METHOD FOR COATING BY THERMAL SPRAYING WITH AN INCLINED PARTICLE JET

The invention relates to a method for coating a substrate (11) by thermal spraying, in particular cold-gas spraying. Here, a particle jet (13) is oriented at an inclination to the surface (14) of the substrate (11) to form a spraying angle (a). In order to increase the possible spraying angle (a) ac...

Beschreibung
Zusammenfassung:	The invention relates to a method for coating a substrate (11) by thermal spraying, in particular cold-gas spraying. Here, a particle jet (13) is oriented at an inclination to the surface (14) of the substrate (11) to form a spraying angle (a). In order to increase the possible spraying angle (a) according to the invention, it is provided that the surface (14) is applied with a directional patterning, for example comprising trenches (17) and ridges (18). The orientation of this patterning is inclined by an angle of inclination (ß), specifically in the direction of the spraying angle (a). As a result, the adhesion of striking particles (12) is improved and it is possible to achieve larger spraying angles (a).
