Description

Die Erfindung betrifft ein Verfahren zur Innenbeschich­ tung von Zylinderlaufflächen, insbesondere Aluminium-Lauf­ flächen.The invention relates to a method for internal coating device of cylinder running surfaces, in particular aluminum barrel surfaces.

Um das Fahrzeuggewicht und damit den Kraftstoffverbrauch zu senken, werden Aluminium-Motorblöcke eingesetzt. Die Zy­ linder-Laufflächen aus Aluminiumguß sind allerdings nicht mit ausreichender Verschleißbeständigkeit herstellbar, so daß Gußeiseneinsätze angewendet werden oder eine chemische Ober­ flächenbehandlung durchgeführt werden muß. Durch die Veröf­ fentlichung "Rotaplasma Applications in the Automotive Indu­ stry" von G. Barbezat, S. Keller und K.H. Wegner, Proceedings of ITSC, Mai 1995, Seite 9 ff. ist ein Verfahren zur Ober­ flächenbeschichtung durch thermisches Spritzen mittels Rota­ tionsplasmabrennen bekannt.About the vehicle weight and thus the fuel consumption to lower, aluminum engine blocks are used. The Zy Linder treads made of cast aluminum are not included sufficient wear resistance can be produced so that Cast iron inserts are used or a chemical upper surface treatment must be carried out. By the publisher publication "Rotaplasma Applications in the Automotive Indu stry "by G. Barbezat, S. Keller and K.H. Wegner, Proceedings of ITSC, May 1995, page 9 ff. is a procedure for the super surface coating by thermal spraying using Rota tion plasma burn known.

Sämtliche bekannte Verfahren liefern noch keine befrie­ digenden Ergebnisse.All known methods do not yet provide any exempt results.

Die Aufgabe der vorliegenden Erfindung besteht deshalb darin, ein neuartiges Verfahren zur verschleißfesten Innen­ beschichtung von Zylinder-Laufflächen, insbesondere von Alu­ minium-Laufflächen anzugeben.The object of the present invention is therefore therein, a novel method of wear-resistant interior coating of cylinder treads, especially aluminum minium treads.

Diese Aufgabe wird dadurch gelöst, daß in die Zylinder-Lauf­ fläche pulverförmige Zusatzwerkstoffe mittels Laserstrah­ lung legiert werden.This object is achieved in that in the cylinder barrel surface of powdery filler materials using a laser beam be alloyed.

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

Als Zusatzstoffe werden Metall- oder Metallkeramik-Mi­ schungen verwendet.Metal or metal-ceramic Mi uses schungen.

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.
