Die Erfindung betrifft einen Golfschläger mit Schlagfläche zum Schlagen von Golfbällen.The invention relates to a golf club with a face for hitting Golf balls.

Beim Golfspielen ist es wichtig, den Golfball aus den unterschiedlichsten Situationen heraus unter Berücksichtigung der Entfernung, des Untergrundes, etwaiger Hindernisse etc. möglichst kontrolliert in Richtung des Loches schlagen zu können. Um diesen unterschiedlichen Anforderungen gerecht werden zu können, werden gewöhnlich verschiedenartige Golfschläger eingesetzt. Der Spieler wählt üblicherweise den für anstehenden Schlag seiner Meinung nach geeigneten Schläger aus. Die einzelnen Schläger unterscheiden sich dabei in der Regel hinsichtlich des Schlägermaterials, zumindest im Bereich des Schlägerkopfes, der die Schlagfläche enthält, des Anstellwinkels der Schlagfläche und der Oberflächenbeschaffenheit im Bereich der Schlagfläche.When playing golf it is important to get the golf ball out of different situations out taking into account the distance, the surface, any obstacles etc. to be able to hit in the direction of the hole as controlled as possible. Around It is common to be able to meet these different requirements different types of golf clubs used. The player usually chooses in his opinion, the club suitable for the upcoming shot. The individual racquets usually differ in terms of the racquet material, at least in the area of the club head that contains the club face, the angle of attack of the face and the surface quality in the area the face.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, Golfschläger hinsichtlich ihrer Schlageigenschatten weiter zu verbessern und sie vor allem im Bereich ihrer Schlagfläche so auszugestalten, daß die Möglichkeiten, Fähigkeiten und Eignungen für bestimmte Einsatzfälle vergrößert werden. Es sollten einerseits möglichst Schläger zur Verfügung gestellt werden, die auch besonders weite Schläge zulassen oder gar überhaupt erst ermöglichen. Auf der anderen Seite sollten aber auch Schläger für gefühlvolle weiche Schläge über geringe Entfernungen bereitgestellt werden. Schließlich sollten auch Golfschläger für Schläge mit Drall aufgezeigt werden.The present invention has for its object golf clubs in terms of their Hit shadows continue to improve and especially in the area of their face To be designed so that the possibilities, skills and suitability for certain Use cases are enlarged. On the one hand, rackets should be used Be made available, which also allow particularly long blows or even enable in the first place. On the other hand, clubs should also be used for soulful soft blows can be provided over short distances. Finally golf clubs should also be shown for swings with twist.

Die gestellte Aufgabe wird dadurch gelöst, daß der Golfschläger zumindest im Bereich der Schlagfläche eine mittels eines thermischen Spritzverfahrens aufgebrachte Beschichtung umfaßt.The task is solved in that the golf club at least in Area of the striking surface applied by means of a thermal spraying process Coating includes.

Der Vorteil der Erfindung liegt darin, daß durch die Herstellung der Beschichtung des Golfschlägers unter Anwendung eines thermischen Spritzverfahrens eine weite Palette an Golfschlägern unterschiedlichster Eigenschaften der Beschichtung zur Verfügung gestellt werden kann, welche eine optimale Anpassung der Eigenschaften und insbesondere der Oberflächeneigenschaften der Schlagfläche zusätzlich zu den Möglichkeiten erlaubt, die durch die Wahl des Materials des Schlägers und insbesondere des Schlägerkopfes ohnehin schon geboten werden. Thermische Spritzverfahren bieten die Möglichkeiten der Herstellung von Schlägerbeschichtungen aus den unterschiedlichsten Materialien, wobei die thermischen Spritzverfahren Schichtzusammensetzungen ermöglichen, die andere Herstellungsverfahren von Beschichtungen nicht zulassen.The advantage of the invention is that by producing the coating of the Golf club using a thermal spray process a long way Range of golf clubs with various properties of the coating for Can be made available, which optimal adjustment of the properties and in particular the surface properties of the club face in addition to Opportunities allowed by the choice of the material of the racket and in particular of the club head are already offered anyway. Thermal spraying process offer the possibility of producing racket coatings from the different materials, with the thermal spraying layer compositions enable the other manufacturing processes of coatings not allow.

