Abstract
(DE)
Die vorliegende Erfindung betrifft eine Verschleißschutzschicht, die vorzugsweise bei Kolbenringen von Verbrennungskraftmaschinen Verwendung findet. Die Verschleißschutzschicht umfasst: 15 - 25 Gew.% Eisen (Fe), 10 - 25 Gew.% Wolframkarbid (WC), 30 - 40 Gew.% Chrom (Cr), 10 - 25 Gew.% Nickel (Ni), 10 - 25 Gew.% Molybdän (Mo), 1-10 Gew.%) Kohlenstoff (C), 0,1-2 Gew.%> Silizium (Si), wobei Cr in elementarer Form und/oder als Karbid in Form von Cr2C3 vorliegt. Darüber hinaus sind ein Verfahren zum Auftragen der Verschleißschutzschicht und ein Kolbenring mit derartiger Verschleißschutzschicht offenbart.
(EN)
The present invention relates to a wear protection layer which is preferably used for piston rings of internal combustion engines. The wear protection layer comprises: 15-25% by weight of iron (Fe), 10-25% by weight of tungsten carbide (WC), 30-40% by weight of chromium (Cr), 10-25% by weight of nickel (Ni), 10-25% by weight of molybdenum (Mo), 1-10% by weight of carbon (C), 0.1-2% by weight of silicon (Si), where Cr is present in elemental form and/or as carbide in the form of Cr2C3. In addition, a process for applying the wear protection layer and a piston ring having such a wear protection layer are disclosed.
