Development of the Composition and Modes of Spraying Antifriction Coating Reinforced with Quasicrystals for the Manufacture of Sliding Bearings

Abstract

The paper presents the compositions of coatings from composite materials reinforced with quasicrystals. The composition and mode of application of cold gas-dynamic deposition of antifriction coating based on composite materials reinforced with quasicrystals for the manufacture of sliding bearings have been determined and determined. Quasicrystals of the Al-Cu-Fe system, metal composite coatings based on copper reinforced with quasicrystal line particles were used for research. In the course of the work, the compositions of quasicrystal-reinforced coatings were developed, the optimal composition and modes of applying the coating by cold gas-dynamic spraying were determined. According to the optimal mode, samples were made and their mechanical and tribological properties were investigated.
