Approbation of a structural approach mode for optimization producing coatings, increases the wear resistance of the turbine blades
A complex analysis of the benefits of using a vacuum-plasma coatings to increase wear steam turbine components. The possibility of using a structured approach to surface engineering to monitor the efficiency used in the preparation of coatings, physical and tech- nological parameters. As express structural parameters control the functional properties of the nitride coating with an fcc crystal lattice is proposed to use the degree of texturing to the [111] axis perpen- dicular to the growth surface, and the average size of the crystallites. It is shown that the use of high-voltage pulse stimulation technol- ogy to streamline the formation mononitride coatings, as well as multi-element nitrides highentropy alloys can increase the hardness of coatings by more than 1.5 times, and the abrasion resistance in- creased more than 1.7 times, compared with coatings currently used to protect the blades from wear and friction-slip gas turbine units.
