abstract

One of important factors, determining of the reliability of tribocontacts, is their good lubrication. That is why the paper discusses a number of questions affecting the wear: a base oil type and wear resistant coatings (a Cr layer) and a layer working as a solid lubricant after chemical and thermal processing, deposited on piston rings. As lubricating compositions with different trbotechnical compounds (TC) are widely used today for lubricating tribocontacts in internal combustion engines of all types, the paper contains the information on how different mineral TC affect the work of tribocontacts that simulate rather conditions of cylindro-piston group (CPG) in today’s high- augmented engines. The results of the investigation on the comparative evaluation of wear resistance and tribotechnical characteristics made for 6 variants of friction contact lubrication (gray cast iron–electroplated chromium, steel–steel, steel–aluminium), carried out on a test bed simulating hard condition of boundary friction typical for CPG parts working in augmented engines, show any positive influence on the CPG operation for TC by type written in Patent RF 2188227 (2002 y.). Researches of a friction surface state were carried out with employment of such methods as Auger electron spectroscopy. The analysis of received results makes it possible to come to next conclusion: – The processing of friction surfaces by mineral TC improves antifriction and anti-wear properties of different tribocontacts differently, forming in each event different modified layers (by a composition and a thickness within 50–20000 A), having different wear resistance.
