摘要： The invention relates to a electrically conductive steel-ceramic connection comprising a steel interconnector and an electrically conductive ceramic joining layer arranged thereon. The interconnector comprises a ferritic steel containing Cr in a quantity ranging from 18 to 24% by weight. The ceramic layer contains perovskite of a formula Ln1-xSrxMn1-yCoyO3-δ or Ln1-xSrxFe1-yCoyO3-δ, wherein 0.1≦x≦0.4, 0.1≦y≦0.6, 0≦δ≦x/2 and Ln=La—Lu. The inventive steel-ceramic connection is usable for a high-temperature fuel cell and regularly exhibits good adhesive properties and a low transition resistance (initial transition resistance R approximately equal to 0.01 Ωcm2). Said steel-ceramic connection makes it possible to advantageously introduce a ferritic steel into high-temperature fuel cells. The inventive method for producing said steel-ceramic connection consists in pre-treating an inserted ceramic powder exhibiting good sinterability during an assembly process and during the fuel cell operation.

摘要： The invention relates to the hardening of the surface layer of parts of machines, plants and apparatuses and also tools. Objects for which the application is possible and advantageous are components which are subjected to severe fatigue or wear stresses and are composed of hardenable steels and have a complicated shape and whose surface has to be hardened selectively on the functional surfaces or whose functional surface has a multidimensional shape. The process for hardening the surface layer of components having a complicated shape is carried out by means of a plurality of energy input zones. According to the invention, it is characterized in that the energy input zones are conducted on different curved parts separately in space and time and by means of cooperatively working transport systems so that superposition of the individual temperature fields forms a uniform temperature field which completely covers the functional surface of the component and within which each surface element of the later hardening zone of the component attains the selected austenite formation temperature interval ΔTa at least once and the time interval Δt between the maximum temperatures Tmaxn of the individual temperature fields is from 3.1 to 3.n smaller than the time ΔtmS which is required to go below the martensite start temperature MS during the cooling phase. The apparatus by means of which the process of the invention can be carried out is, according to the invention, characterized in that the energy configuring units are connected to one or more energy sources for optical or electromagnetic radiation and are each fixed to separate but cooperatively operating transport systems.

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.
摘要翻译：本发明的目的是通过热注射法（例如大气等离子体注入，真空等离子体注入，高速火焰喷射）来生产完整的高温燃料电池。借助于热喷射方法，也可以在基底上制造载体基板，因此制造方法特别简化，并且是经济的。放置在其上的基底或中间层可以有利地溶解或分解，使得设置有其上的层的载体基底可以以非常简单的方式与基底分离，这是不必要的。所述方法有利地使得能够专门借助于热注射方法来生产高温燃料电池的所有层。
