Abstract

Bearing surfaces of cylinders made of aluminium are coated by a process in which a laser beam is used to form an alloy with powder additives. Preferably a thin layer of the bearing surface is melted and the powdered material is added. Preferred additives are metal or metal - ceramic mixtures. Improves wear resistance of lightweight cylinders.

Description

Die Erfindung betrifft ein Verfahren zur Innenbeschichtung von Zylinderlaufflächen, insbesondere Aluminium-Laufflächen.The invention relates to a method for internal coating of cylinder treads, especially aluminum treads.

Um das Fahrzeuggewicht und damit den Kraftstoffverbrauch zu senken, werden Aluminium-Motorblöcke eingesetzt. Die Zylinder-Laufflächen aus Aluminiumguß sind allerdings nicht mit ausreichender Verschleißbeständigkeit herstellbar, so daß Gußeiseneinsätze angewendet werden oder eine chemische Oberflächenbehandlung durchgeführt werden muß. Durch die Veröffentlichung "Rotaplasma Applications in the Automotive Industry" von G. Barbezat, S. Keller und K.H. Wegner, Proceedings of ITSC, Mai 1995, Seite 9 ff. ist ein Verfahren zur Oberflächenbeschichtung durch thermisches Spritzen mittels Rotationsplasmabrennen bekannt.About the vehicle weight and thus the fuel consumption to lower, aluminum engine blocks are used. The cylinder treads cast aluminum are not included sufficient wear resistance can be produced so that Cast iron inserts are applied or a chemical surface treatment must be carried out. Through the publication "Rotaplasma Applications in the Automotive Industry" by G. Barbezat, S. Keller and K.H. Wegner, Proceedings of ITSC, May 1995, page 9 ff. is a process for surface coating by thermal spraying using rotary plasma burning known.

Sämtliche bekannte Verfahren liefern noch keine befriedigenden Ergebnisse.All known methods do not yet provide satisfactory Results.

Die Aufgabe der vorliegenden Erfindung besteht deshalb darin, ein neuartiges Verfahren zur verschleißfesten Innenbeschichtung von Zylinder-Laufflächen, insbesondere von Aluminium-Laufflächen anzugeben.The object of the present invention is therefore a new method for wear-resistant interior coating of cylinder treads, especially aluminum treads specify.

Diese Aufgabe wird dadurch gelöst, daß in die Zylinder-Lauffläche pulverförmige Zusatzwerkstoffe mittels Laserstrahlung legiert werden.This object is achieved in that in the cylinder tread powdered filler materials using laser radiation be alloyed.

Das neuartige Verfahren besteht insbesondere darin, daß eine dünne Schicht der Lauffläche mittels Laserstrahlung aufgeschmolzen wird und in das Schmelzbad pulverförmige Zusatzstoffe gegeben werden. Nach Aushärtung entsteht eine homogene verschleißfeste Lauffläche.The novel method consists in particular in that a thin layer of the tread is melted using laser radiation and powder additives in the weld pool are given. After curing, a homogeneous is created wear-resistant tread.

Als Zusatzstoffe werden Metall- oder Metallkeramik-Mischungen verwendet.Metal or metal-ceramic mixtures are used as additives used.

Die Oberflächen der zu behandelnden Zylinder-Laufflächen sollten möglichst frei von Gaseinschlüssen oder anderweitigen Einschlüssen sein.The surfaces of the cylinder surfaces to be treated should be as free from gas inclusions or otherwise Inclusions.
