Abstract:
A method for an external and adhesive application of a lubricant layer to an exposed, frictionally stressed surface of an object, said method comprising:applying an adhesion-promoter layer to the exposed surface of the object; introducing the object with the applied adhesion-promoter layer into a reactor; at least one of evacuating the reactor to a pressure of less than 100 mbar or partly filling the reactor with an inert gas; adding a first precursor material containing boron to a depositing gas phase; adding a second precursor material containing oxygen to a depositing gas phase; producing an intermediate layer comprising said first and second precursor materials on the adhesion-promoter layer; and forming a lubricant layer to function as a dry lubricant by at least partially converting boron and oxygen in the intermediate layer at least in a region of its freely accessible surface to form boric acid in the presence of hydrogen.
