Gas-detonation sputtering of piston ring coatings for internal combustion engines by SVS-mechanocomposites based on titanium carbide

There are considered ecologically harmless technologies for nano-structural material obtaining by methods of mechanochemistry with carrying out a reaction of high-temperature synthesis in a metal matrix for the application of the powder material obtained in the course of gas-detonation coating processes which may substitute electroplate chromium coating. As a sputtered powder there was used SVS- mechanocomposite having Ti-C-NiCr in its composition. It is determined that the wear of piston rings with the developed coating is lower by 27%, than in similar rings with an electroplate chromium coating.
