A lubricating layer is applied to the surface of an engine component using an adhesion promoting layer between the lubricating layer and the material of the engine component. Process for applying a lubricating layer to the surface of the engine component comprises: (a) placing the engine component (1) provided with an adhesion promoting layer (3) into a reactor, and adhering the lubricating layer (5) to the material of the engine component (1) through the adhesion promoting layer; (b) evacuating the reactor (6) to a pressure of less than 100 mbar, preferably less than 10 mbar and/or partially filling the reactor with inert gas; (c) introducing a process gas containing boron, nitrogen and/or carbon as a compound; (d) adding a second starting material to the liberated gas phase, the material containing boron as a compound and which releases boron under process conditions; (e) adding a first starting material to the liberated gas phase, the material containing oxygen as a compound and which releases oxygen under process conditions; (f) manufacturing an intermediate layer (4) with the starting materials on the adhesion promoting layer (3); and (g) reacting boron and oxygen in the intermediate layer (4) to form boric acid as dry lubricant of the lubricating layer (5) with the aid of hydrogen.
