Abstract

The inner surface of the hollow body is machined in a single operation without lubricants by means of a tool with defined and/or non defined surface profile.

Description

Die vorliegende Erfindung betrifft ein Verfahren zur Oberflächenbearbeitung der Innenseite von Hohlkörpern, insbesondere von Zylinderbohrungen, als Vorbereitung zum Aufbringen einer thermisch gespritzten Schicht, wobei ein Teil des die Innenseite bildenden Materials abgetragen und eine Oberfläche mit einer definierten Struktur und/oder Güte erzeugt wird.The present invention relates to a method for surface processing the inside of hollow bodies, especially cylinder bores, in preparation for applying a thermal sprayed layer, part of which forms the inside Material removed and a surface with a defined Structure and / or quality is generated.

Ein gattungsgemäßes Verfahren ist aus der EP 0 716 158 A1 bekannt. Dort wird ein Verfahren zur Herstellung von Motorblöcken mit beschichteten Zylinderbohrungen beschrieben, bei dem der Motorblock zunächst aus einem Metall gegossen wird und anschließend Schmutzreste von den Wandungen der gegossenen Zylinderbohrungen entfernt werden, so daß zumindest eine ringförmige gereinigte frische Metalloberfläche bereitgestellt wird. Anschließend wird eine plasmagespritzte Schicht auf dieser so vorbereiteten Oberfläche abgelagert und diese nachgearbeitet.A generic method is known from EP 0 716 158 A1. There is a process for manufacturing engine blocks described with coated cylinder bores, in which the engine block is first cast from a metal and then Debris from the walls of the cast cylinder bores be removed so that at least one annular cleaned fresh metal surface is provided. Then will a plasma sprayed layer on this prepared surface deposited and reworked.

Die Vorbereitung der Zylinderbohrungen geschieht üblicherweise durch Bearbeiten mit Korundstrahlen und anschließende Entfettung. Ziel ist es, eine fettfreie Oberfläche mit einem Rz-Wert von etwa 25 bis 65 µm zu erhalten. Problematisch dabei ist, daß die Zylinderbohrungen durch die Vorbereitung lagegenau dargestellt werden müssen, da nach dem Gießen die Position der gegossenen Zylinderbohrung beträchtlich von dem vorgeschriebenen Wert abweichen kann. Bei der Herstellung von Motorblöcken aus untereutektischem Aluminium im Druckgußverfahren ergibt sich das weitere Problem, daß durch den Gießprozeß vor allem im unteren Bereich der Zylinderbohrungen Inhomogenitäten entstehen können. Es können sich Lunker oder Poren im Werkstoff bilden, bedingt durch einen Schrumpfungsprozeß während des Gießens (sogenannte Schrumpflunker). Bei der Oberflächenbearbeitung und Aufrauhung werden diese Poren oder Lunker freigelegt und teilweise noch vergrößert. Dadurch bleiben Strahlgutrückstände und Lösemittel - bzw. Schmiergutrückstände - in den offenen Lunkern zurück, die zu einer schlechten Haftung der anschließend aufgebrachten tribologischen Schicht führen. Da die Beschichtung nämlich bei hohen Temperaturen stattfindet, dehnt sich das in den offenen Lunkern verbliebene Lösemittel aus, sodaß sich Beulen und Abplatzungen bilden können und insgesamt eine schlechte Anbindung der tribologischen Schicht an die Wandung resultiert.The cylinder bores are usually prepared by machining with corundum blasting and subsequent degreasing. The goal is to obtain a grease-free surface with an R z value of approximately 25 to 65 µm. The problem here is that the cylinder bores have to be represented in the correct position by the preparation, since after casting the position of the cast cylinder bore can deviate considerably from the prescribed value. In the manufacture of engine blocks from hypoeutectic aluminum using the die-casting process, there is the further problem that the casting process can cause inhomogeneities, especially in the lower region of the cylinder bores. Voids or pores can form in the material due to a shrinking process during casting (so-called shrinking voids). During surface processing and roughening, these pores or voids are exposed and partially enlarged. As a result, blasting material residues and solvents - or lubricating material residues - remain in the open cavities, which lead to poor adhesion of the tribological layer subsequently applied. Since the coating takes place at high temperatures, the solvent remaining in the open cavities expands, so that dents and flaking can form, and overall a poor connection of the tribological layer to the wall results.

Aufgabe der vorliegenden Erfindung ist es daher, ein Verfahren der oben genannten Art bereitzustellen, das auf möglichst einfache Weise fettfreie Oberflächen einer bestimmten Oberflächengüte bereitstellt, auf welche die thermisch gespritzten Schichten einfach und gut haftend aufzubringen sind.The object of the present invention is therefore a method to provide the above type, the simplest possible Such as grease-free surfaces of a certain surface quality provides on which the thermally sprayed layers simply and are easy to apply.

Die Lösung besteht darin, daß die Innenseite in einem Verfahrensschritt ohne Schmierstoff trocken zerspant wird, wobei Werkzeug mit einem definierten und/oder undefinierten Oberflächenprofil verwendet wird.The solution is that the inside in one process step is machined dry without lubricant using tool with a defined and / or undefined surface profile is used.

Unter "trocken zerspanen" wird dabei verstanden, daß keine Schmierung vorgenommen wird oder daß höchstens eine Minimalschmierung in einem Volumenstrom von weniger als 150 ml/h, bei der die Späne bzw. die Oberfläche als trocken deklariert werden, vorgenommen wird. "Dry machining" is understood to mean that none Lubrication is carried out or that at most minimal lubrication in a volume flow of less than 150 ml / h, at the chips or surface are declared dry, is made.

Erfindungsgemäß ist also vorgesehen, die Bohrungen trocken zu bearbeiten, z. Bsp. durch Ausspindeln, Bürsten, Rändeln, Zirkularfräsen oder Kombinationen aus einem oder mehreren dieser Verfahren.According to the invention, it is therefore provided to process the bores dry, e.g. For example, by spindling, brushing, knurling, circular milling or combinations of one or more of these methods.

Das Werkzeug kann ein definiertes Oberflächenprofil aufweisen, so daß durch die Bearbeitung einer Oberfläche mit einer definierten Struktur resultiert. Das nachträgliche Entfetten bzw. Reinigen und Aufrauhen entfällt. Nach der Oberflächenbearbeitung kann sofort eine Schicht durch thermisches Spritzen aufgetragen werden.The tool can have a defined surface profile, so that by machining a surface with a defined one Structure results. Subsequent degreasing or cleaning and roughening is eliminated. After finishing the surface can immediately a layer can be applied by thermal spraying.
