Abstract (en)
[origin: EP2006409A2] The method involves illuminating a powder injection jet (6) before entering into a hot gas jet (7), and detecting the fluorescence of a polyester additive by detection optics, where the additive is provided with multiple fluorescence markers. The powder injection jet is illuminated by a coherent light source such as laser light source. The detection optics is formed as a fiber-optic cable. The detected fluorescence is evaluated by utilizing emission spectroscopy. Independent claims are also included for the following: (1) a method for online-process control during thermal spraying (2) a device for selective detection of an additive during thermal spraying.
