Abstrakt: In this study, practical recommendations for the production of aluminum coatings by the cold gas-dynamic spraying method (CGDS), as well as for the methods of aluminum coating strengthening by a ceramic component with the formation of a gradient structure, have been developed. The resulting ceramic-metal coatings have the following key optimization parameters: high adhesive strength (more than 70 MPa), high Vickers hardness (more than 480 MPa), and low porosity (less than 0.5%). These functionally graded coatings can be used to protect the elements and assemblies of machine-building equipment from wear. [ABSTRACT FROM AUTHOR]
