Abstract:
A piston ring may include a drawn metal base of constant thickness having an outer peripheral surface. The piston ring may also include a hard coating disposed on the outer peripheral surface. The coating may have a thickness that is greater in a region of two butt ends of the base than a thickness of the coating in another region of the outer peripheral surface. The coating may be defined by a plurality of layers with a nanoscale structure.

Claim (Index 6):
The piston ring as claimed in  claim 1 , wherein a thickness gradient of the coating is at least 15 \u03bcm at a circumferential angle of 90\u00b0 and 270\u00b0 of the base and is at least 55 \u03bcm in the region of the two butt ends, and wherein the two butt ends define an opening of the base.
