Abstract

Adherent titanium coatings are applied to a substrate by a thermal spraying, using either the flame spraying or electric arc methods. The Ti is either in wire or powder form. The coating are used as a base for preparing titanium ceramics.

Description

Titel: Verfahren zur Herstellung von festhaftenden AuftragungenTitle: Process for the production of firmly adhering applications

im thermischen Spritzverfahren mit dem Spritzwerkstoff Titan ausgeführt. Executed in the thermal spray process with the spray material titanium.

Beschreibung: Gegenstand der Erfindung ist ein Verfahren bei dem über dem Ausgangs-Spritzwerkstoff Titan eine Titan-Ceramik aufgetragen und so nutzbar gemacht wird.Description: The invention relates to a method in which over A titanium ceramic is applied to the initial spray material titanium and can thus be used is made.

Bekannt ist aus Veröffentlichungen, daß Titan als Spritzwerkstoff unter konventionellen Betriebsbedingungen unbrauchbar ist, das geht auch aus dem österreichsichen Patent Nr.215 247 hervor. It is known from publications that titanium is used as a spray material is unusable under conventional operating conditions, that is also possible from the Austrian patent number 215 247.

Nach einem USA-Patent wird Molybdän als Haftschicht für andersartige Metalle als Folgeauftragung verwendet. According to a US patent, molybdenum is used as an adhesive layer for other types of material Metals used as a follow-up order.

Auf Buntmetall versagt jedoch Molybdan vollkommen, es werden keine Vorteile gegenüber irgend einer anderen Auftragung erreicht. On non-ferrous metal, however, molybdenum fails completely, it won't Advantages over any other application achieved.

Titan-Ceramik hat dagegen die Eigenschaft auch auf Buntmetall eine festhaftende Einbrennlage zu bewirken. Sowohl beim Molybdän als auch beim Titan entsteht wahrend der Schmelzvorganges eine starke exotherme Reaktion, die zur Temperatursteigerung führt. Titanium ceramics, on the other hand, also have the same properties on non-ferrous metals to bring about a firmly adhering stoving layer. Both with molybdenum and with titanium A strong exothermic reaction occurs during the melting process, which increases the temperature leads.

Auf diese Reaktion beruht der Einbrenneffekt dieser beiden Metalle, der jedoch bei Molybdän zum Einbrennen in Buntmetalle nicht ausreicht. Sobald Titan zum Schmelzfluß im Lichtbogen oder in der Autogenflamme gebracht wird, zerfällt es in Titan-Oxyd, -Nitrid, -Hydrid und -Carbid. Dieses Produkt ist Titan-Ceramik und erfindungsgemäß für das thermische Spritzverfahren brauchbar. The burn-in effect of these two metals is based on this reaction, However, in the case of molybdenum, this is not sufficient to burn into non-ferrous metals. Once titanium is brought to the melt flow in the arc or in the oxy-fuel flame, disintegrates it in titanium oxide, nitride, hydride and carbide. This product is titanium ceramic and usable according to the invention for the thermal spray process.

Titan-Ceramik kann als Spritzwerkstoff für alle denkbaren Substrate als Haftgrund Verwendung finden. Reine Titanauftragungen sind im thermischen Spritzverfahren verarbeitet, als solche nur möglich, wenn sie unter Inertgas (Formiergas) zum Beispiel in Kammern verspritzt werden, das soll jedoch nicht angestrebt werden. Ein mit Titan-Ceramik beschichtetes Buntmetall-Substrat kann nur durch Zerstörung des Substrates getrennt werden. Titanium ceramic can be used as a spray material for all conceivable substrates can be used as a primer. Pure titanium applications are in the thermal spray process processed as such only possible when under inert gas (forming gas) for example be sprayed in chambers, but this is not the aim. One with titanium ceramics Coated non-ferrous metal substrate can only be separated by destroying the substrate will.

Die zur Zeit bekannten Metallkleber reichen nicht aus um den intensiven Haftwert bestimmen zu konnen. Eine Einbrennlage in der Stärke von o.o5 mm reicht vollkommen aus, um einen ausreichenden Haftgrund für nachfolgende andere Beschichtungen zu erhalten. Es ist kein Problem auch Starkauftragungen mit Titan-Ceramik durchzuführen.The currently known metal adhesives are not sufficient for the intensive one To be able to determine the adhesion value. A burn-in layer with a thickness of o.o5 mm is sufficient to create a sufficient primer for subsequent other coatings to obtain. It is not a problem to also apply heavy build-ups with Titan-Ceramik.

Dort wo eine Molybdan-Beschichtung versagt, bietet eine Titan-Ceramik-Beschichtung eine Einbrennlage als Haftgrund. Die gleiche Basis wie eine Beschichtung mit Molybdan nimmt auch Titan-Ceramik ein, nur mit dem Unterschied, daß auch Buntmetalle durch letztere einen Einbrenneffekt erreichen lassen.Where a molybdenum coating fails, a titanium-ceramic coating offers a burn-in layer as a primer. The same base as a coating with molybdenum also uses titanium ceramics, the only difference being that non-ferrous metals also come through let the latter achieve a burn-in effect.

Es ist dabei gleichgültig, ob die Beschichtung im Flamm-oder Lichtbogenspritzverfahren ausgeführt wird, der Zerfall des Titans in Titan-Ceramik findet in beiden Fällen statt und soll zur Haftverbesserung Anwendung finden.It does not matter whether the coating is flame or arc sprayed is carried out, the disintegration of the titanium in titanium ceramics takes place in both cases instead and should be used to improve adhesion.

Obwohl in Veröffentlichungen die Unbrauchbarkeit der Titan-Verarbeitung im Flamm- oder Lichtbogenspritzverfahren beschrieben wird, hat sich der Anmelder mit jahrelangen Forschungsarbeiten auf diesem Gebiete mit der Brauchbarkeit für diese Verfahrenstechnik befaßt.Although in publications the uselessness of titanium processing is described in the flame or arc spray process, the applicant has with years of research in this area with usefulness for this process engineering is concerned.

Die starke Affinitat und die damit zusammenhängende exotherme Reaktion, welche zum Zerfall zu Titan-Ceramik führen, sind Basis der Nutzanwendung für das thermische Spritzverfahren. Titan kann doch unter konventionalen Voraussetzungen für das thermische Spritzverfahren eingesetzt werden. Der Anmeldungsgegenstand bringt daher etwa Neues von patentbegründender Bedeutung.The strong affinity and the related exothermic reaction, which lead to the disintegration of titanium-ceramics, are the basis of the useful application for the thermal spray process. Titan can under conventional conditions can be used for thermal spraying. The subject of the registration brings hence something new that is of importance to establish a patent.
