Definitions
- Anodizing converts the surface of an aluminum alloy substrate into an aluminum oxide layer.
- Components made of anodized aluminum accordingly have an oxide layer on the surface. Oxide-free surface areas can be realized only by masking or a subsequent removal of the oxide layer due to the dipping process. By laser processing, the oxide layer of a component made of anodized aluminum, for example, be removed locally.
- an aluminum alloy having a silicon content of e.g. 12%. Since the solubility of silicon in an aluminum alloy is limited, silicon precipitates are present after casting. These silicon precipitates have a platelet shape and a characteristic grain size. It is known that for such alloys the mechanical strength can be increased by solution annealing and quenching. It is further known that this type of increase in strength hinders oxide formation by anodizing.
- DE 4326430 A1 describes a way how an electrolyte can be pumped to delimited surface regions of the substrate and thus anodized locally limited.
- the writings DE 10 2006 051 709 A1 and DE 10 2013 110 659 A1 describe a further alternative, wherein in an oxygen atmosphere by means of a laser, an aluminum alloy substrate is locally melted and the reflow zone reacts with oxygen, ie aluminum oxide is formed in a delimited area by laser processing.
- the present invention relates to a method for producing a patterned oxide layer on a silicon-containing aluminum alloy substrate by laser pretreatment and anodization, and a substrate produced by the method.
- the invention can in principle also be applied to magnesium or titanium alloys.

- a second surface area is melted on the substrate in a second step with a laser.
- a smaller grain size of the silicon precipitates than in the alloy in the first surface area is generated by the melting down to the penetration depth of the laser.
- the substrate is anodized by an immersion bath process, whereby a first oxide layer having a first layer thickness is formed in the first surface region and no oxide layer or a second oxide layer with a lower second layer thickness than the first layer thickness of the first oxide layer is formed in the second surface region.
- a mask in the second step of the method in the second surface area, can be used during the laser processing for further structuring.
- the present invention also relates to an aluminum alloy substrate having a silicon content of 5-15%.
- the substrate has, in a first surface area on the surface, a first oxide layer with a first layer thickness.
- no oxide layer or a lower second layer thickness of a second oxide layer is present as the first layer thickness of the first oxide layer in the first surface area.
- the second surface area at the surface to the penetration depth of the laser within the aluminum alloy on a smaller grain size of the silicon precipitates than in the first surface area. In the second surface area, therefore, lies on the surface up to the penetration depth
- the laser within the aluminum alloy also has a higher hardness than within the aluminum alloy in the first surface area.
- the second surface area advantageously has no oxide layer or at least an order of magnitude lower second layer thickness of the second oxide layer than the first layer thickness of the first oxide layer in the first surface area due to the anodization.
- the invention enables the preparation of a patterned oxide layer on a silicon-containing aluminum alloy substrate by a dipping process without masking, i. it is possible to realize surface areas with significantly different layer thicknesses and resulting different mechanical and electrical properties in a favorable process. For example, in the area of the high layer thickness, high corrosion protection and, in the area of the low layer thickness, a low ohmic resistance for electrical grounding of a component can be realized. In addition, the adhesion of a gasket or adhesive at a lower oxide layer thickness can be improved. Furthermore, lower oxide layer thicknesses facilitate, for example, subsequent exciting machining or welding processes.
- the method according to the invention makes it possible to dispense with a local removal of the oxide layer of an anodized component and an optionally associated additional purification step, thereby simplifying the production.

- Such a laser processing can, for example, be pulsed and carried out with a neodymium-doped yttrium-aluminum-garnet laser.
- the laser processing in the second surface area 204 of the substrate 201 from the surface 202 (see FIG Fig. 2 ) up to the penetration depth 305 (see Fig. 3 ) reduces a grain size of silicon precipitates within the aluminum alloy and thus in this second surface region 204 also a higher hardness than within the aluminum alloy in the first surface region 203 (see Fig. 2 ) reached.
- the substrate 201 is anodized (see Fig. 2 ). By anodizing, a first oxide layer 301 having a first layer thickness 302 is formed on the surface 202 of the substrate 201 in the first surface region 203 (see FIG Fig. 3 ).

- the second surface region 403 there is no oxide in this exemplary embodiment.
- a joining partner 406 is arranged in the second surface area 403, however.
- the joining partner 406 can in this case be attached to the substrate 401 in the second surface area 403, as in FIG Fig. 4 represented, abut and there, for example, with screws, with adhesive or by welding to be fixed (the fixings are not shown).
- the first layer thickness 405 of the first oxide layer 404 is, for example, 20 ⁇ m.
- the electrical resistance between the joining partner 406 and the substrate 401 is low due to the lack of oxide layer in the second surface region 403, which is why the substrate 401 can be electrically contacted by the contact with the joining partner 406.
- the thermal conductivity between the joining partner 406 and the substrate 401 is high, which is why contact with the joining partner 406 in the second surface region 403 can also dissipate heat from the substrate 401.

