## 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

### Claim 1

Method for applying hexagonal boron nitride as lubricant onto a surface, 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.

### Claim 2 (depends on 1)

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

### Claim 3 (depends on 1)

Method according to claim 1, characterized in that the abrasion is achieved through rubbing with a pressure of at least 5 bar, preferably between 10 bar and 40 bar and even more preferably with a pressure of 30 bar.

### Claim 4 (depends on 1)

Application of the method according to claim 1, on bayonet slits of a confinement ring of an ARC source.

### Claim at position 5

5-8. (canceled)