Thermische Spritzverfahren zeichnen sich im wesentlichen dadurch aus, daß siegleichmäßig aufgetragene Beschichtungen von hoher Qualität und Güte ermöglichen. Durch thermische Spritzverfahren aufgetragene Beschichtungen können durch Variation der Spritzmaterialien und/oder der Verfahrensparameter an unterschiedliche Anforderungen angepaßt werden. Die Spritzmaterialien können dabei in Form von Drähten, Stäben oder als Pulver verarbeitet werden. Es kann zusätzlich eine Nachbehandlung vorgesehen sein.Thermal spray processes are essentially characterized by the fact that they are uniform enable applied coatings of high quality and quality. Coatings applied by thermal spraying can be varied the spray materials and / or the process parameters to different Requirements are adjusted. The spray materials can be in the form of Wires, rods or processed as powder. There can also be an aftercare be provided.

In jüngerer Zeit wurde darüber hinaus ein weiteres thermisches Spritzverfahren entwickelt, welches auch als Kaltgasspritzen bezeichnet wird. Es handelt sich dabei um eine Art Weiterentwicklung des Hochgeschwindigkeits-Flammspritzens. Dieses Verfahren ist beispielsweise in der europäischen Patentschrift EP 0 484 533 B1 beschrieben. Beim Kaltgasspritzen kommt ein Zusatzwerkstoff in Pulverform zum Einsatz. Die Pulverpartikel werden beim Kaltgasspritzen jedoch nicht im Gasstrahl geschmolzen. Vielmehr liegt die Temperatur des Gasstrahles unterhalb des Schmelzpunktes der Zusatzwerkstoffpulverpartikel (EP 0 484 533 B1). Im Kaltgasspritzverfahren wird also ein im Vergleich zu den herkömmlichen Spritzverfahren "kaltes" bzw. ein vergleichsweise kälteres Gas verwendet. Gleichwohl wird das Gas aber ebenso wie in den herkömmlichen Verfahren erwärmt, aber in der Regel lediglich auf Temperaturen unterhalb des Schmelzpunktes der Pulverpartikel des Zusatzwerkstoffes.Recently, another thermal spraying process has also been developed which is also known as cold gas spraying. It is about a kind of further development of high-speed flame spraying. This method is described, for example, in European Patent EP 0 484 533 B1. A filler material in powder form is used for cold gas spraying. The However, powder particles are not melted in a gas jet during cold gas spraying. Rather, the temperature of the gas jet is below the melting point of the Filler powder particles (EP 0 484 533 B1). So in the cold gas spraying process a "cold" or a comparative compared to the conventional spraying process colder gas used. Nevertheless, the gas is used just like in the conventional processes heated, but usually only to temperatures below the melting point of the powder particles of the filler material.

Je nach dem verwendeten thermischen Spritzverfahren ergibt sich eine bestimmte Beschichtung des Golfschlägers mit bestimmten Eigenschaften. Die besten Ergebnisse konnten erzielt werden, wenn die Beschichtung mittels des Hochgeschwindigkeits-Flammspritzverfahrens oder mittels des Kaltgasspritzverfahrens aufgebracht wird. Als Hochgeschwindigkeits-Flammspritzverfahren können das Hochgeschwindigkeits-Flammspritzen der ersten Generation mit Spritzpartikelgeschwindigkeiten bis 350 m/s, das Hochgeschwindigkeits-Flammspritzen der zweiten Generation mit Spritzpartikelgeschwindigkeiten zwischen 350 und 650 m/s und bevorzugt das Hochgeschwindigkeits-Flammspritzen der dritten Generation mit Spritzpartikelgeschwindigkeiten über 650 m/s zum Einsatz kommen. Beim Kaltgasspritzen können die Pulverpartikel auf eine Geschwindigkeit von 300 bis 1600 m/s beschleunigt werden. Es eignen sich dabei insbesondere Geschwindigkeiten der Pulverpartikel zwischen 1000 und 1600 m/s, besonders bevorzugt zwischen 1250 und 1600 m/s, da in diesem Fall die Energieübertragung in Form von kinetischer Energie besonders hoch ausfällt.Depending on the thermal spraying process used, there is a specific one Coating the golf club with certain properties. The best results could be achieved when coating using the high speed flame spray process or applied by means of the cold gas spraying process becomes. As a high-speed flame spraying process, high-speed flame spraying can be used the first generation with spray particle speeds up to 350 m / s, the second-generation high-speed flame spraying with spray particle speeds between 350 and 650 m / s and prefers high-speed flame spraying the third generation with spray particle speeds over 650 m / s are used. With cold gas spraying, the powder particles can accelerated to a speed of 300 to 1600 m / s. It Speeds of the powder particles between 1000 are particularly suitable and 1600 m / s, particularly preferably between 1250 and 1600 m / s, since in this case the energy transfer in the form of kinetic energy is particularly high.

