Abstract: front page image
(DE)Bekannte Schutzschichten mit hohem Cr-Gehalt und zusätzlich Silizium bilden Sprödphasen aus, die unter dem Einfluss von Kohlenstoff während des Einsatzes zusätzlich verspröden. Die erfindungsgemässe Schutzschicht hat die Zusammensetzung 24% bis 26% Kobalt (Co), 10% bis 12% Aluminium (AI), 0,2% bis 0,5% Yttrium (Y), 12% - 14% Chrom (Cr), 0.3% - 5.0% Tantal (Ta), Nickel (Ni).
(EN)Known protective layers with a high Cr content and in addition silicon form brittle phases which additionally embrittle during use under the influence of carbon. The protective layer according to the invention has the composition of from 24% to 26% cobalt (Co), from 10% to 12% aluminium (Al), from 0.2% to 0.5% yttrium (Y), from 12% to 14% chromium (Cr), from 0.3% to 5.0% tantalum (Ta), nickel (Ni).
(FR)Les couches protectrices connues, présentant une teneur élevée en Cr ainsi que du silicium, forment des phases fragiles qui, pendant l'utilisation, se fragilisent davantage sous l'effet du carbone. La couche protectrice selon l'invention présente la composition suivante : 24% à 26% de cobalt (Co), 10% à 12% d'aluminium (AI), 0,2% à 0,5% d'yttrium (Y), 12% - 14% de chrome (Cr), 0,3% - 5,0% de tantale, le reste étant constitué de nickel.
