Description
Die Erfindung betrifft ein Spritzpulver für die Herstellung von verschleissfesten Beschichtungen auf den Lauf- und Reibungsflächen gleitender Reibung ausgesetzter Maschinenteile, wie insbesondere von Kolbenringen in schnellaufenden Dieselmotoren, den Reibflächen von Synchronringen oder den Feuerstegen von Kolbenböden der Kolben in Verbrennungskraftmaschinen durch vorzugsweise ein Plasmaspritzverfahren.The invention relates to a wettable powder for the production of wear-resistant coatings on the running and friction surfaces of sliding friction from exposed machine parts, such as in particular piston rings in high-speed diesel engines, the friction surfaces of synchronizer rings or the top land of piston heads of the pistons in internal combustion engines, preferably by a plasma spraying process.
Zur Erhöhung der Verschleissfestigkeit werden in der Praxis die Laufflächen gleitender Reibung ausgesetzter Maschinenteile vor allem mit galvanischen Hartchromschichten oder mit thermisch aufgespritzten Schutzüberzügen aus vorzugsweise Metallen oder Metallegierungen versehen. Zur Beschichtung vor allem der Laufflächen von Kolbenringen für Verbrennungskraftmaschinen hat sich als Spritzwerkstoff vor allem Molybdän hervorragend bewährt. Das Molybdän wird dabei entweder ganzflächig aufgetragen, und man spricht von Überzügen in überspritzter Form, oder es werden Nuten und Ausnehmungen in die Laufflächen eingearbeitet, die dann mit dem Spritzwerkstoff ausgefüllt werden, und man spricht dann von Beschichtungen in ein- oder beidseitig gekammerter Form.In practice, to increase the wear resistance, the running surfaces of machine parts exposed to sliding friction are provided primarily with galvanic hard chrome layers or with thermally sprayed protective coatings made of preferably metals or metal alloys. Molybdenum, in particular, has proven to be an excellent spray material for coating the running surfaces of piston rings for internal combustion engines. The molybdenum is either applied over the entire surface and one speaks of coatings in overmolded form, or grooves and recesses are worked into the treads, which are then filled with the spray material, and one then speaks of coatings in one or both sides chambered form.
Molybdänspritzschichten besitzen vor allem eine hervorragende Brandspurfestigkeit, während ihre Verschleissfestigkeit der von galvanischen Hartchromschichten unterlegen ist. Zusätzlich sind Molybdänspritzschichten relativ spröde, so dass vor allem bei extremen Belastungen die Gefahr von Schichtausbrüchen sowohl bei gekammerten als auch bei überspritzten Ringen besteht.Above all, molybdenum spray coatings have excellent fire resistance, while their wear resistance is inferior to that of galvanic hard chrome coatings. In addition, molybdenum spray layers are relatively brittle, so that there is a risk of layer breakouts, especially in the case of extreme loads, both in the case of chambered and overmolded rings.
Deshalb hat man vor allem zur Verbesserung der Verschleissfestigkeit derartiger Schichten versucht, dem Molybdän andere Elemente zuzulegieren oder zuzumischen, und man hat zusätzlich Hartstoffe den Spritzpulvern hinzugefügt. Nach der Literaturstelle «Schweisstechnik», 27, Band 9 (1977), Seiten 396 und 399, werden durch Plasmaspritzen verschleissfeste Schichten aus Molybdän und Molybdänkarbid hergestellt. Die Spritzpulver der DE-AS 2433814 bestehen aus Molybdän mit 0,5 bis 45% Eisen, Kobalt, Nickel, Titan, Vanadium, Chrom, Aluminium, Wolfram, Tantal, Rhenium und/oder Zirkonium sowie 0,8 bis 10% Silizium, und nach der DE-OS 2841 552 sind dem Molybdän 3 bis 40% Aluminiumlegierung zugemischt. Beide Spritzpulver können zusätzlich gegebenenfalls Hartstoffe auf der Basis von Karbiden, Nitriden, Oxiden und/oder intermetallischen Verbindungen enthalten. Diese Massnahmen erbrachten vor allem eine Verbesserung der Verschleissfestigkeit der Spritzschichten; mit Verbesserung der Verschleissfestigkeit büssten derartige Schichten einen Teil ihrer Brandspurfestigkeit ein, oder die Schichten wurden spröder, so dass es bei extremen Belastungen