Abstract
Der Ringkörper eines Kolbenrings ist über seine gesamte Oberfläche mit einer nitrierten Schicht versehen, welche sich aus einer Diffusionsschicht und einer darüber liegenden Verbundschicht zusammensetzt. An der äußeren Umfangsfläche des Ringkörpers ist die Verbundschicht oder die gesamte nitrierte Schicht entfernt, und auf der dadurch freigelegten Diffusionsschicht bzw. Oberfläche des Kolbenringkörpers ist eine plattierte oder aufgespritzte Schicht ausgebildet.The ring body of a piston ring is provided over its entire surface with a nitrided layer, which is composed of a diffusion layer and an overlying composite layer. The composite layer or the entire nitrided layer has been removed from the outer circumferential surface of the ring body, and a plated or sprayed-on layer is formed on the diffusion layer or surface of the piston ring body exposed thereby.
Claims (2)
Einsatz gewährleistetThe invention is based on the object of designing a piston ring of the type explained at the beginning in such a way that, while being simple to manufacture, it has a low-wear 40 even under unfavorable operating conditions
Commitment guaranteed
Merkmale des Patentanspruchs 1 gelöst.According to the invention, this object is achieved in the case of a generic piston ring by the characterizing features
Features of claim 1 solved.
Umfangsfläche und Aufbringen der plattierten oder aufgespritzten Schicht direkt auf die Diffusionsschicht besteht für die äußere Umfangsfläche der Kolbenringe ein
sehr effektiver Schutz, der eine hohe Lebensdauer des
Kolbenringes sicherstellt, da diese Schicht sehr ver- 50
schleißfest ist und auf der Diffusionssc.hicht sehr gut
haftet. Eine durch die Reibung zwischen der Verbundschicht und einer Zylinderwand hervorgerufene übermäßige Abnutzung, insbesondere Rauhübnutzung, wird
damit wirksam verhindert. 55By removing the composite layer on the outer 45
The circumferential surface and application of the plated or sprayed-on layer directly onto the diffusion layer exist for the outer circumferential surface of the piston rings
very effective protection that ensures a long service life of the
Piston ring ensures that this layer is very sensitive
is wear-resistant and very good on the diffusion sc
adheres. Excessive wear, particularly rough wear, caused by the friction between the composite layer and a cylinder wall
thus effectively prevented. 55
durch Patentanspruch 2 charakterisiert. Die aus einer
Dispersion von diskreten Teilchen in einer Plattierungsmatrix gebildete Schicht ist auch unter ungünstigen Betriebsbedingungen besonders hatlbar und Widerstands- 60
fähig.An advantageous development of the piston ring is
characterized by claim 2. The one from a
Dispersion of discrete particles in a plating matrix layer is particularly resistant and resistant even under unfavorable operating conditions
able to.
