Information × Registration Number 0207U008561, 0107U008288 , R & D reports Title Development of technology of increase of longevity of knots of friction of combustion and transmissions of car engine due to modification of superficial layers of metal popup.stage_title Head Dmytrichenko Nikolay, Registration Date 17-12-2007 Organization Ukranian Transport University popup.description2 Kinetics of change of actual area of contact, thickness of scope adsorption layers and intensity of wear after the period of earning extra money depending on the initial roughness of surfaces of friction is certain. Contact surfaces are the most optimum pairs of friction with an initial roughness 0,7 mkm. In the period of earning extra money, activating of superficial layers of metal provides forming of proof scope adsorption layers tolshinoy 0,45 mkm (from them on SOP is 0,15 - 0,25 mkm) on all area of surface of contact, that provides the decline of intensity of wear on 46%. It should be noted that if in the period of earning extra money the border mode of lubricating action (l = 0,86) prevails, forming of scope layers of lubricating material and establishment of optimal roughness of contact surfaces provides realization in the contact of the mixed mode of friction (l = 1,95).
