摘要： 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.

摘要： The aim of the invention is to produce complete high temperature fuel cells by means of thermal injection processes (e.g. atmospheric plasma injection, vacuum plasma injection, high speed flame injection). The production method is especially simplified and is economical by virtue of the fact that the carrier substrate is also produced on a base with the aid of a thermal injection method. The base or an intermediate layer placed thereon can be advantageously dissolved or decomposed such that the carrier substrate provided with layers arranged thereon can be separated in a very simple manner from the base which becomes unnecessary. Said method advantageously enables the production of all layers of a high temperature fuel cell, exclusively with the aid of a thermal injection method.

摘要： The invention relates to a method for producing a tight crystalline mullite layer on a metallic and/or ceramic substrate by using the plasma spraying technique. To this end, a sol containing mullite precursors with a proportion of 2 to 25 % by weight with regard to the oxides (3 Al 2 O 3 /2 SiO 2 ) is used as a spraying additive. This method is carried out under atmospheric conditions, and the sol is injected with a focussed jet and with an overpressure of at least one 1 bar into the plasma flame. An additional compacting of the layer can be advantageously effected by repeatedly passing over the layer with the plasma flame. The method is particularly suited for applying a gas-tight crystalline mullite layer to a steel substrate.

摘要： The invention relates to a method for coating a substrate with a powder by means of a thermal spraying process, in which the powder is introduced into a plasma jet and is applied to the substrate with the aid of the plasma. According to the invention, at least some of the powder that diverges from the plasma jet is deflected from the substrate and/or redirected into the plasma jet by a means. A device that is suitable for carrying out the inventive method and deflects and/or focuses a portion of a powder jet comprises a means for deflecting and/or focusing particles, which has the shape of a hollow cylinder and contains graphite and/or high-grade steel. Said means has a minimum inner diameter ranging between 5 and 30 mm, particularly between 10 and 20 mm, and a length of 5 to 80 mm, especially 10 to 50 mm. The inner and/or outer surface of the means is provided with a surface geometry which is curved in such a way that said means is able to deflect and/or focus powder particles diverging from an introduced powder jet.
