Abstract

A turbocharger is a unit of modern internal combustion engines designed to boost it. Since a drive of the turbocharger is most often carried out from the energy of the exhaust gases, the conditions of its operation can not be called favorable: the temperature of the exhaust gases sometimes reaches 7000C, high chemical activity of the exhaust gases, high speed of rotation of the turbine. The consequence of difficult operating conditions is the wear of its elements. One of the main causes of wear of the active elements of the turbocharger is abrasive wear. Various methods of restoration and strengthening can be used to restore machine parts. However, not all methods can provide the necessary resource for the restoration and strengthening of parts working in abrasive and corrosive environments. One of the modern directions of increasing the wear resistance and other properties of reducing coatings is the use of composite materials. This article presents the results of research on the development of a new method for restoring and strengthening parts with composite materials based on the use of chemical vapor deposition of metals CVD - method (Chemicikal Vapor Deposition) by decomposition of organometallic compounds. It is shown that the developed composite material obtained by the CVD-method of decomposition of organometallic compounds provides an increase in wear resistance of at least 2.0...2.2 times in comparison with new parts composite material. Vapor-phase deposition of metals, Chemicikal Vapor Deposition-method, decomposition of organometallic compounds.

Keywords
