Verfahren zur Beschichtung von MetalloberflächenProcess for coating metal surfaces

Anwendungsgebietfield of use

Die Erfindung betrifft ein Verfahren zur Beschichtung von Metalloberflächen mittels Plasmaspritzen zur Verbesserung der Eigenschaften der Metalloberfläche·The invention relates to a method for coating metal surfaces by means of plasma spraying in order to improve the properties of the metal surface.

Charakteristik der bekannten technischen LösungenCharacteristic of the known technical solutions

Es ist bekannt, pulverisierte Metalle,' Metalloxyde usw. mittels Plasmaspritzen auf Metalloberflächen aufzubringen. Die Eigenschaften dieser Metalloberflächen werden dabei verbessert z. B. widerstandsfähig gegenüber Korrosion gemacht. ' Die Anwendungsbreite des Plasmaspritzens umfaßt bisher die Gebiete Korrosionsschutz, Oberflächenveredlung und Strukturierung, Die Anwendungsbreite des Plasmaspritzens ist gering und decktIt is known to apply powdered metals, metal oxides, etc. by means of plasma spraying on metal surfaces. The properties of these metal surfaces are thereby improved z. B. made resistant to corrosion. 'The scope of application of plasma spraying so far covers the fields of corrosion protection, surface finishing and structuring, the scope of application of plasma spraying is low and covers

nur bestimmte Gebiete ab, Ziel der Erfindungonly certain areas from, aim of the invention

Ziel der Erfindung ist die Verbreitung des Anwendungsgebietes des Plasmaspritzens.The aim of the invention is the spread of the field of application of plasma spraying.

Aufgabe der Erfindung . . .Object of the invention. , ,

Aufgabe der Erfindung ist die Nutzbarmachung des Plasmaspritzens für das Gebiet der Schmierungstechnik.The object of the invention is the utilization of plasma spraying for the field of lubrication technology.

Wesen der ErfindungEssence of the invention

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß erstmalig pulverisiertes Molybdänsulfid oder eine Mischung aus Molybdän und Schwefel mit einem Plasmaspritzgerät und einem Spritzgang oder die Einzelkomponente Molybdän mit einem Plasmaspritzgerät auf Gleitflächen aufgebracht wird, wobei in die Plasmaflamme mittels Trogergas Schwefel geleitet wird.According to the invention the object is achieved in that powdered molybdenum sulfide or a mixture of molybdenum and sulfur for the first time with a plasma spray gun and a spray pass or the single component molybdenum is applied with a plasma spray gun on sliding surfaces, wherein in the plasma flame by means of tenter gas sulfur is passed.

Ausführungsbeispielembodiment

Nachfolgend wird die Erfindung an einem Ausführungsbeispiel näher beschrieben.The invention will be described in more detail with reference to an exemplary embodiment.

Zur Erreichung von Schmiereigenschaften von gleitenden Flächen wie Zapfen, Gleitlager und führungen wird erstmalig Molybdändisulf id im Plasmaspritzverfaliren auf Gleitflächen aufgebracht.To achieve lubricating properties of sliding surfaces such as pins, plain bearings and guides Molybdändisulf id is applied for the first time in the plasma spray Verfaliren on sliding surfaces.

213790213790

Die aus Molybdändisulfid bestehende Schmierschiclit liegt somit im festen Aggregatzustand vor und ist .zugleich Lagerfläche. Es ist auch möglich, die Elemente Molybdän und Schwefel zu mischen und dieses Gemisch auf die gleitenden Flächen mittels des Plasmaspritzens aufzubringen.The existing of molybdenum disulfide Schmierschiclit is thus present in the solid state and is .zugleich storage area. It is also possible to mix the elements molybdenum and sulfur and apply this mixture to the sliding surfaces by means of plasma spraying.

Weiterhin ist es möglich, Molybdän mit einer Plasmaspritzeinrichtung auf die gleitenden "Flächen aufzubringen und in die " Plasmaflamme Schwefel einzuleiten. Auf der gleitenden Fläche entsteht in bestimmten Maße wieder Molybdändisulfid.Furthermore, it is possible to apply molybdenum with a plasma spraying device to the sliding "surfaces and to introduce sulfur into the plasma flame. On the sliding surface molybdenum disulfide is formed to a certain extent again.
