Abstract

The invention relates to a plastic surface with a coating applied by means of a thermal spray method and a method for the production of said coating. According to the invention, the first step is the production of a primer layer applied to the plastic surface as a base body, by means of a thermal spraying method and then a functional coating is applied to the primer, also produced by means of a thermal spraying method. The primer and the functional coating are differentiated by the material composition thereof. Zinc, zinc alloys, aluminium alloys and/or materials exothermic in the spray method are suitable as primers. The primer is particularly applied by means of arc spraying, flame spraying or cold gas spraying.

Beschreibung description
Kunststoffoberfläche mit thermisch gespritzter Beschichtung und Verfahren zu ihrer HerstellungPlastic surface with a thermally sprayed coating and process for its production
Die Erfindung betrifft eine Kunststoffoberfläche mit zumindest teilweiser Beschichtung, welche mittels thermischer Spritzverfahren aufgetragen ist.The invention relates to a plastic surface with at least partial coating, which is applied by means of thermal spraying processes.
Die Erfindung betrifft ferner ein Verfahren zur Herstellung einer mittels thermischer Spritzverfahren auf einer Kunststoffoberfläche aufgebrachte Beschichtung.The invention further relates to a method for producing a coating applied to a plastic surface by means of thermal spraying methods.
Kunststoffe gewinnen auch heute noch in ihrer industriellen Verwendung zunehmend an Bedeutung. Dabei müssen in vielen Fällen besondere Anforderungen für den Einsatz der Kunststoffe erfüllt werden. Dies geschieht beispielsweise dadurch, dass die Kunststoffe eine Beschichtung aufweisen, welche mittels eines thermischen Spritzverfahrens hergestellt wird.Even today, plastics are becoming increasingly important in their industrial use. In many cases, special requirements for the use of plastics must be met. This happens, for example, in that the plastics have a coating which is produced by means of a thermal spraying process.
Beim Beschichten von Kunststoffen mittels thermischen Spritzen besteht ein Problem im Unterschied zum Beschichten von beispielsweise von Metallen darin, dass eine ausreichende Haftung der Spritzschichten erzielt wird. Es besteht in der Regel die Gefahr, dass die gespritzten Beschichtungen insbesondere bei Belastungen sich vom Grundkörper ablösen.When coating plastics by means of thermal spraying, a problem in contrast to coating metals, for example, is that adequate adhesion of the sprayed layers is achieved. As a rule, there is a risk that the sprayed coatings will become detached from the base body, particularly under loads.
Kunststoffe werden neben anderen Anwendungen insbesondere auch im Bereich von Sportgeräten eingesetzt, auch hier in zunehmendem Maße.In addition to other applications, plastics are also used in the field of sports equipment, to an increasing extent.
Auch bei Golfschlägern geht inzwischen die Entwicklung zumindest in Teilbereichen zum Einsatz von Kunststoffen als Basismaterial insbesondere im Bereich des Schlägerkopfes. Diese Golfschläger mit Kunststoffmaterialien sollen in erster Linie dazu dienen, den Ball extrem weit schlagen zu können.Golf clubs are also developing, at least in some areas, to use plastics as the base material, particularly in the area of the club head. These golf clubs with plastic materials are primarily intended to be able to hit the ball extremely far.
Das Beschichten von Golfschlägern mittels Thermischen Spritzens ist an sich bekannt. Aus der eigenen deutschen Patentanmeldung DE 19757736 A1 ist beispielsweise ein Golfschläger mit Schlagfläche zum Schlagen von Golfbällen beschrieben, der zumindest im Bereich der Schlagfläche eine mittels eines thermischen Spritzverfahrens aufgebrachte Beschichtung umfasst. Angesprochen sind hier Golfschläger aus den üblichen Materialien, d.h. aus Metallen oder Metalllegierungen. Die Schlägerbeschichtungen werden bevorzugt mittels des Hochgeschwindigkeits-Flammspritzverfahrens oder mittels des Kaltgasspritzverfahrens aufgebracht. Für die Beschichtung der Golfschläger mittels thermischen Spritzens können als Spritzmaterialien insbesondere Metalle, Metalllegierungen, Oxide (insbesondere AI2O3 und/oder TiO2), Carbide, Boride, Kunststoffe oder Mischungen der vorgenannten Stoffe verwendet werden.The coating of golf clubs by means of thermal spraying is known per se. From the own German patent application DE 19757736 A1, for example, a golf club with a striking surface for hitting golf balls is described, which, at least in the area of the striking surface, by means of a thermal spraying process applied coating comprises. Golf clubs made from the usual materials, ie from metals or metal alloys, are addressed here. The club coatings are preferably applied by means of the high-speed flame spraying process or by means of the cold gas spraying process. Metals, metal alloys, oxides (in particular Al 2 O 3 and / or TiO 2 ), carbides, borides, plastics or mixtures of the aforementioned substances can be used as spray materials for the coating of the golf clubs by means of thermal spraying.
