To solve the problem of improving the wear and corrosion resistance of parts in mechanical engineering, the method of gas-thermal spraying of coatings is often used. The process of gas-thermal spraying makes it possible to obtain a protective coating by atomizing molten or heated material using a high-speed gas or plasma flow. As part of the study, a mathematical model describing the physical processes occurring during the spraying process was developed. The mathematical model makes it possible to determine the optimal modes of the process, providing the obtaining of coatings of a given thickness and properties. The developed mathematical model will allow process engineers to calculate process parameters more accurately and obtain coatings with specified characteristics. The maximum adhesive strength of the gas-thermal coating Х18Н10Т (4.78 MPa) is observed at the maximum difference between the burner nozzle area and the sprayed area.