sogar vermehrt zu Schichtausbrüchen kam.For this reason, attempts have been made, above all to improve the wear resistance of such layers, to alloy or add other elements to the molybdenum, and hard materials have also been added to the wettable powders. According to the literature reference "Welding Technology", 27, Volume 9 (1977), pages 396 and 399, wear-resistant layers of molybdenum and molybdenum carbide are produced by plasma spraying. The wettable powders of DE-AS 2433814 consist of molybdenum with 0.5 to 45% iron, cobalt, nickel, titanium, vanadium, chromium, aluminum, tungsten, tantalum, rhenium and / or zirconium and 0.8 to 10% silicon, and According to DE-OS 2841 552, 3 to 40% aluminum alloy is mixed with the molybdenum. Both wettable powders may additionally contain hard materials based on carbides, nitrides, oxides and / or intermetallic compounds. These measures primarily brought about an improvement in the wear resistance of the spray coatings; With an improvement in the wear resistance, such layers lost part of their fire resistance, or the layers became more brittle, so that there was even an increase in layer breakouts under extreme loads.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, Spritzpulverzusammensetzungen zu finden, aus denen sich durch thermische Spritzverfahren verschleissfeste Beschichtungen auf insbesondere den Laufflächen von reibender Beanspruchung ausgesetzten Maschinenteilen in überspritzter und in ein- oder beidseitig gekammerter Form herstellen lassen, die zugleich eine verringerte Sprödigkeit und damit eine verbesserte Ausbruchsicherheit aufweisen, ohne dass die Brandspursicherheit wesentlich herabgesetzt ist. Die Spritzpulver sollen sich insbesondere zur Beschichtung von Kolbenringen in schnellaufenden Dieselmotoren eignen.The present invention is therefore based on the object of finding wettable powder compositions from which wear-resistant coatings can be produced on machine parts exposed to rubbing stress, in particular in overmolded and chambered form on one or both sides, by thermal spraying processes, which at the same time have a reduced brittleness and thus have improved outbreak security without significantly reducing fire trail security. The wettable powders are said to be particularly suitable for coating piston rings in high-speed diesel engines.
Erfindungsgemäss wird diese Aufgabe durch ein Spritzpulver gelöst, welches aus den drei Komponenten 20 bis 60 Gewichtsprozent Molybdän, 20 bis 50 Gewichtsprozent Molybdänkarbid und bis zu 30 Gewichtsprozent einer niedrig schmelzenden Legierung auf der Basis einer Chromlegierung, einer Chromnickellegierung und/oder einer Aluminiumlegierung besteht.According to the invention, this object is achieved by a wettable powder which consists of the three components 20 to 60 percent by weight of molybdenum, 20 to 50 percent by weight of molybdenum carbide and up to 30 percent by weight of a low-melting alloy based on a chromium alloy, a chromium-nickel alloy and / or an aluminum alloy.
Das bevorzugt verwendete Molybdänkarbid ist ein Karbid der Zusammensetzung M02C, und die bevorzugt eingesetzten niedrig schmelzenden Legierungen sind Nickelchromlegierungen mit 75 bis 85% Nickel und 15 bis 25% Chrom oder Aluminiumlegierungen mit 10 bis 20% Silizium und 80 bis 90% Aluminium.The preferred molybdenum carbide is a carbide with the composition M 02 C, and the preferred low-melting alloys are nickel-chromium alloys with 75 to 85% nickel and 15 to 25% chromium or aluminum alloys with 10 to 20% silicon and 80 to 90% aluminum.
Das Spritzpulver kann in der Form von Mischungen der drei Komponenten verwendet werden, bevorzugt enthält das Spritzpulver aber Mikropellets und/oder Verbundpulver aus mindestens zwei der Komponenten, und die Pulver werden bevorzugt durch ein Plasmaspritzverfahren aufgetragen.The wettable powder can be used in the form of mixtures of the three components, but preferably the wettable powder contains micropellets and / or composite powder from at least two of the components, and the powders are preferably applied by a plasma spraying process.
