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 11):
A physical vapor deposition method for coating a piston ring of an internal-combustion engine, comprising:\n attaching at least one piston ring to a turntable such that an opening of the at least one piston ring is positioned in front of at least one source of coating material; performing a first rotational movement of the turntable about a central axis of the turntable; receiving a first deposition of coating material on the at least one piston ring in a region of a peripheral surface of the at least one piston ring defined by a 180\u00b0 circumferential angle disposed adjacent to a center of the opening while performing the first rotational movement; performing the first rotational movement of the turntable while performing a second rotational movement of the at least one piston ring on the turntable; and causing, via the at least one source of coating material, a second deposition of coating material around the entire peripheral surface defined between a circumferential angle of 0\u00b0 and 360\u00b0 of the at least one piston ring, while performing the first rotational movement and performing the second rotational movement; wherein receiving the first deposition of coating material and causing the second deposition of coating material are alternatingly performed; and wherein the first rotational movement and the second rotational movement are in opposite directions.
