FIELD: process engineering.
SUBSTANCE: invention relates to production of piston ring with axial height <2 mm. Piston ring has at least one rib, radially outer working surface, radially inner peripheral surface as well as top and bottom side surfaces extending there between. Note here that appropriate rib is provided with outline conically converging radially outward. Then, working surface and side surfaces of appropriate conical rib are coated with at least one wear-proof ply. Thereafter solely side surface making the scraping edge of appropriate rib is subjected to at least partial removal of material.
EFFECT: higher reliability of piston ring.