Für die Beschichtung der Golfschläger mittels thermischen Spritzens können als Spritzmaterialien insbesondere Metalle, Metallegierungen, Oxide (insbesondere Al2O3 und/oder TiO2), Carbide, Boride, Kunststoffe oder Mischungen der vorgenannten Stoffe verwendet werden.Metals, metal alloys, oxides (in particular Al 2 O 3 and / or TiO 2 ), carbides, borides, plastics or mixtures of the abovementioned substances can be used as spray materials for the coating of the golf clubs by means of thermal spraying.

Zur Herstellung der Golfschläger mittels der thermischen Spritzverfahren wird bevorzugt ein Pulver eingesetzt. Insbesondere eignen sich Pulver mit Partikelgrößen von 1 µm bis 1 mm, besonders bevorzugt mit 5 bis 100 µm. For the production of golf clubs by means of the thermal spraying process is preferred a powder is used. Powders with particle sizes of are particularly suitable 1 µm to 1 mm, particularly preferably 5 to 100 µm.

Als Gase für das thermische Spritzen kommen beispielsweise Stickstoff, Helium, Argon, Neon, Krypton, Xenon, ein Wasserstoff enthaltendes Gas, ein kohlenstoffhaltiges Gas, insbesondere Kohlendioxid, Sauerstoff, ein Sauerstoff enthaltendes Gas, Luft oder Mischungen der vorgenannten Gase in Frage. Neben den aus der EP 0 484 533 B1 bekannten Gasen Luft und/oder Helium eignen sich auch für das den pulverförmigen Zusatzwerkstoff tragende Gas ein Stickstoff, Argon, Neon, Krypton, Xenon, Sauerstoff, ein Wasserstoff enthaltendes Gas, ein kohlenstoffhaltiges Gas, insbesondere Kohlendioxid, oder Mischungen der vorgenannten Gase und Mischungen dieser Gase mit Helium. Der Anteil des Helium am Gesamtgas kann bis zu 90 Vol.-% betragen. Bevorzugt wird ein Heliumanteil von 10 bis 50 Vol.-% im Gasgemisch eingehalten.For example, nitrogen, helium, Argon, neon, krypton, xenon, a gas containing hydrogen, a carbon-containing one Gas, especially carbon dioxide, oxygen, an oxygen-containing Gas, air or mixtures of the aforementioned gases in question. In addition to those from the Gases known from EP 0 484 533 B1, air and / or helium, are also suitable for the the powder carrying the filler material is nitrogen, argon, neon, Krypton, Xenon, oxygen, a gas containing hydrogen, a carbon-containing one Gas, especially carbon dioxide, or mixtures of the aforementioned gases and Mixtures of these gases with helium. The proportion of helium in the total gas can be up to 90% by volume. A helium content of 10 to 50% by volume in the gas mixture is preferred adhered to.

