Ein derartiges Auftragungsverfahren hat sich als besonders wirtschaftlich erwiesen.In particular, the component has at least one sprayed-on metal or ceramic powder collar. Such an application method has proven to be special economically proven.
Ein Pulverkragen mit endlicher Dicke stößt gewöhnlich an den äußeren Umfang eines benachbarten Bauteil an bestimmter Stelle an, um einen Abstand zwischen den einzelnen Bauteilen einzurichten. Die Auftragungsschicht des metallenen oder keramischen Pulverkragens kann vergleichsweise dünn sein, wenn in vorteilhafter Weiterbildung der Erfindung benachbarte Bauteile Metall- oder Keramikpulverkragen in gleicher Höhe bzw. Lage besitzen und die Pulverkragen benachbarter Bauteile sich einander berühren. Dacurc;t lassen sich benach-Warte Bauteile nicht nur auf Abstand halten und sich gegenseitig fixieren, sondern es berühren sich im zusammenzesetzten Zustand der Anordnung lediglich die einzelnen Pulvertragen 1 die im getrieb (beispielsweise be-' Temperaturunterschieden' einer Relativbewegung ausgesetzt sein können. Die Pulverkragen unterliegen keiner Reibkorrosion.A powder collar of finite thickness usually abuts the outer one Circumference of an adjacent component at a certain point to allow a distance between to set up the individual components. The application layer of the metal or ceramic powder collar can be comparatively thin, if more advantageous Further development of the invention adjacent components metal or ceramic powder collar have the same height or position and the powder collars of adjacent components touch each other. Because of this, components can not only be adjoined at a distance hold and fix each other, but touch each other in the composite State of the arrangement only the individual powder trays 1 in the gear (for example Be 'temperature differences' can be exposed to a relative movement. the Powder collars are not subject to fretting corrosion.
Be Bauteilen, die im Betrieb sehr hohen Temperaturen ausgesetzt sind, welche zur Ausdehnung oder Schrumpfung führen, verwendet man bevorzugt eine Netall- oder Keramikpulverschicht aus dem Material des bauteils selbst.For components that are exposed to very high temperatures during operation, which lead to expansion or shrinkage, it is preferable to use a metal or ceramic powder layer made from the material of the component itself.
Die Bauteile sind bei einem Wärmetauscher zweckmäßigerweise zueinander ausgerichtete U-förmige Lanzettenröhrchen, wobei das gesamte Lanzettenröhrchen-Parket bevorzugt von einem äußeren Halterahmen umschlossen ist, dessen Innenumfang mit einer Metall- oder heramikschicht nach Art der Pulverkragen selbst beschichtet ist.In a heat exchanger, the components are expediently relative to one another aligned U-shaped lancet tubes, with the entire lancet tube parket is preferably enclosed by an outer holding frame, the inner circumference with a metal or ceramic layer is coated in the manner of the powder collar itself.
Besonderer Vorteil der Erfindung ist, daß man durch gezielten Spritzpulverauftrag die Eigen frequenz der Bauteile beeinflussen und damit Schwingungsbrüche vermeiden kann.A particular advantage of the invention is that by targeted spray powder application influence the natural frequency of the components and thus avoid vibration breaks can.
Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels unter Bezugnahme auf die Zeichnung näher erläutert; es zeigen: Fig. 1 ein Bauteil in Form eines Kühlröhrchens einer Wärmetauscheranordnung in einer schematischen Seiten an sicht, und Figuren 2 und 3 einen äußeren zweigeteilten halterahmen in einer perspektivischen Ansicht.The invention is described below using an exemplary embodiment Referring to the drawing explained in more detail; They show: FIG. 1 a component in form a cooling tube of a heat exchanger arrangement in a schematic page view, and Figures 2 and 3 an outer two-part holding frame in a perspective Opinion.