- a surface 505 of the joining edge at the cap end is melted in a second surface region 503 of the substrate 501, and a smaller grain size of silicon precipitates is thus realized within the aluminum alloy in the second surface region 503 than within the aluminum alloy in the first surface region 503.
- a first oxide layer 504 having a first layer thickness 505 is realized in the first surface region 502.
- the oxide formation in the second surface area 503 is avoided. This enables a better adhesion of an adhesive 504 or a seal in the second surface area 503 than in the first surface area 502.
- the adhesive is electrically conductive as a composite material with metallic particles, so that the adhesive bond also provides a good conductive, electrical contact to the Substrate allows.

Durch Anodisieren wird die Oberfläche eines Substrates aus einer Aluminiumlegierung in eine Aluminiumoxidschicht konvertiert. Bauteile aus anodisiertem Aluminium weisen demnach an der Oberfläche eine Oxidschicht auf. Oxidfreie Oberflächenbereiche können aufgrund des Tauchbadprozesses nur durch Maskierungen oder ein nachträgliches Abtragen der Oxidschicht realisiert werden. Durch eine Laserbearbeitung kann die Oxidschicht eines Bauteils aus anodisiertem Aluminium beispielsweise lokal entfernt werden.Anodizing converts the surface of an aluminum alloy substrate into an aluminum oxide layer. Components made of anodized aluminum accordingly have an oxide layer on the surface. Oxide-free surface areas can be realized only by masking or a subsequent removal of the oxide layer due to the dipping process. By laser processing, the oxide layer of a component made of anodized aluminum, for example, be removed locally.
Für den Druckguss von Gehäusegeometrien eignet sich eine Aluminiumlegierung mit einem Siliziumanteil von z.B. 12%. Da die Löslichkeit von Silizium in einer Aluminiumlegierung begrenzt ist, liegen nach dem Guss Siliziumausscheidungen vor. Diese Siliziumausscheidungen weisen eine Plättchenform und eine charakteristische Korngröße auf. Es ist bekannt, dass für solche Legierungen die mechanische Festigkeit durch Lösungsglühen und Abschrecken gesteigert werden kann. Es ist des Weiteren bekannt, dass diese Art der Festigkeitssteigerung eine Oxidbildung durch Anodisieren behindert.For die casting of housing geometries, an aluminum alloy having a silicon content of e.g. 12%. Since the solubility of silicon in an aluminum alloy is limited, silicon precipitates are present after casting. These silicon precipitates have a platelet shape and a characteristic grain size. It is known that for such alloys the mechanical strength can be increased by solution annealing and quenching. It is further known that this type of increase in strength hinders oxide formation by anodizing.

Die vorliegende Erfindung betrifft ein Verfahren zur Erzeugung einer strukturierten Oxidschicht auf einem Substrat aus einer Silizium-haltigen Aluminiumlegierung durch eine Laservorbehandlung und Anodisieren sowie ein durch das Verfahren erzeugtes Substrat. Die Erfindung ist prinzipiell auch auf Magnesium- oder Titanlegierungen übertragbar.The present invention relates to a method for producing a patterned oxide layer on a silicon-containing aluminum alloy substrate by laser pretreatment and anodization, and a substrate produced by the method. The invention can in principle also be applied to magnesium or titanium alloys.
Im erfindungsgemäßen Verfahren wird in einem ersten Schritt ein Substrat aus einer Aluminiumlegierung mit einem Siliziumanteil von 5 - 15 % bereitgestellt. Anschließend wird auf dem Substrat in einem zweiten Schritt ein zweiter Oberflächenbereich mit einem Laser aufgeschmolzen. Im zweiten Oberflächenbereich wird bis zur Eindringtiefe des Lasers durch das Aufschmelzen eine kleinere Korngröße der Siliziumausscheidungen als in der Legierung im ersten Oberflächenbereich erzeugt. In einem dritten Schritt wird das Substrat durch einen Tauchbadprozess anodisiert, wodurch im ersten Oberflächenbereich eine ersten Oxidschicht mit einer ersten Schichtdicke gebildet wird und im zweiten Oberflächenbereich keine Oxidschicht oder eine zweite Oxidschicht mit einer niedrigeren zweiten Schichtdicke als der ersten Schichtdicke der ersten Oxidschicht entsteht.In the method according to the invention, a substrate made of an aluminum alloy with a silicon content of 5 to 15% is provided in a first step. Subsequently, a second surface area is melted on the substrate in a second step with a laser. In the second surface area, a smaller grain size of the silicon precipitates than in the alloy in the first surface area is generated by the melting down to the penetration depth of the laser. In a third step, the substrate is anodized by an immersion bath process, whereby a first oxide layer having a first layer thickness is formed in the first surface region and no oxide layer or a second oxide layer with a lower second layer thickness than the first layer thickness of the first oxide layer is formed in the second surface region.

