METHOD FOR PRODUCING GAS-TIGHT LAYERS AND LAYER SYSTEMS BY MEANS OF THERMAL SPRAYING

The invention relates to a method for producing gas-tight layers and layer systems by means of a thermal spraying method. A layer is firstly applied by thermal spraying using a burner and is subjected to a subsequent thermal treatment by the same burner. This interruption-free method makes possible...

Zusammenfassung:	The invention relates to a method for producing gas-tight layers and layer systems by means of a thermal spraying method. A layer is firstly applied by thermal spraying using a burner and is subjected to a subsequent thermal treatment by the same burner. This interruption-free method makes possible a simple and cost-effective production of gas-tight layers and layer systems having good adhesive properties. The method is particularly suited for producing fuel cell structures due to the fact that a gas-tight layer can be placed at any location in a layer system.
