摘要： Alloys containing aluminium are characterised by an outstanding oxidation resistance at high temperatures, that is based on, inter alia, the formation of a thick and slow-growing aluminium oxide layer on material surfaces. If the formation of the aluminium oxide layer reduces the aluminium content of the alloy so far that a critical aluminium concentration is not reached, no other protective aluminium oxide layer can be formed. This leads disadvantageously to a very rapid breakaway oxidation, and the destruction of the component. This effect is stronger at temperatures above 800° C. due to the fact that, often at this point, metastable Al2O3 modifications, especially θ- or γ-Al2O3, are formed instead of α-Al2O3 that is generally formed at high temperatures. The above-mentioned oxide modifications are disadvantageously characterised by significantly higher growth rates. The invention relates to methods whereby aluminium-containing alloys advantageously form an oxidic covering layer predominantly consisting of α-Al2O3, at a temperature higher than 800° C., especially in the initial stage of oxidation, and thus have a significantly improved long-term behaviour.

摘要翻译： 含有铝的合金的特征在于在高温下具有突出的耐氧化性，这尤其是在材料表面上形成厚而缓慢生长的氧化铝层。 如果氧化铝层的形成降低了合金的铝含量，使得没有达到临界铝浓度，则不能形成其它保护性氧化铝层。 这导致非常快速的分离氧化和组分的破坏。 这种效应在高于800℃的温度下更强，因为通常在这一点上形成亚稳态Al 2 O 3改性，特别是α-Al 2 O 3，而不是通常在高温下形成的α-Al 2 O 3。 上述氧化物改性的不利特征在于显着较高的生长速率。 本发明涉及一种方法，其中含铝合金有利地在高于800℃的温度下形成主要由α-Al 2 O 3组成的氧化覆盖层，特别是在氧化的初始阶段，因此具有显着改善的长期 行为。

摘要： An interconnector is made of ferritic chromium steel, on which a cupriferous layer is disposed. This layer prevents interdiffusion between the chromium steel and additional components with which the interconnector has direct contact. According to the state of the art, such diffusion occurs particularly if these additional components contain nickel. In addition, the interconnector may comprise a chromium-containing oxide layer as a barrier against interdiffusion. For this purpose, the interconnector steel can also be preoxidized before applying the cupriferous layer. The interconnector has a significantly longer service life than interconnectors according to the state of the art, and it has improved electrical conductivity because the electrical contact surface thereof is free of oxides and has high transverse conductivity.

摘要： MCrAl layers according to prior art often display chipping of the thermally grown aluminum oxide layer (TGO) as a result of thermally induced stresses, which significantly reduces the oxidation behavior or the bonding behavior of ceramic heat insulating layers. An inventive MCrAl layer is designed in such a way that the TGO created thereon is microporous and thus allows expansion. The microporosity of the TGO is ensured by adding elements into the MCrAl layer in a targeted manner.
