Abstract

Ein Verfahren zum Ermitteln des Anteils zumindest eines Zuschlagstoffes eines Multikomponentenpulvers zum thermischen Spritzen weist folgende Schritte auf: Beleuchten des Pulverinjektionsstrahls vor dem Eintritt in den Heißgasstrahl; Erfassen der Fluoreszens des/der Zuschlagsstoffe(s); Auswerten der Fluoreszenserfassung mittels Emissionsspektroskopie. Ferner wird eine Vorrichtung zur Durchführung des Verfahrens angegeberi. Hierdurch werden die Nachteile des Standes der Technik vermieden und eine verbesserte prozesssichere Lösung zur Online-Prozesskontrolle beim thermischen Spritzen zur Verfügung gestellt, mit der eine selektive Detektierung und die quantitative Bestimmung von fluoreszierenden Zuschlagstoffen sichergestellt wird.

Figure imgaf001
A method for determining the proportion of at least one additive of a multicomponent powder for thermal spraying comprises the following steps: illuminating the powder injection jet before it enters the hot gas jet; Detecting the fluorescence of the additive (s); Evaluation of the fluorescence detection by means of emission spectroscopy. Furthermore, an apparatus for carrying out the method is angegebeni. This avoids the disadvantages of the prior art and provides an improved process-reliable solution for online process control in thermal spraying, which ensures selective detection and the quantitative determination of fluorescent additives.