Bei Golfschlägern für weite Schläge soll die durch den Schwung des Golfspielers aufgebrachte Energie optimal über den Schlägerkopf auf den Golfball umgesetzt werden. Dabei entstehen enorme Kräfte, die punktförmig und möglicherweise durch Deformieren des Balls auch in gewisser Weise flächenförmig auf der Schlagfläche des Golfschlägers angreifen.In golf clubs for long shots, the energy applied by the swing of the golfer should be optimally transferred to the golf ball via the club head. This creates enormous forces that act punctiformly and possibly to a certain extent on the face of the golf club by deforming the ball.
Der Golfschlägerkopf mit Kunststoff muss diesen extremen Anforderungen beim Schlag standhalten. Zusätzlich ist eine verschleißbeständige Beschichtung vorzusehen,~damit beispielsweise wegen der Berührungen des Schlägers mit dem Boden beim Schlagen des Balles ein Verschleiß des Golfschlägerkopfes vermieden wird.The golf club head with plastic has to withstand these extreme requirements when striking. In addition, a wear-resistant coating is provided, ~ is thus avoided, for example wear of the golf club head due to the touch of the stick with the ground when striking the ball.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Kunststoffoberfläche und ein Verfahren der eingangs genannten Art aufzuzeigen, welche eine thermisch gespritzte Beschichtung auf der Kunststoffoberfläche mit guter Haftung ermöglichen.The invention is therefore based on the object of demonstrating a plastic surface and a method of the type mentioned at the outset, which enable a thermally sprayed coating on the plastic surface with good adhesion.
Diese Aufgabe wird für die Kunststoffoberfläche dadurch gelöst, dass die Beschichtung zumindest eine als Haftgrund mittels eines thermischen Spritzverfahrens auf der Kunststoffoberfläche als Grundkörper aufgetragene Schicht und auf dem Haftgrund eine mittels eines thermischen Spritzverfahrens erzeugte Beschichtung umfasst, wobei sich der Haftgrund hinsichtlich seiner materiellen Zusammensetzung von der Beschichtung unterscheidet.This object is achieved for the plastic surface in that the coating comprises at least one layer applied as a primer by means of a thermal spraying process on the plastic surface as a base body and on the primer a coating produced by means of a thermal spraying method, the primer base differing in terms of its material composition from the Coating differs.
Diese Aufgabe wird für das Verfahren dadurch gelöst, dass die Herstellung zumindest die folgenden Verfahrensschritte umfasst:This object is achieved for the method in that the production comprises at least the following process steps:
(a) Auftragen einer Schicht als Haftgrund mittels eines thermischen Spritzverfahrens auf der Kunststoffoberfläche als Grundkörper und (b) Auftragen einer Beschichtung insbesondere als Verschleißschutzschicht mittels eines thermischen Spritzverfahrens auf der mit Haftgrund versehenen Oberfläche.(a) applying a layer as a primer by means of a thermal spraying process on the plastic surface as the base body and (b) Applying a coating, in particular as a wear protection layer, by means of a thermal spraying process to the surface provided with a primer.
Die Erfindung basiert auf der Idee, dass die Kunststoffoberfläche zunächst mit einer thermisch gespritzten Haftschicht (Haftvermittler) versehen wird und anschließend erst die für die Anwendung benötigte Funktionsbeschichtung (beispielsweise eine Ver- schleißschutzbeschichtung) aufgetragen wird.The invention is based on the idea that the plastic surface is first provided with a thermally sprayed adhesive layer (adhesion promoter) and only then is the functional coating required for the application (for example a wear protection coating) applied.
Im Rahmen der Erfindung können zum Auftragen der Funktionsbeschichtung grundsätzlich alle bekannten Verfahrensvarianten des Thermischen Spritzens eingesetzt werden.In principle, all known process variants of thermal spraying can be used for applying the functional coating.
Zum Aufbringen der Schicht als Haftgrund einerseits und der Beschichtung (Funktions- beschichtung z.B. als verschleißbeständige Schutzschicht) andererseits können unterschiedliche oder gleiche Verfahrensvarianten des Thermischen Spritzens zum Einsatz kommen.To apply the layer as a primer on the one hand and the coating (functional coating e.g. as a wear-resistant protective layer) on the other hand, different or the same process variants of thermal spraying can be used.
