INFLUENCE OF SMALL SILICON ADMIXTURES ON THE WORKING PERFORMANCES OF NITRIDE-TITANIUM COATINGS

It is shown, that small silicon admixtures (to 3 %) in coatings on the basis of titanium nitrides lead to the considerable changes of performances (resistance against the wear and the ion sputtering, erosion resistance, a roughness) of deposited condensates in comparison with coatings on the basis of "pure" titanium nitrides. So, with growth of concentration of silicon in the coatings, the resistance against the wear and the ion sputtering raises, and resistance against cavitation decreases. Presence of essential interior stresses in the coatings synthesised in the field of pressures of nitrogen nearby 10(-3)Torr, leads to restrictions on the limiting thickness of condensates owing to occurrence of surface fragments exfoliations.
