Description
Die vorliegende Erfindung betrifft ein Verfahren zum Herstellen eines Gussbauteils mit einer Beschichtung, ein Werkstück, eine Verwendung eines Wandabschnitts eines Bauteils als Abschirmelement beim Beschichten sowie ein Werkzeug.The present invention relates to a method for producing a cast component with a coating, a workpiece, a use of a wall section of a component as a shielding element during coating, and a tool.
Aus dem Stand der Technik ist es bekannt, Bauteile zu beschichten, um etwa Oberflächeneigenschaften, wie eine Verschleißbeständigkeit, zu verbessern. Die
Es ist daher eine Aufgabe der vorliegenden Erfindung, ein Verfahren zum Herstellen eines Gussbauteils, ein Werkstück, eine Verwendung eines Wandabschnitts eines Bauteils sowie ein Werkzeug anzugeben, welche die vorgenannten Nachteile beseitigen und zu einer Kostenreduktion in der Herstellung beitragen.It is therefore an object of the present invention to provide a method for producing a cast component, a workpiece, a use of a wall section of a component and a tool which eliminate the aforementioned disadvantages and contribute to a cost reduction in production.
Diese Aufgabe wird durch ein Verfahren gemäß Anspruch 1, durch ein Werkstück gemäß Anspruch 10, durch eine Verwendung gemäß Anspruch 11 sowie durch ein Werkzeug gemäß Anspruch 12 gelöst. Weitere Vorteile und Merkmale ergeben sich aus den Unteransprüchen, der Beschreibung sowie den beigefügten Figuren.This object is achieved by a method according to claim 1, by a workpiece according to
Erfindungsgemäß umfasst ein Verfahren zum Herstellen eines Bauteils mit einer Beschichtung die Schritte:
- - Formen eines Bauteils mit zumindest einem Abschirmelement, wobei das zumindest eine Abschirmelement ausgelegt ist, zumindest einen Bereich des Bauteils bei einem Beschichten oder bei einem Beschichtungsprozess abzuschirmen;
- - Aufbringen, insbesondere Aufsprühen, einer Beschichtung auf zumindest einen Beschichtungsbereich des Bauteils, wobei das zumindest eine Abschirmelement bereichsweise eine Beschichtung des Bauteils verhindert oder zumindest derart minimiert, dass zweckmäßigerweise keine weiteren Bearbeitungsschritte zum Entfernen von unerwünscht aufgetragenem Beschichtungswerkstoff nötig sind.
- Forming a component with at least one shielding element, wherein the at least one shielding element is designed to shield at least one region of the component during a coating or during a coating process;
- Application, in particular spraying, of a coating on at least one coating area of the component, the at least one shielding element preventing or at least minimizing coating of the component in areas such that expediently no further processing steps are necessary to remove undesirably applied coating material.
Das Formen ist bevorzugt als ein Urformen zu verstehen, insbesondere bevorzugt als ein Gießverfahren, wobei als Gieß- oder Gusswerkstoffe sowohl metallische Werkstoffe als auch nicht metallische Werkstoffe verwendet werden können. Der große Vorteil besteht vorliegend darin, dass beim Formen des Bauteils integral ein Abschirmelement, oder mehrere, mitgeformt wird, welches ausgelegt und orientiert ist, dass bei einem späteren Beschichtungsvorgang des Bauteils zumindest ein Bereich des Bauteils nicht, oder nur wenig, mit dem Beschichtungswerkstoff in Kontakt kommt. Insbesondere wenn die Beschichtung durch ein Sprühverfahren, wie ein thermisches Sprühverfahren, realisiert wird, kann damit eine sehr effektive Abschirmung realisiert werden. Gemäß einer Ausführungsform bestimmt das Beschichtungsverfahren Form und/oder Lage des Abschirmelements. Kommt als Beschichtungsverfahren beispielsweise ein Spritzverfahren, wie ein thermisches Spritzverfahren, zum Einsatz, steht das Abschirmelement zweckmäßigerweise zumindest abschnittsweise senkrecht zu einem Beschichtungsstrahl bzw. folgt der (Bahn-)Bewegung des Beschichtungsstrahls. Damit kann eine Abschirmwirkung erzielt werden, welche insbesondere einen hinter dem Abschirmelement liegenden Bereich, bezogen auf die Beschichtungsrichtung, abschirmt oder schützt.The molding is preferably to be understood as a primary molding, particularly preferably as a casting process, it being possible to use both metallic materials and non-metallic materials as casting or casting materials. The great advantage here is that when the component is formed, one or more shielding elements are also formed integrally, which are designed and oriented so that during a later coating process of the component at least one area of the component does not, or only slightly, with the coating material Contact comes. In particular, if the coating is implemented using a spraying process, such as a thermal spraying process, very effective shielding can thus be implemented. According to one embodiment, the coating method determines the shape and / or position of the shielding element. If, for example, a spraying process, such as a thermal spraying process, is used as the coating process, the shielding element is expediently at least partially perpendicular to a coating beam or follows the (path) movement of the coating beam. A shielding effect can thus be achieved which, in particular, shields or protects an area located behind the shielding element in relation to the coating direction.
