A lubricating layer is applied to the surface of a slide tappet using an adhesion promoting layer between the lubricating layer and the material of the tappet. Applying a lubricating layer to the surface of the slide tappet comprises: (a) placing the slide tappet (1) provided with an adhesion promoting layer (3) into a reactor, and adhering the lubricating layer (5) to the material of the valve clamping washer (1) through the adhesion promoting layer; (b) evacuating the reactor to a pressure of less than 100 mbar, preferably less than 10 mbar and/or partially filling the reactor with inert gas; (c) adding a second starting material to the liberated gas phase, the material containing boron as a compound and which releases boron under process conditions; (d) adding a first starting material to the liberated gas phase, the material containing oxygen as a compound and which releases oxygen under process conditions; (e) manufacturing an intermediate layer (4) with the starting materials on the adhesion promoting layer (3); and (f) 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.
