Die Erfindung betrifft ein Verfahren zum Überziehen eines Metallkörpers, insbesondere eines Flugzeugpropellerblattes aus Aluminium, mit einer erosionsbeständigen Schutzschicht durch Flammspritzen unter Verwendung einer Kunstharzzwischenschicht. The invention relates to a method for coating a metal body, in particular one Aircraft propeller blade made of aluminum, with an erosion-resistant protective layer from flame spraying using an intermediate synthetic resin layer.
Es ist bereits bekannt, aus Metalloxyden bzw. Hartmetallen bestehende Schutzüberzüge unter Anordnung von Zwischenschichten durch Flammspritzen auf Gegenstände aufzubringen. Die Zwischenschichten bei dem bekannten Verfahren bestehen aus einer Legierung von Eisen, Kobalt oder Nickel bzw. aus einer Kunstharzschicht. Es ist auch schon bekannt, Spritzmetallüberzüge noch zusätzlich mit einer Lack- bzw. Kunstharzschicht zu versehen.It is already known to arrange protective coatings consisting of metal oxides or hard metals to apply intermediate layers to objects by flame spraying. The intermediate layers in the known method consist of an alloy of iron, cobalt or nickel or from a synthetic resin layer. It is also already known to additionally use spray metal coatings to be provided with a lacquer or synthetic resin layer.
Bei anderen bekannten Auftragungsverfahren für Metallkörper wird die Grundmetalloberfläche gereinigt und durch Stahlkies oder Standstrahl aufgerauht, wodurch eine sehr griffige Oberfläche für das flammgespritzte Material geschaffen wird.In other known application methods for metal bodies, the base metal surface is cleaned and roughened by steel gravel or standing jet, creating a very grippy surface for the flame-sprayed material is created.
In vielen Fällen ist es jedoch unerwünscht, die Oberfläche des Grundmetalls in irgendeiner Weise mechanisch zu behandeln, obwohl eine starke Haftung erforderlich ist. Außerdem ist es gelegentlich notwendig, daß derartige Überzüge ohne Beschädigung des Grundmaterials wieder entfernt werden können, was bei bekannten Verfahren zur Aufbringung von flammgespritzten Überzügen nicht möglich ist. Überdies kann die direkte Auftragung des flammgespritzten Überzuges auf das Grundmetall deswegen unerwünscht sein, da als Folge der Porosität des Überzuges Korrosionsprobleme entstehen.In many cases, however, it is undesirable to surface the base metal in any way to be treated mechanically, although a strong bond is required. Besides, it is occasional It is necessary that such coatings are removed again without damaging the base material can, which is not possible with known methods for applying flame-sprayed coatings is. In addition, direct application of the flame sprayed coating to the base metal can be avoided be undesirable since corrosion problems arise as a result of the porosity of the coating.
Derartige Schwierigkeiten treten insbesondere bei Flugzeugpropellerblättern aus einer Aluminiumlegierung auf. Während Propellerblätter aus einer Aluminiumlegierung ziemlich fest und leicht sind, sind sie nicht sehr widerstandsfähig gegen Schäden durch Partikeln von Wasser, Sand, Steinen und anderen sich in der Luft befindenden Teilchen, welche besonders zahlreich im Bereich der Rollbahnen vorkommen. Um Propellerblätter aus einer Aluminiumlegierung zu schützen, wurden schon Nickelüberzüge aufgebracht; dieses Verfahren ist jedoch teuer und nicht ganz zufriedenstellend. Flammgespritztes Aluminiumoxyd ergibt dagegen eine hervorragend erosionsbeständige Oberfläche; wie gesagt können jedoch bekannte Auftragungsverfahren ohne mechanische Verletzung der Blattoberfläche keinen stark haftenden Überzug herstellen. Auch die Verwendung einer Zwischenschicht aus Kunstharz führt noch nicht zur Überwindung der Schwierigkeiten, da die Haftung des äußeren Überzuges nicht ausreichend ist.Such difficulties occur in particular with aircraft propeller blades made of an aluminum alloy on. While aluminum alloy propeller blades are quite strong and light, they are they are not very resistant to damage from particles of water, sand, stones and others Particles in the air, which are particularly numerous in the area of the taxiways. Nickel coatings have already been used to protect propeller blades made of an aluminum alloy applied; however, this method is expensive and not entirely satisfactory. Flame-sprayed aluminum oxide on the other hand results in an excellent erosion-resistant surface; as I said can however, known application methods without mechanical damage to the leaf surface are not severe make an adhesive coating. The use of an intermediate layer made of synthetic resin also still works not to overcome the difficulties, since the adhesion of the outer coating is insufficient.

