Development of technology of surface hardening of bearing parts from medium-carbon steels using chemical-thermal treatment and applying nitride coatings
New twolayer compositions formed as a result of carbonitration or nitriding of the steel substrate and subsequent coating of the TiAlN type are obtained by chemicalthermal treatment and reactive magnetron sputtering. Their structure and properties are investigated. The results of practical application of the developed compositions for strengthening of precision parts of friction pairs and of other purposes are presented.
