Description
Die vorliegende Erfindung betrifft ein Gleitelement, insbesondere einen Kolbenring, für eine Verbrennungskraftmaschine, sowie ein Herstellungsverfahren für ein solches Gleitelement.The present invention relates to a sliding element, in particular a piston ring, for an internal combustion engine, and a manufacturing method for such a sliding element.
Ziel der Erfindung ist es, die tribologischen Eigenschaften von thermisch gespritzten Kolbenringen mit einem bisher nicht verwendeten Materialsystem als Beschichtungsmaterial im Vergleich zu Kolbenringbeschichtungen, die mittels galvanischer Verfahren oder thermischen Spritzens hergestellt werden, zu verbessern.The aim of the invention is to improve the tribological properties of thermally sprayed piston rings with a previously unused material system as a coating material in comparison to piston ring coatings, which are produced by means of electroplating or thermal spraying.
Chrom-basierte Beschichtungen, aufgetragen mittels thermischen Spritzens, finden noch keine Anwendung auf Kolbenringen. Chromhaltige Schichtsysteme werden heutzutage mittels galvanischer Prozesse auf Kolbenringe aufgetragen. Zusätzlich werden Metalloxid-oder Diamantpartikel während des Prozesses in die Chromschichten eingelagert, um den Verschleißwiderstand zu verbessern.
Eine Alternative zu den mit Metalloxid- oder Diamantpartikeln verstärkten Chromschichten, die mittels galvanischer Prozesse hergestellt werden, ist das Beschichten von Gleitelementen mit chrombasierten Materialien mittels thermischen Spritzens. Die Hartstoffpartikel zur Verschleißreduzierung sind bei der thermisch gespritzten Schicht Chromkarbide (Cr3C2).An alternative to the metal oxide or diamond particles reinforced chromium layers, which are produced by means of galvanic processes, is the coating of sliding elements with chromium-based materials by means of thermal spraying. The hard material particles are to reduce wear (Cr 3 C 2) in the thermally sprayed layer chromium carbides.
Die Verwendung von Cr-basierten Schichtsystemen mit Chromkarbiden als Kolbenringbeschichtungsmaterial, hergestellt mittels Plasmaspritzen oder Hochgeschwindigkeits-Flammspritzen (high velocity oxy fuel, HVOF), führt zu der Herstellung eines neuen Kolbenringtyps.The use of Cr-based chromium carbide layer systems as the piston ring coating material produced by plasma spraying or high velocity oxy fuel (HVOF) results in the production of a new type of piston ring.
