Abstract
Beschichtungen für Bauteile können nach dem Stand der Technik auf verschiedene Art und Weise hergestellt werden. Dabei müssen nicht nur bestimmte Anforderungen für bestimmte Einsatzbedingungen erfüllt werden, sondern auch die Herstellung muss schnell, einfach und kostengünstig sein. Die erfindungsgemäße Verwendung einer Sprühkompaktierungsanlage (1) zur Erzeugung einer Schicht (16, 19) ermöglicht dies, indem ein erfindungsgemäßes Schichtsystem (28) in bekannten Sprühkompaktierungsanlagen (1) eingebracht wird und dort beschichtet wird. <IMAGE>Coatings for components can be produced in various ways according to the prior art. Not only do certain requirements for certain operating conditions have to be met, but also the production has to be quick, easy and inexpensive. The use of a spray compacting system (1) according to the invention for producing a layer (16, 19) makes this possible by introducing a layer system (28) according to the invention in known spray compacting systems (1) and coating it there. <IMAGE>