Gemäß einer bevorzugten Ausführungsform umfasst das Verfahren den Schritt:
- - Gießen des Bauteils im Schwerkraftguss oder im Kokillenguss, insbesondere im Schwerkraft-Kokillenguss.
- - Casting the component in gravity casting or in permanent mold casting, in particular in gravity permanent mold casting.
Gemäß einer Ausführungsform umfasst das Verfahren den Schritt:
- - Entfernen, insbesondere mechanisches Entfernen, des Abschirmelements nach dem Beschichten.
- - Removal, in particular mechanical removal, of the shielding element after coating.
Gemäß einer Ausführungsform umfasst das Verfahren den Schritt:
- - Nachbearbeiten des Beschichtungsbereichs.
- - Post processing of the coating area.
Gemäß einer bevorzugten Ausführungsform umfasst das Verfahren den Schritt:
- - Beschichten mittels Kaltgasspritzen.
- - Coating by means of cold gas spraying.
Zweckmäßigerweise ist das oder das zumindest eine Abschirmelement neben oder im Bereich bzw. angrenzend an den jeweiligen Beschichtungsbereich angeordnet. Etwaiger auftretender Sprühnebel oder Overspray kann damit sehr gut auf den Beschichtungsbereich begrenzt werden.The or the at least one shielding element is expediently arranged next to or in the area or adjacent to the respective coating area. Any spray mist or overspray that may occur can thus be very effectively limited to the coating area.
Wie bereits erwähnt, orientieren sich Form und/oder Lage zweckmäßigerweise am Beschichtungsverfahren, insbesondere beispielsweise am Verfahrweg eines Sprühkopfes der Beschichtungseinrichtung. Zweckmäßigerweise steht das Abschirmelement zumindest bereichsweise senkrecht oder im Wesentlichen senkrecht zu einem Beschichtungsstrahl.As already mentioned, the shape and / or position are expediently based on the coating process, in particular, for example, on the travel path of a spray head of the coating device. The shielding element is expediently at least partially perpendicular or essentially perpendicular to a coating beam.
Gemäß einer Ausführungsform umfasst das Verfahren den Schritt:
- - Formen des Abschirmelements durch eine zumindest bereichsweise beabstandete Anordnung von zumindest zwei Formelementen einer Guss- oder Gießform, wodurch ein Formhohlraum gebildet ist.
- Shaping of the shielding element by an arrangement of at least two shaped elements of a casting or casting mold that is at least regionally spaced apart, whereby a mold cavity is formed.
