Abstract

The present invention relates to a method for applying hexagonal boron nitride to a rough surface, wherein it is intended for the boron nitride to be provided as a temperature-resistant lubricant of the surface. According to the invention, a pin composed of hexagonal boron nitride is rubbed with pressure over the rough surface, such that abraded boron nitride adheres to the surface.

Claims (2)

1. Method for applying hexagonal boron nitride as lubricant onto a surface of bayonet slits of a confinement ring of an ARC source, characterized in that hexagonal boron nitride is prepared in the form of a solid piece and this solid piece is rubbed over the surface to be lubricated in such a manner that boron nitride components are abraded from the solid piece and adhere to the surface as abrasion.

2. Method according to claim 1 , characterized in that the solid piece is obtained essentially through sintering of hexagonal boron nitride.
