A method for producing piston rings, in particular compression piston rings, in which at least one main element is machined in such a way that a circumferential surface serving as a running surface is provide with a wear-resistant layer of a predeterminable layer thickness, wherein a number of piston ring, in particular compression piston rings, brought together to form an assembly, are machined cylindrically in the region of their circumferential surface, a wear-resistant electrodeposited layer of chrome is applied to the finished machined cylindrical circumferential surface, so that the wear-resistant layer has a constant layer thickness within the assembly as a whole, and subsequently the layer is machined in such a way as to produce a running surface that has a region of maximum layer thickness and at least one region of minimum layer thickness. |
