METHOD FOR COATING BY THERMAL SPRAYING WITH AN INCLINED PARTICLE JET

A substrate is coated by cold-gas spraying in which a particle jet is oriented at an inclination to the surface of a substrate thus forming a spraying angle. To increase the possible spraying angle compared to the known art, the surface is applied with a directional patterning, for example trenches...

Beschreibung
Zusammenfassung:	A substrate is coated by cold-gas spraying in which a particle jet is oriented at an inclination to the surface of a substrate thus forming a spraying angle. To increase the possible spraying angle compared to the known art, the surface is applied with a directional patterning, for example trenches and ridges. The orientation of this patterning has an angle of inclination in the direction of the spraying angle. As a result, the adhesion of striking particles is improved and it is possible to achieve larger spraying angles.
