摘要： A piston ring, is produced by providing, on the radially outer circumferential surface of a ring-shaped metallic main body, a recess, the metallic main body having a radially outer circumferential surface, a radially inner circumferential surface, and flank surfaces interposed therebetween providing the recess with a contour that deviates from a cylindrical shape at least on the bottom of the recess, providing at least one wear-resistant layer on the outer circumferential surface, including the recess, and at least partially removing an area of the at least one wear-resistant layer on the outer circumferential surface and including an area corresponding to a scraping edge, thereby forming a land having a predefinable width.

摘要： A piston ring, in particular a compression piston ring, includes a running surface, upper and lower flank areas, an inner peripheral area and a joint. The wall thickness of the piston ring is uniform over its periphery and at least the running surface is provided with a PVD coating or a CVD layer in such a manner that the running surface layer has a lesser layer thickness in the peripheral area close to the joint than in the remaining peripheral area of the running surface.

摘要： A method for producing a recessed steel piston ring provided with a wear-resistant layer includes generating a main body that has a recess on the running surface side and that, in the region where a lower flank of the main body transitions into the running surface is worked so that a chamfer is created, providing the running surface and at least portions of the chamfer with at least one wear-resistant layer, nitriding the circumferential surface and the lower and upper flanks of the main body that are not provided with the wear-resistant layer so that a section having a defined width and having no nitride layer remains on the flank adjacent the chamfer, and removing the at least one wear-resistant layer to such an extent that a substantially sharp, but unnitrided functional edge is created in the region where the lower flank transitions into the running surface.
