A method of forming a plasma multilayer composite coating from components with different physical and mechanical characteristics includes operations of spraying a coating of a certain
thickness by sequentially applying layers of material, the first layer applied to the surface of the base being a metal component, the other layers being fed into the plasma flow separately with a flow rate that gradually changes. The first layer of the coating is locally melted and welded to the substrate due to the periodic initiation of an electric arc between the plasma torch and the substrate from an additional power source, all subsequent layers of the coating are formed from a mixture of components with a gradual decrease in the content of the metal component of the first layer.
