Abstract

The surface layer to form a running surface on a cylinder wall contains several phases of components which are separated from the phase(s) of the remaining surface cladding material. The surface layer is applied by a plasma spray as a powder with an iron content, which carries all the components of the surface coating.

Description

Die Erfindung betrifft eine gemäss dem Oberbegriff des Anspruchs 1 ausgebildete Oberflächenschicht zur Bildung einer Lauffläche auf einer Zylinderwandung, ein im Oberbegriff des Anspruchs 8 definiertes Spritzpulver zur Erzeugung der Oberflächenschicht sowie ein im Oberbegriff des Anspruchs 18 umschriebenes Verfahren zur Erzeugung solcher Oberflächenschichten.The invention relates to a trained according to the preamble of claim 1 Surface layer to form a tread on a cylinder wall, an im Preamble of claim 8 defined spray powder for producing the surface layer and a method for generating circumscribed in the preamble of claim 18 such surface layers.

Das thermische Beschichten von Zylinderlaufflächen mittels Plasmaspritzverfahren ist bereits bekannt, z.B. aus der Veröffentlichung EP-B1-0 716 156, "Brennkraftmaschinenblock mit beschichteten Zylinderbüchsen".The thermal coating of cylinder running surfaces by means of plasma spraying is already known, e.g. from publication EP-B1-0 716 156, "Internal combustion engine block with coated cylinder liners ".

Die Zerspanbarkeit solcher Plasmaspritzschichten durch Honen, Läppen, Feinspindeln oder Schleifen war jedoch bis anhin beschränkt, so dass die Bearbeitungskosten relativ hoch lagen, insbesondere was die Bearbeitungszeit und die Lebensdauer der Werkzeuge anbelangt.The machinability of such plasma spray coatings by honing, lapping, fine spindles However, grinding has been limited so far, making processing costs relative were high, especially in terms of machining time and tool life As.

Die Zerspanbarkeit solcher Plasmaspritzschichen kann durch Zugabe von Festschmierstoffen deutlich erhöht werden, z.B. durch Zugabe von hexagonalem Bornitrid BN, von MoS2 oder von WS2. Bornitrid und die genannten Sulfide lassen sich jedoch nur schlecht in die Schichten einbringen, weil sie mit dem Sauerstoff der Luft reagieren oder durch die hohe Temperatur des Plasmas zersetzt werden. Sie müssen durch kostspielige Umhüllung geschützt werden.The machinability of such plasma spray layers can be increased significantly by adding solid lubricants, for example by adding hexagonal boron nitride BN, MoS 2 or WS 2 . However, boron nitride and the sulfides mentioned can only be introduced into the layers with difficulty because they react with the oxygen in the air or are decomposed by the high temperature of the plasma. They have to be protected by expensive wrapping.

Weiter ist in der Patentanmeldung EP 99 81 1122.3 ein Verfahren zum sog. "Reaktivspritzen" beschrieben, bei welchem durch kontrollierte Sauerstoffzugabe während des Plasmaspritzens in der Plasmaspritzschicht FeO- (Wustite) und Fe3O4-Kristalle (Magnetite) gebildet werden. Dadurch werden der Reibungskoeffizient und die Zerspanbarkeit verbessert.Furthermore, the patent application EP 99 81 1122.3 describes a method for so-called "reactive spraying", in which FeO (wustite) and Fe 3 O 4 crystals (magnetite) are formed in the plasma spray layer by controlled addition of oxygen during the plasma spraying. This improves the coefficient of friction and machinability.

Schliesslich sind aus der GB-A-2 297 053 Einsatzbüchsen für Zylinderlaufflächen bekannt, welche aus supereutektischen Aluminium/Silizium-Legierungen bestehen. Die Einsatzbüchse wird nach dem Einsetzen in den Motorblock einer mechanischen Bearbeitung unterzogen, indem deren Oberfläche zuerst grob und dann fein bearbeitet wird. In einer letzten Bearbeitungsphase wird die Oberfläche gehont. Nach dem Hohnen stehen diejenigen Partikel, die härter sind als die Mikrostruktur der Basislegierung, namentlich Silikon Kristalle und intermetallische Phasen, etwas über die eigentliche Oberfläche vor. Durch diese exponierten Partikel soll die Verschleissfestigkeit verbessert werden.Finally, from GB-A-2 297 053 insert liners for cylinder running surfaces are known, which consist of super eutectic aluminum / silicon alloys. The Insert sleeve is subjected to mechanical processing after being inserted into the engine block subjected to a first rough processing and then finishing. The surface is honed in a final processing phase. Stand after honing those particles that are harder than the microstructure of the base alloy, namely Silicon crystals and intermetallic phases, slightly above the actual surface in front. These exposed particles are said to improve wear resistance become.
