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 Al2O3/2 SiO2) 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 I 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 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 heat-insulating material, which is phase-stable particularly for high temperatures above 1150° C., especially above 1200° C., and which has a very good long-time stability. The heat-insulating material can exist in a number of phases of which at least one has the magnetoplumbite structure and stoichiometrically contains 0.1 to 10 mol % M12O3, 0.1 to 10 mol % Li2O and, as the remaining, M22O3 with incidental impurities. M1 is selected from the following elements: lanthanum, neodymium and gadolinium or mixtures thereof, and M2 is selected from the following elements: aluminum, gallium, iron or a mixture thereof. A particularly advantageous composition arises for this phase with the composition LaLiAl11O18.5 or LaLi0.5Al11.5O19. By using conventional methods, the heat-insulating material can be applied to the components subjected to a high level of thermal stress, for example, turbine blades. It is suited as a heat-insulating layer alone as well as for use in a composite material together with YSZ. The segmentation cracks regularly occurring in this heat-insulating material contribute significantly to a reduction in stresses between the heat-insulating layer and the coated component in the event of frequent alternating stresses.

摘要： The following steps are performed for joining workpieces of metal or ceramic to each other by boundary surface diffusion at the junction location. After laying together the surfaces at which the workpieces are to be joined together, a layer is applied to the outer edge of the joint location consisting of a material compatible with the material of the parts to be joined and mechanically stable under high static pressure. The layer is fixed and sealed. Thereafter the workpieces are diffusion welded by hot isostatic pressing (HIP). A layer meeting the requirements of this process can be applied by plasma spraying onto the region of the seam at the outer edge of the junction location.

摘要： The invention relates to a method for producing highly porous, metallic moulded bodies. The inventive method consists of the following steps: a metallic powder used as a starting material is mixed with a dummy; a green body is pressed out of the mixture; the green body is subjected to conventional mechanical machining, the dummy advantageously increasing the stability of the green body; the dummy material is thermally separated from the green body by means of air, a vacuum or an inert gas; and the green body is sintered to form the moulded body and is then advantageously finished. Suitable materials for the dummy are, for example, ammonium bicarbonate or carbamide. The mechanical machining carried out before the sintering advantageously enables a simple production close to the desired final contours, even for complicated geometries of the moulded body to be produced, without impairing the porosity, and without high wear of the tools. The workpiece is advantageously sufficiently stable in terms of pressure for the green machining as the dummy material is still present in the pores of the green body during the machining.

摘要： The invention relates to a method for the hydrothermal production of a microporous membrane. According to said method, a colloidal solution comprising zeolite frameworks with 4-ring, 6-ring, and/or 8-ring pores which are provided as crystallites whose size ranges from 2 to 25 nm is applied to a porous substrate with the aid of a wet application technique. The applied layer is contacted with a hydrothermal liquid, and a nanocrystalline, microporous zeolite layer having an average pore diameter of 0.2 to 0.45 nm is synthesized at temperatures ranging between 50 and 250° C. and at an autogenous pressure. Such a microporous membrane comprising a porous substrate and at least one nanocrystalline zeolite layer that is disposed thereupon and has an average pore diameter of 0.2 to 0.45 nm is advantageously suitable for use as a separating device for gas phase separation, making it possible to separate particularly N2O2, N2/CO2, H2/CO2, or CO2/CH4 gas mixtures. Said separating device is especially temperature-resistant and can therefore be integrated directly into thermal processes.

摘要： Disclosed is a modified powder injection molding method which is advantageously used for producing highly porous, near net-shaped parts having complex geometries from initial metallic and/or ceramic powders. The placeholders that are used are non-toxic and can be quickly and almost entirely removed from the parts. Said placeholders make it possible to specifically adjust the pore sizes of the parts within a range of 20 ?m to 2 mm and the porosities thereof within a range of 10 to 85 percent by volume, the distribution of pores being very homogeneous. The duration of the entire process is determined to a considerable degree by the removal of the binder and the placeholders. The total time required from the step of preliminary surface-active binder removal is no more than 14 to 20 hours, even if preliminary thermal binder removal is added (for metal powders and ceramic powders
