Title (EN) METHOD FOR PRODUCING A PISTON RING AND PISTON RING WITH REDUCED SHOCK PRESSURE
(FR) PROCÉDÉ DE PRODUCTION D'UN SEGMENT DE PISTON ET SEGMENT DE PISTON À PRESSION DYNAMIQUE RÉDUITE
(DE) VERFAHREN ZUR HERSTELLUNG EINES KOLBENRINGS SOWIE KOLBENRING MIT REDUZIERTEM STOSSDRUCK
Abstract:
(EN) The invention relates to a method for producing a piston ring (1) with reduced shock pressure, in which a base body (1') which is rectangular in the cross-section is subjected to a nitriding process in the region of all the outer surfaces thereof and subsequently in the region of the inner peripheral surface (4) of the base body (1'), at least one cross section modification (2) is carried out such that the respective cross-section modification (2) has no nitration layer.
(FR) L'invention concerne un procédé pour produire un segment de piston(1) à pression dynamique réduite, selon lequel un corps de base (1) de section transversale rectangulaire est soumis à un processus de nitratation dans la zone de toutes ses surfaces extérieures, au moins une modification de section transversale (2) étant ensuite pratiquée dans la zone de la surface périphérique intérieure (4) dudit corps de base (1), de manière que ladite modification de section transversale (2) ne comporte pas de couche de nitratation.
(DE) Verfahren zur Herstellung eines Kolbenrings (1) mit reduziertem Stoßdruck, indem ein im Querschnitt rechteckiger Grundkörper (1') im Bereich sämtlicher seiner äußeren Flächen einem Nitriervorgang unterzogen wird und anschließend im Bereich der inneren Umfangsfläche (4) des Grundkörpers (1') mindestens eine Querschnittsstörung (2) herbeigeführt wird, dergestalt, dass die jeweilige Querschnittsstörung (2) keine Nitrierschicht aufweist.