Die vorliegende Erfindung betrifft außerdem ein Substrat aus einer Aluminiumlegierung mit einem Siliziumanteil von 5 - 15 %. Das Substrat weist in einem ersten Oberflächenbereich auf der Oberfläche eine erste Oxidschicht mit einer ersten Schichtdicke auf. In einem zweiten Oberflächenbereich liegt keine Oxidschicht oder eine niedrigere zweite Schichtdicke einer zweiten Oxidschicht als die erste Schichtdicke der ersten Oxidschicht im ersten Oberflächenbereich vor. Außerdem weist der zweite Oberflächenbereich an der Oberfläche bis zur Eindringtiefe des Lasers innerhalb der Aluminiumlegierung eine kleinere Korngröße der Siliziumausscheidungen als im ersten Oberflächenbereich auf. Im zweiten Oberflächenbereich liegt deshalb an der Oberfläche bis zur Eindringtiefe des Lasers innerhalb der Aluminiumlegierung auch eine höhere Härte als innerhalb der Aluminiumlegierung im ersten Oberflächenbereich vor. Vorteilhafterweise weist der zweite Oberflächenbereich durch das Anodisieren keine Oxidschicht oder eine um mindestens eine Größenordnung niedrigere zweite Schichtdicke der zweiten Oxidschicht als die erste Schichtdicke der ersten Oxidschicht im ersten Oberflächenbereich auf.The present invention also relates to an aluminum alloy substrate having a silicon content of 5-15%. The substrate has, in a first surface area on the surface, a first oxide layer with a first layer thickness. In a second surface area, no oxide layer or a lower second layer thickness of a second oxide layer is present as the first layer thickness of the first oxide layer in the first surface area. In addition, the second surface area at the surface to the penetration depth of the laser within the aluminum alloy on a smaller grain size of the silicon precipitates than in the first surface area. In the second surface area, therefore, lies on the surface up to the penetration depth The laser within the aluminum alloy also has a higher hardness than within the aluminum alloy in the first surface area. The second surface area advantageously has no oxide layer or at least an order of magnitude lower second layer thickness of the second oxide layer than the first layer thickness of the first oxide layer in the first surface area due to the anodization.
Die Erfindung ermöglicht die Herstellung einer strukturierten Oxidschicht auf einem Substrat aus einer Silizium-haltigen Aluminiumlegierung durch einen Tauchbadprozess ohne Maskierung, d.h. es können Oberflächenbereiche mit deutlich unterschiedlicher Schichtdicke und daraus resultierenden unterschiedlichen mechanischen und elektrischen Eigenschaften in einem günstigen Verfahren realisiert werden. So kann beispielsweise im Bereich der hohen Schichtdicke ein hoher Korrosionsschutz und im Bereich der niedrigen Schichtdicke einen niedriger ohmscher Widerstand zur elektrischen Erdung eines Bauteils realisiert werden. Außerdem kann die Haftung einer Dichtung oder eines Klebers bei niedrigerer Oxidschichtdicke verbessert sein. Des Weiteren erleichtern niedrigere Oxidschichtdicken beispielsweise nachträgliche spannende Bearbeitungs- oder Schweißprozesse.The invention enables the preparation of a patterned oxide layer on a silicon-containing aluminum alloy substrate by a dipping process without masking, i. it is possible to realize surface areas with significantly different layer thicknesses and resulting different mechanical and electrical properties in a favorable process. For example, in the area of the high layer thickness, high corrosion protection and, in the area of the low layer thickness, a low ohmic resistance for electrical grounding of a component can be realized. In addition, the adhesion of a gasket or adhesive at a lower oxide layer thickness can be improved. Furthermore, lower oxide layer thicknesses facilitate, for example, subsequent exciting machining or welding processes.
Gegenüber dem Stand der Technik kann durch das erfindungsgemäße Verfahren auf ein lokales Entfernen der Oxidschicht eines anodisierten Bauteils und auf einen gegebenenfalls damit verbundenen zusätzlichen Reinigungsschritt verzichtet werden, wodurch die Herstellung vereinfacht wird.Compared with the state of the art, the method according to the invention makes it possible to dispense with a local removal of the oxide layer of an anodized component and an optionally associated additional purification step, thereby simplifying the production.