Vorzugsweise wird das pulverförmige Metall auf die Kunstharzoberfläche vor ihrer Verfestigung aufgebracht. Das pulverförmige Metall kann dem Kunstharz als Füllstoff zugemischt und die Oberfläche der Harzschicht nach Verfestigung aufgerauht werden.Preferably, the powdered metal is on applied to the synthetic resin surface before it solidifies. The powdery metal can be added to the synthetic resin as a filler and the surface the resin layer can be roughened after solidification.
Bei einer bevorzugten Abwandlung des Verfahrens gemäß der Erfindung wird als pulverförmiges Metall Aluminium oder eine Aluminiumlegierung verwendet. Auf die Kunstharzschicht kann eine Metallschicht aus Aluminium oder aus einer Aluminiumlegierung aufgespritzt werden.In a preferred modification of the method according to the invention, the powdered metal is used Aluminum or an aluminum alloy is used. A metal layer can be applied to the synthetic resin layer Aluminum or an aluminum alloy can be sprayed on.
Als schlagfeste Schicht wird vorzugsweise Aluminiumoxyd aufgespritzt. Das aufgebrachte Kunstharz kann ein Epoxydharz sein.Aluminum oxide is preferably sprayed on as an impact-resistant layer. The applied synthetic resin can be an epoxy resin.
Bei einer bevorzugten Ausführungsform wird auf die schlagfeste Schicht eine abdichtende Schicht eines Kunstharzes aufgebracht.In a preferred embodiment, a sealing layer is applied to the impact-resistant layer Resin applied.
Im folgenden werden Ausführungsbeispiele der Erfindung erläutert.The following are exemplary embodiments of the invention explained.
Ein Propellerblatt aus einer Aluminiumlegierung, welches den Metallgrund darstellt, wird gründlich gereinigt, nachdem seine Oberfläche eloxiert wurde. Die Oberfläche wird dann mit Chromat grundiert, um sie gegen Korrosion durch Wasser zu schützen und die Hafteigenschaften für Kunstharz zu verbessern. Auf die gereinigte und grundierte Oberfläche des Propellerblattes wird dann eine Schicht von Kunstharz aufgetragen. Das Kunstharz ist ein Epoxydharz, im besonderen ein flüssiges Harz. Das Harz wird in einer Schicht von etwa 0,05 bis 0,3 mm vorzugsweise von 0,13 mm Stärke aufgespritzt.A propeller blade made of an aluminum alloy, which is the metal base, is thoroughly cleaned, after its surface has been anodized. The surface is then primed with chromate to make it to protect against corrosion by water and to improve the adhesive properties for synthetic resin. on the cleaned and primed surface of the propeller blade then becomes a layer of synthetic resin applied. The synthetic resin is an epoxy resin, in particular a liquid resin. The resin is in a A layer of about 0.05 to 0.3 mm, preferably 0.13 mm thick, is sprayed on.
Nach der Auftragung und vor der Verfestigung wird eine Schicht von .Metallpulver aus Aluminium oder einer Aluminiumlegierung auf die Oberfläche des Harzes aufgebracht, wobei vorzugsweise Partikeln bis zu einer Tiefe von zwei Dritteln ihres Durchmessers herausragen.After application and before solidification, a layer of metal powder made of aluminum or an aluminum alloy applied to the surface of the resin, preferably particles up to protrude to a depth of two thirds of their diameter.
Nachdem die Schicht aus Kunstharz trocken ist, wird sie durch Erhitzen des Blattes auf Temperaturen in dem Bereich zwischen 50 und 100° C verfestigt. Diese geringe Verfestigungstemperatur beeinflußt nicht die physikalischen Eigenschaften des Blattes. Die Verfestigungszeit bei dieser Temperatur hängt von den Daten ab, die von dem Hersteller des Harzes angegeben werden. Auf die herausragenden Partikeln der Schicht aus pulverförmigem Aluminium oder einer pulverförmigen Aluminiumlegierung, die an der Schicht aus Kunstharz haftet, wird dann ein Überzug aus Aluminium oder einer Aluminiumlegierung aufgespritzt. Das Flammspritzen von Metallen ist bekannt; vorzugsweise wird das Metalldraht verwendende Verfahren benutzt.After the layer of synthetic resin is dry, it is heated by heating the sheet to temperatures solidified in the range between 50 and 100 ° C. This low solidification temperature affects not the physical properties of the sheet. The solidification time at this temperature depends on the data given by the manufacturer of the resin. On the outstanding particles the layer of powdered aluminum or a powdered aluminum alloy attached to the If a layer of synthetic resin adheres, a coating of aluminum or an aluminum alloy is then sprayed on. The flame spraying of metals is known; preferably the metal wire is used Procedure used.
