Abstract
A device, a method for marking a substrate (14) with a plasma generator (5) and a corresponding marking are disclosed. A plasma jet (11) is directed onto the substrate (14) and is superimposed with a powder jet (12). In a powder dosing and dispersing unit (7), a powder (20) and a marker substance (30) in powder form are mixed. The marking forms an adhesive layer (15) of the powder (20) material in which a marker substance (30) is homogeneously distributed and permanently embedded.
Claims16
A device for marking a substrate comprising:
- a plasma generator for generating a plasma jet which is directed onto the substrate;
- at least one first container containing powder and at least one second container containing a marker substance in powder form;
- a powder injector for generating a powder jet is arranged relative to the plasma generator such that the plasma jet and the powder jet are superimposed, such that a layer is formable on the substrate, wherein the powder jet is composed of the powder (20) and of the marker substance in powder form;
- and,
- a pulsed arc discharge is furnished by the plasma generator.
A method for marking a substrate comprising the steps:
- extracting a powder and a marker substance in powder form from at least one first container or extracting a powder from at least one first container and a marker substance in powder form from at least a second container;
- generating a powder jet from a homogeneous dispersion of the powder and the marker substance in powder form;
- generating a plasma jet with a plasma generator;
- inserting the powder jet into the plasma jet;
- and,
- superimposing the powder jet and the plasma jet.
A marking for a substrate, comprising:
- a layer adhesively secured to the substrate formed by a thermal spraying process, wherein the layer is a powder mixture of a powder and a marker substance, wherein the powder forms a matrix in which the marker substance is homogeneously distributed and permanently embedded.
A device for marking a substrate comprising:
- a plasma generator for generating a plasma jet which is directed onto the substrate;
