of the lubricant layer with friction surfaces; molecular reinforcement of surface defects decelerating the development of fatigue damages; the effect of multilubrication improvng adhesion and load characteristics of the lubricant layer, its absorbing capacity, etc. are determined. The technology of formation of fluorinated films is implemented by the introduction of graphite fluoride additive to lubricant oil. In the case of molecular reinforcement the effect of increasing wear resistance and contact endurance is connected with the passivation of surface defects formed in final treatment. Defect passivation is realized by dipping of the processed details in the oil containing solid particles in the resonant mode. In the case of multilubrication the effect of creating an underlayer of lubricant on the basis of a highly adhesive material, for example, of polimetilsiloksan produced by the JSC «TogliattiAzot» is realized. The creation of a low frequency cavitational method and installations for washing parts of friction units at the «Nadezhnost» Research and Development Center of SSTU is a important collateral development. The first installations are implemented at the JSC «Progress» Space–Rocket Center and the JSC «Aviaagregat» of the «Tekhnodinamika» Holding.