Dann wird eine schlagfeste Schicht von geschmolzenem Metalloxyd odes Kombinationen von Siliziumdioxyd enthaltenden Metalloxyden auf die Oberfläche des gespritzten Überzuges aus Aluminium oder einer Aluminiumlegierung aufgebracht. Die Schicht besteht zweckmäßig aus geschmolzenem Aluminiumoxyd. Das hierfür bevorzugte Auftragungsverfahren ist in der USA.-Patentschrift 2 707 691 beschrieben.Then an impact-resistant layer of molten metal oxide or combinations of silicon dioxide is applied containing metal oxides on the surface of the sprayed coating made of aluminum or a Aluminum alloy applied. The layer expediently consists of molten aluminum oxide. The preferred application method for this is described in US Pat. No. 2,707,691.
Die schlagfeste Schicht hat eine Stärke zwischen 0,25 und 0,63 mm, vorzugsweise von 0,38 mm.The impact-resistant layer has a thickness between 0.25 and 0.63 mm, preferably 0.38 mm.
Anschließend wird eine weitere Schicht von Epoxydharz auf die schlagfeste Schicht aufgebracht und verfestigt. Diese Schicht hat eine Stärke zwischen 0,05 und 0,13 mm, vorzugsweise von 0,076 mm. Sie bewirkt eine Abdichtung der gegebenenfalls porösen Oberfläche der schlagfesten Schicht und ist daher nicht immer notwendig.Then another layer of epoxy resin is applied to the impact-resistant layer and solidified. This layer has a thickness between 0.05 and 0.13 mm, preferably 0.076 mm. she causes a seal of the possibly porous surface of the impact-resistant layer and is therefore not always necessary.
Nach einer anderen Ausführungsform der Erfindung enthält das Kunstharz einen Füllstoff von staubförmigem Aluminium oder einer pulverförmigen Aluminiumlegierung und wird ohne Aufbringung einer Schicht eines derartigen Pulvers verfestigt. Nach der Verfestigung wird die Oberfläche der Schicht aus Kunstharz durch Schrot oder Sandstrahl aufgerauht, um Partikeln des Füllstoffes aus Aluminium oder einer Aluminiumlegierung freizulegen. Danach wird der Überzug aus Aluminium oder einer Aluminiumlegierung auf die freigelegten Partikeln aufgespritzt. Im übrigen verläuft das Verfahren wie oben beschrieben. According to another embodiment of the invention, the synthetic resin contains a filler of powdery form Aluminum or a powdered aluminum alloy and is made without application solidified with a layer of such powder. After solidification, the surface of the layer is made Synthetic resin roughened by shot or sandblasting to remove particles of filler made of aluminum or a To expose aluminum alloy. Then the coating is made of aluminum or an aluminum alloy sprayed onto the exposed particles. Otherwise, the procedure is as described above.
Es hat sich gezeigt, daß die harte, durch die abriebfeste Schicht gebildete Oberfläche, auch wenn sie mit einem Kunstharz überzogen ist, den Abrieb des Propdllerblattes herabmindert. Gleichzeitig haftet die Schicht sogar bei hohen Rotationsgeschwindigkeiten sicher an dem Blatt, während sie zur Inspektion des Blattes durch Behandlung mit einem harzablösenden, für das Blatt unschädlichen Material wieder entfernbar gemacht werden kann.It has been shown that the hard surface formed by the abrasion-resistant layer, even if it is with is coated with a synthetic resin, the abrasion of the propeller blade diminishes. At the same time, the layer adheres even at high rotation speeds securely on the sheet while you are inspecting the sheet by treating it with a resin-releasing, material harmless to the sheet can be made removable again.
Vor der Aufbringung des Kunstharzes kann die Oberfläche des Blattes mit einer Ätzgrandierung geätzt werden.Before the synthetic resin is applied, the surface of the sheet can be etched with an etching border will.
In dieser Beschreibung ist der Ausdruck »Propellerblatt aus einer Aluminiumlegierung« so zu verstehen, daß er jedes Blatt aus einer Aluminiumlegierung einschließt, ob es eine Oxydoberfläche hat oder nicht. In den meisten Fällen werden die Propellerblätter aus einer Aluminiumlegierung vor der Vorbereitung auf die erfindungsgemäße Behandlung eloxiert.In this description, the expression "propeller blade made of an aluminum alloy" is to be understood as that it includes any sheet of aluminum alloy, whether it has an oxide surface or not. In most cases, the propeller blades will be made of an aluminum alloy before preparation anodized to the treatment according to the invention.
