摘要:
A piston ring is produced by providing a metallic main body, at least including a radially outer running surface, a radially inner circumferential surface and upper and lower flank surfaces interposed therebetween, with a defined taper in the region of an approximately cylindrical running surface, providing at least the running surface with at least one wear-resistant layer, and removing the at least one wear layer in the region of the entire circumference of the ring that forms a scraping edge forming a land having a predefinable width.
