The article is devoted to the problem of increasing reliability and a service life of the cylindrical hinge for turning the blades of a guide axial compressor of aircraft engines under sliding friction without lubrication. The prospects of using nanostructured crystals of zirconium dioxide partially stabilized by yttrium oxide are justified. High anti-friction properties of the hinge are provided by the selection of the counterface material. Particular attention is paid to the resistance to scoring of the studied friction pairs. It has been established that the most promising counterfaces for the crystals of zirconium dioxide are molybdenum selenide coatings and alpha-titanium alloys.