Es hat sich gezeigt, daß durch den Einsatz dieser unterschiedlichen Gase und Gasgemischen zum Beschleunigen und Tragen eines pulverförmigen Zusatzwerkstoffes bzw. Spritzmaterials die Flexibilität und Wirksamkeit des thermischen Spritzverfahrens beim Beschichten von Golfschlägern wesentlich vergrößert werden kann. Die so hergestellten Schichten haften sehr gut auf den verschiedensten Substratwerkstoffen, beispielsweise auf den Metallen oder Metallegierungen der Golfschläger und insbesondere des Schlägerkopfes im Bereich der Schlagfläche. Die Beschichtungen sind von hoher Güte, weisen eine außerordentlich geringe Porosität auf und besitzen derartige Spritzoberflächen, daß sich in der Regel eine Nacharbeitung erübrigt. Die erwähnten Gase besitzen eine ausreichende Dichte und Schallgeschwindigkeit, um die erforderlichen hohen Geschwindigkeiten der Pulverpartikel insbesondere beim Kaltgasspritzen gewährleisten zu können. Das Gas kann dabei inerte und/oder reaktive Gase enthalten.It has been shown that by using these different gases and gas mixtures for accelerating and carrying a powdered filler material or spray material the flexibility and effectiveness of the thermal spray process can be significantly enlarged when coating golf clubs. The so produced Layers adhere very well to a wide variety of substrate materials, for example on the metals or metal alloys of the golf clubs and in particular of the club head in the area of the club face. The coatings are of high quality, have an extremely low porosity and have such Spray surfaces that usually make rework unnecessary. The mentioned Gases have a sufficient density and speed of sound in order to required high speeds of the powder particles, especially when cold gas spraying to be able to guarantee. The gas can be inert and / or reactive Contain gases.

Die Erfindung bietet die Möglichkeit, Golfschläger mit Schlagflächen mit vergleichsweise hoher Federenergie bereitzustellen. Diese werden bevorzugt zum weiten Schlagen eingesetzt (sogenannte Patter). Es hat sich gezeigt, daß diese erfindungsgemäßen Golfschläger extrem weite Schläge ermöglichen, die trotz der größeren Weite nicht unkontrollierter werden.The invention offers the possibility of comparing golf clubs with club faces with to provide high spring energy. These are preferred for wide Beating used (so-called patter). It has been shown that these according to the invention Golf clubs allow extremely long shots despite the larger ones Far from becoming uncontrolled.

Mittels thermischer Spritzverfahren, insbesondere mittels des Hochgeschwindigkeits-Flammspritzverfahrens oder mittels des Kaltgasspritzverfahrens können auch weiche Beschichtung aufgebracht werden. Die so ausgestatteten Golfschläger sind in erster Linie für gefühlvolle Schläge über kürzere Distanzen und insbesondere zum Einputten gedacht.By means of thermal spray processes, in particular by means of the high-speed flame spray process or by means of the cold gas spray process, soft ones can also be used Coating can be applied. The golf clubs equipped in this way are first Line for sensitive strokes over short distances and especially for putting thought.

Durch thermisch gespritzte Beschichtungen auf Golfschlägern können die Haftreibungskoeffizienten gegenüber herkömmlichen Golfschlägern erhöht werden. Dies liegt daran, daß durch geeignete ein hoher Haftreibungskoeffizient der Beschichtung im Bereich der Schlagfläche gegenüber dem Golfball erzielt werden kann. Mit derartigen Golfschlägern können Schläge mit Drall (z.B. Hook, Slice, Backspinn) problemlos ausgeführt werden.Thermally sprayed coatings on golf clubs can reduce the static friction coefficient compared to conventional golf clubs. This is that a suitable high coefficient of static friction of the coating can be achieved in the area of the face compared to the golf ball. With such Golf clubs can easily make swings with twists (e.g. hook, slice, backspinn) be carried out.

Die thermisch gespritzte Beschichtung kann für den Golfschläger - gegebenenfalls auch zusätzlich zu anderen Eigenschaften - als Gleitschutz und/oder als Verschleißschutz dienen.The thermally sprayed coating can - if necessary - for the golf club also in addition to other properties - as anti-slip and / or wear protection to serve.

In praktischen Tests haben sich beispielsweise Golfschläger mit thermisch gespritzten Beschichtungen im Bereich der Schlagfläche hervorragend bewährt, deren Spritzbeschichtungen WCCo enthielten.In practical tests, for example, golf clubs with thermally sprayed Coatings in the area of the club face have proven themselves, their spray coatings WCCo included.