In Ausgestaltung der Erfindung umfasst der Haftgrund Zink, Zinklegierungen, Alumini- umlegierungen und/oder beim Spritzprozess exotherm wirkende Materialien wie beispielsweise Nickel-Aluminium (NiAl) oder Molybdän (Mo). Denn es hat sich gezeigt, dass durch das Verspritzen dieser Werkstoffe die Haftung der thermisch gespritzten Beschichtung wesentlich erhöht werden kann.In one embodiment of the invention, the primer comprises zinc, zinc alloys, aluminum alloys and / or materials which have an exothermic effect during the spraying process, such as nickel aluminum (NiAl) or molybdenum (Mo). It has been shown that spraying these materials can significantly increase the adhesion of the thermally sprayed coating.
Der Haftgrund kann insbesondere mittels Lichtbogenspritzens, Flammspritzens oder Kaltgasspritzens als Verfahrensvarianten des Thermischen Spritzens aufgetragen werden.The primer can be applied in particular by means of arc spraying, flame spraying or cold gas spraying as process variants of thermal spraying.
In Weiterbildung der Erfindung kann der thermisch beschichtete Kunststoff aus einem faserverstärkten Kunststoff bestehen. Als faserverstärkte Kunststoffe kommen dabei insbesondere Kunststoffe mit Kohlenstofffasern (CFK), mit (Para-)Aramidfasem (KEVLAR®), mit Glasfasern (GFK) und dergleichen in Betracht.In a development of the invention, the thermally coated plastic can consist of a fiber-reinforced plastic. As fiber-reinforced plastics are in particular plastics with carbon fiber (CFRP), with (para-) aramide (KEVLAR ®), glass fiber (GRP) and the like into consideration.
Die genannten Kunststoffe eignen sich hervorragend für den Einsatz im Zusammen- hang mit Sportgeräten. Dabei sind insbesondere Golfschläger zu nennen. Die Golfschläger sind im Rahmen der Erfindung vor allem im Bereich des Golfschlägerkopfes und hier insbesondere im Bereich der Schlagfläche zumindest teilweise mit einer thermisch gespritzten Beschichtung versehen.The plastics mentioned are ideal for use in connection with sports equipment. Golf clubs should be mentioned in particular. Within the scope of the invention, the golf clubs are at least partially provided with a thermally sprayed coating, particularly in the area of the golf club head and here in particular in the area of the club face.
Als Gase für das Thermische Spritzen im Rahmen der Erfindung kommen grundsätzlich alle bekannten Gase in Betracht, insbesondere Stickstoff, Argon, Helium, Neon, Krypton, Xenon, ein Wasserstoff enthaltendes Gas, ein kohlenstoffhaltiges Gas, insbesondere Kohlendioxid, Sauerstoff, ein Sauerstoff enthaltendes Gas, Luft, Wasserdampf oder Mischungen der vorgenannten Gase.In principle, all known gases are suitable as gases for thermal spraying in the context of the invention, in particular nitrogen, argon, helium, neon, krypton, xenon, a gas containing hydrogen, a gas containing carbon, in particular carbon dioxide, oxygen, a gas containing oxygen, Air, water vapor or mixtures of the aforementioned gases.
Für den Fall, dass der Haftgrund mittels Lichtbogenspritzen aufgetragen wird, hat sich gezeigt, dass Stickstoff als Treibgas besondere Vorteile mit sich bringt.In the event that the primer is applied by means of arc spraying, it has been shown that nitrogen as a propellant gas has special advantages.
Für den Fall, dass der Haftgrund mittels Flammspritzens aufgetragen wird, wird vorteilhafterweise hinsichtlich des Verhältnisses von Brenngas zu Sauerstoff eine neutrale oder auch eine reduzierte Flammeneinstellung verwendet.In the event that the primer is applied by flame spraying, a neutral or else a reduced flame setting is advantageously used with regard to the ratio of fuel gas to oxygen.
Für das Kaltgasspritzen eignen sich für das den pulverförmigen Zusatzwerkstoff tragende Gas neben den aus der EP 0484533 B1 bekannten Gasen Luft und/oder Helium ein Stickstoff, Argon, Neon, Krypton, Xenon, Sauerstoff, ein Wasserstoff enthaltendes Gas, ein kohlenstoffhaltiges Gas, insbesondere Kohlendioxid, Wasserdampf oder Mischungen der vorgenannten Gase und Mischungen dieser Gase mit Helium. Der Anteil des Helium am Gesamtgas kann bis zu 90 Vol.-% betragen. Bevor- zugtwird ein Heliumanteil von 10 bis 50 Vol.-% im Gasgemisch eingehalten. For cold gas spraying, in addition to the gases air and / or helium known from EP 0484533 B1, a nitrogen, argon, neon, krypton, xenon, oxygen, a hydrogen-containing gas and a carbon-containing gas, in particular carbon dioxide, are suitable for the gas carrying the powdered filler material , Water vapor or mixtures of the aforementioned gases and mixtures of these gases with helium.
