Title
(DE) SCHUTZSCHICHT GEGEN UMWELTEINFLÜSSE (UMWELTBARRIERESCHICHT) FÜR Ti-Al MATERIAL
(EN) PROTECTIVE LAYER AGAINST ENVIRONMENTAL INFLUENCES (ENVIRONMENTAL BARRIER LAYER) FOR TI-AL MATERIAL
(FR) COUCHE DE PROTECTION CONTRE LES INFLUENCES ENVIRONNEMENTALES (COUCHE BARRIÈRE ENVIRONNEMENTALE) POUR MATÉRIAU TI-AL
Abstract
(DE) Die vorliegende Erfindung betrifft eine Oberflächenbeschichtung zum Schutz von Substraten mit Ti-Al Material, vorzugsweise umfassend eines oder mehrerer der Materialien aus Tabelle 1, wobei die Beschichtung eine Schichtfolge mit mindestens einer Schicht umfasst, die für Ti eine Diffusionsbarriere bildet, vorzugsweise entsprechend einer oder mehrerer der in Tabelle 1 in Zeilen angegebenen Schichtfolgen, und wobei die Beschichtung eine, insbesondere auf die Diffusionsbarriere abgestimmte, Oxidationsbarriere umfasst, die vorzugsweise entsprechend Tabelle 2 abgestimmt ist, und insbesondere wobei die Oberflächenbeschichtung eine thermische Barriere umfasst, die vorzugsweise entsprechend Tabelle 3 auf die Oxidationsbarriere abgestimmt ist.
(EN) The present invention relates to a surface coating for protection of substrates comprising Ti-Al material, preferably comprising one or more of the materials from table 1, wherein the coating comprises a layer sequence having at least one layer that forms a diffusion barrier for Ti, preferably in accordance with one or more of the layer sequences specified in lines in table 1, and wherein the coating comprises an oxidation barrier, especially one matched to the diffusion barrier, preferably in accordance with table 2, and especially wherein the surface coating comprises a thermal barrier which is preferably matched to the oxidation barrier in accordance with table 3.
(FR) La présente invention concerne un revêtement de surface pour la protection de substrats comprenant un matériau Ti-Al, comprenant de préférence un ou plusieurs des matériaux du tableau 1, le revêtement comprenant une séquence de couches comportant au moins une couche qui forme une barrière de diffusion pour Ti, de préférence conformément à une ou plusieurs des séquences de couches spécifiées dans les lignes du tableau 1, et le revêtement comprenant une barrière d’oxydation, en particulier correspondant à la barrière de diffusion, de préférence conformément au tableau 2, et en particulier le revêtement de surface comprenant une barrière thermique qui est de préférence adaptée à la barrière d’oxydation conformément au tableau 3.