Gemäß einer Ausführungsform ist das Abschirmelement ausgelegt und/oder orientiert, einen Hohlraum oder Kanal des jeweiligen Bauteils abzuschirmen oder zumindest bereichsweise zu verschießen, wie, gemäß einer Ausführungsform, beispielsweise einen Ein- oder Auslasskanal eines Zylinderkopfes eines Verbrennungsmotors. Bevorzugt weist das Abschirmelement hierzu eine kreisförmige oder kreisringförmige Form auf. Zweckmäßigerweise formen die beiden vorgenannten Formelemente, insbesondere Kerne, den in der Rede stehenden Kanal. Gemäß einer Ausführungsform ist ein Abstand der beiden Kerne zueinander so gewählt, dass der entstehende Formhohlraum durch die Schmelze nicht vollständig gefüllt wird. Zweckmäßigerweise kann so ein kreisringförmiges Abschirmelement geformt werden, welches beispielsweise mittig oder in etwa mittig eine Öffnung frei lässt. Alternativ können sich die Kerne, beispielsweise mittig, auch berühren, insbesondere aneinander anliegen. Dadurch entsteht, je nach Ausgestaltung der Kerne, ebenfalls ein beispielsweise kreisringförmiges Abschirmelement. Der Abstand zwischen den Kernen kann auch so gewählt werden, dass der Formhohlraum durch die Schmelze vollständig gefüllt wird. Beim Abguss entsteht so ein Abschirmelement, welches die jeweilige Öffnung oder einen Kanal vollständig verschließt.According to one embodiment, the shielding element is designed and / or oriented to screen a cavity or channel of the respective component or to close it at least in areas, such as, according to one embodiment, for example an inlet or outlet channel of a cylinder head of an internal combustion engine. For this purpose, the shielding element preferably has a circular or annular shape. The two aforementioned shaped elements, in particular cores, expediently form the channel in question. According to one embodiment, a distance between the two cores is selected so that the resulting mold cavity is not completely filled by the melt. An annular shielding element can expediently be formed in this way, which for example leaves an opening free in the middle or approximately in the middle. Alternatively, the cores can also touch one another, for example in the middle, in particular bear against one another. As a result, depending on the configuration of the cores, a shielding element, for example a circular ring, is also created. The distance between the cores can also be chosen so that the mold cavity is completely filled by the melt. During the casting process, a shielding element is created that completely closes the respective opening or a channel.
Bevorzugt ist der der Beschichtungsbereich ein Ventilsitz eines Zylinderkopfs eines Verbrennungsmotors. Hierbei kann es sich sowohl um den Einlass- als auch um den Auslassventilsitz handeln. Die kreisringförmige Geometrie eines Ventilsitzes bzw. der sich daran anschließende Ein- oder Auslasskanal des Zylinderkopfes legt die Verwendung eines kreisringförmigen Abschirmelements nahe. Das Abschirmelement bzw. die Abschirmelemente können aber jede beliebige Form aufweisen, welche geeignet ist, eine bauteilspezifische Abschirmwirkung zu erzielen.The coating area is preferably a valve seat of a cylinder head of an internal combustion engine. This can be both the inlet and the outlet valve seat. The circular geometry of a valve seat or the adjoining inlet or outlet channel of the cylinder head defines the use an annular shielding element close. The shielding element or the shielding elements can, however, have any shape that is suitable for achieving a component-specific shielding effect.
Weiter richtet sich die Erfindung auf ein Werkstück, insbesondere einen Zylinderkopf einer Verbrennungskraftmaschine, welcher nach dem erfindungsgemäßen Verfahren hergestellt wurde.The invention is also directed to a workpiece, in particular a cylinder head of an internal combustion engine, which was manufactured using the method according to the invention.
Die Erfindung richtet sich auch auf eine Verwendung eines Wandabschnitts eines Bauteils, insbesondere eines gegossenen Bauteils, als Abschirmelement beim Beschichten eines Bauteils, wobei der Wandabschnitt integral mit dem Bauteil geformt und nach einem Beschichten des Bauteils entfernt wird.The invention is also directed to the use of a wall section of a component, in particular a cast component, as a shielding element when coating a component, the wall section being formed integrally with the component and removed after the component has been coated.
Weiter richtet sich die Erfindung auf ein Werkzeug für ein erfindungsgemäßes Verfahren. Insbesondere umfasst das Werkzeug eine Form zum Formen, insbesondere Urformen, des Bauteils. Bevorzugte Werkzeuge sind insbesondere Gießwerkzeuge bzw. Gießformen oder Pressen.The invention is also directed to a tool for a method according to the invention. In particular, the tool comprises a mold for shaping, in particular primary shaping, of the component. Preferred tools are in particular casting tools or casting molds or presses.
Weitere Vorteile und Merkmale ergeben sich aus der nachfolgenden Beschreibung eines Verfahrens bzw. einer Verwendung eines Abschirmelements bzw. eines Werkzeugs mit Bezug auf die beigefügten Figuren.Further advantages and features emerge from the following description of a method or a use of a shielding element or a tool with reference to the attached figures.
