Abstract
Description
Die Erfindung betrifft einen drahtförmigen Spritzwerkstoff, insbesondere zum Lichtbogendrahtspritzen, umfassend im Wesentlichen Eisen. Die Erfindung betrifft weiter ein Verfahren zum Beschichten eines Substrats, bei dem ein drahtförmiger Spritzwerkstoff in einem Lichtbogen aufgeschmolzen und als Schicht auf dem Substrat abgeschieden wird.The Invention relates to a wire-shaped spray material, in particular for arc wire spraying, comprising substantially Iron. The invention further relates to a method for coating a substrate in which a wire-shaped spray material in a Arc melted and deposited as a layer on the substrate becomes.
Bei der Herstellung von Verbrennungsmotoren wird aus Gründen der Energieeffizienz und der Emissionsreduzierung eine möglichst geringe Reibung und eine hohe Abrieb- und Verschleißfestigkeit angestrebt. Hierzu werden Motorbauteile, wie zum Beispiel Zylinderbohrungen bzw. deren Wandungen mit einer Laufflächenschicht versehen oder es werden Laufbuchsen in die Zylinderbohrungen eingesetzt, welche mit einer Laufflächenschicht versehen werden. Das Aufbringen solcher Laufflächenschichten erfolgt zumeist mittels thermischen Spritzens, beispielsweise Lichtbogendrahtspritzen. Beim Lichtbogendrahtspritzen wird zwischen zwei drahtförmigen Spritzwerkstoffen ein Lichtbogen durch Anlegen einer Spannung erzeugt. Dabei schmelzen die Drahtspitzen ab und werden beispielsweise mittels eines Zerstäubergases auf die zu beschichtende Oberfläche, beispielsweise die Zylinderwand, befördert, wo sie sich anlagern.at The manufacture of internal combustion engines is for the sake of Energy efficiency and emission reduction as possible low friction and high abrasion and wear resistance. For this purpose, engine components, such as cylinder bores or their walls provided with a tread layer or it Bushes are inserted into the cylinder bores, which with a tread layer be provided. The application of such tread layers is usually by thermal spraying, for example electric arc wire spraying. When wire arc spraying is between two wire-shaped spray materials generates an arc by applying a voltage. It will melt the wire tips and are for example by means of a nebulizer gas on the surface to be coated, For example, the cylinder wall, transported where they attach.

Die Aufgabe wird erfindungsgemäß gelöst durch einen drahtförmigen Spritzwerkstoff mit den Merkmalen des Anspruchs 1.The The object is achieved by a wire-shaped Spray material with the features of claim 1.

Ein erfindungsgemäßer drahtförmiger Spritzwerkstoff, insbesondere zum Lichtbogendrahtspritzen, umfasst im Wesentlichen Eisen. Der Spritzwerkstoff ist zumindest mit Kohlenstoff als Mikrolegierung derart gebildet, dass bereits beim Erstarren des Spritzwerkstoffs Martensit und Bainit entstehen. Mikrolegierungen sind solche Legierungen, die überwiegend aus einem Bestandteil gebildet sind, dem im Verhältnis zu einer Gesamtmasse nur geringe Mengen weiterer Bestandteile zugegeben sind. Perlit ist eine Mischphase aus weichen ferritischen und harten karbidischen Anteilen bei kohlenstoffhaltigen Stählen. Martensit ist ein hartes, verschleißfestes Gefüge. Die Bildung von Perlit und Martensit kann durch die Art der Abkühlung des Spritzwerkstoffs und durch die Wahl der Legierungsbestandteile der Mikrolegierung beeinflusst werden. Bei einer Anlagerung einer mittels Lichtbogendrahtspritzen unter Nutzung des erfindungsgemäßen Spritzwerkstoffs erzeugten Schicht auf einem Substrat, beispielsweise einer Zylinderlauffläche, bildet sich z. B. eine weiche, duktile Matrix aus Perlit (insbesondere feinperlitisch) mit harten, verschleißfesten Inseln aus Martensit sowie vorzugsweise Chromkarbiden. Die Schicht ist besonders reibungsarm, verschleißbeständig und korrosionsbeständig. Die Verschleißbeständigkeit wird insbesondere durch sich in der Schicht bildende Chromkarbide bewirkt. Auf diese Weise kann die Reibung, insbesondere die Festkörperreibung zwischen der Schicht und einem Reibpartner, beispielsweise Kolbenringen erheblich reduziert werden. Bei der Wahl der Legierungselemente wird gezielt darauf geachtet, dass vorwiegend Phasen mit niedrigen Adhäsionskoeffizienten entstehen.One wire-shaped spray material according to the invention, in particular for arc wire spraying, essentially comprises Iron. The spray material is such at least with carbon as a micro-alloy formed that already during solidification of the spray martensite and bainite arise. Microalloys are such alloys, the predominantly are formed of one component, in proportion to a total mass only small amounts of other ingredients are added. perlite is a mixed phase of soft ferritic and hard carbidic Shares in carbon steels. Martensite is a hard, wear resistant Structure. The Formation of perlite and martensite may be due to the nature of the cooling of the Spray material and by the choice of the alloy components of the Microalloying be influenced. In an addition of a means of Arc wire spraying using the spray material according to the invention produced layer on a substrate, such as a cylinder surface, forms z. B. a soft, ductile matrix of perlite (in particular fine-pearlitic) with hard, wear-resistant martensite islands and preferably chromium carbides. The layer is particularly low-friction, wear resistant and corrosion resistant. The wear resistance is especially due to chromium carbides forming in the layer causes. In this way, the friction, in particular the solid friction between the layer and a friction partner, such as piston rings considerably be reduced. In the choice of alloying elements is targeted ensured that predominantly phases with low adhesion coefficients arise.