Bei mit den erfindungsgemässen Spritzpulvern beschichteten Ringen in sowohl überspritzter als auch in ein- oder beidseitig gekammerter Form wurde in Motortestläufen gefunden, dass bei einem Molybdängehalt im Pulver von weniger als 20 Gewichtsprozent der Verschleiss an der Lauffläche des Gegenpartners derZylinderlaufbüchse zu gross wird, bei Gehalten von mehr als 60 Gewichtsprozent ist dagegen die Verschleissfestigkeit der Spritzschicht nicht ausreichend. Umgekehrt ist entsprechend bei einem Molybdänkarbidanteil von unter 25 Gewichtsprozent die Eigenverschleissfestigkeit der Schichten zu gering, während grössere Molybdänkarbidanteile von über 50 Gewichtsprozent den Verschleiss der Reibpartner unzulässig heraufsetzt.In the case of rings coated with the wettable powders according to the invention in both overmolded and chambered form on one or both sides, it was found in engine test runs that with a molybdenum content in the powder of less than 20 percent by weight, the wear on the running surface of the counterpart of the cylinder liner becomes too great, with contents of on the other hand, the wear resistance of the spray coating is not sufficient by more than 60 percent by weight. Conversely, with a molybdenum carbide content of less than 25 percent by weight, the inherent wear resistance of the layers is too low, while larger molybdenum carbide content of over 50 percent by weight increases the wear of the friction partners inadmissibly.
Überraschenderweise wurde aber auch gefunden, dass Schichten mit Molybdän und Molybdänkarbid innerhalb der angegebenen Mengenverhältnisse keinerlei Einfluss auf die Brandspurfestigkeit der Schichten besitzen. Die Schichten mit Molybdän und Molybdänkarbid waren ähnlich brandspursicher wie reine Molybdänschichten.Surprisingly, it was also found that layers with molybdenum and molybdenum carbide have no influence on the fire resistance of the layers within the stated proportions. The layers with molybdenum and molybdenum carbide were similarly fire-proof as pure molybdenum layers.
Die Zugabe der niedrigschmelzenden Legierungen auf der Basis von Chromlegierungen, Chromnickellegierungen und/oder Aluminiumlegierungen erhöht die Zähigkeit der Schichten, so dass die so hergestellten Kolbenringe höhere Schichtausbruchssicherheit aufweisen. So konnten in Versuchen die Laufflächen von Kolbenringen mit derartigen Pulverbeschichtungen in überspritzter Form mit nahezu scharfen Kanten, d.h. deren Kanten nicht wie bisher üblich abgewinkelt waren, sondern deren Kanten fast rechtwinklig zur Lauffläche verliefen, hergestellt werden. Derartige Ringe zeigten in den Motortestläufen im allgemeinen keinerlei Schichtbeschädigungen im Kantenbereich.The addition of the low-melting alloys based on chromium alloys, chromium-nickel alloys and / or aluminum alloys increases the toughness of the layers that the piston rings produced in this way have higher layer breakout security. In trials, the running surfaces of piston rings with such powder coatings could be produced in overmolded form with almost sharp edges, ie their edges were not angled as previously, but their edges were almost perpendicular to the running surface. In the engine test runs, such rings generally showed no layer damage in the edge region.
Wenn auch die erfindungsgemässen Spritzpulver bevorzugt zur Beschichtung von Kolbenringen eingesetzt werden sollen, so können sie jedoch auch im Sinne der Erfindung für ähnliche Anwendungsfälle eingesetzt werden. Gefunden wurde, dass das Pulver sich auch zur Beschichtung von Feuerstegen und Kolbenböden der Kolben in Verbrennungskraftmaschinen eignet, und ebenso wurden die Reibflächen von Synchronringen mit den erfindungsgemässen Pulvern beschichtet.If the wettable powders according to the invention are also to be used preferably for coating piston rings, they can also be used for similar applications in the sense of the invention. It was found that the powder is also suitable for coating the top land and piston crowns of the pistons in internal combustion engines, and the friction surfaces of synchronizer rings were also coated with the powders according to the invention.
