Title (DE) TIEGEL
(EN) CRUCIBLE
(FR) CREUSET
Abstract:
(DE) Tiegel (1) mit einer Wandung (3) aus einem Grundwerkstoff aus Wolfram oder Molybdän oder aus einem auf Wolfram oder Molybdän basierenden Werkstoff, dadurch gekennzeichnet, dass an einer Außenseite (6) der Wandung (3) und/oder in der Wandung (3) zumindest abschnittsweise eine Sperrschicht (2) aus einem metallischen Werkstoff mit höherer Affinität gegenüber Kohlenstoff und/oder Sauerstoff als der Grundwerkstoff ausgebildet ist.
(EN) The invention relates to a crucible (1) having a wall (3) which is made of a base material of tungsten or molybdenum or of a tungsten-based or molybdenum-based material, characterized in that a barrier layer (2) from a metallic material with a higher affinity to carbon and/or oxygen than the base material is formed at least in sections on an outer side (6) of the wall (3) and/or in the wall (3).
(FR) Creuset (1) présentant une paroi (3) réalisée dans un matériau de base constitué de tungstène ou de molybdène ou dans un matériau à base de tungstène ou molybdène, caractérisé en ce qu'une couche barrière (2) constituée d'un matériau métallique présentant, par rapport au matériau de base, une affinité supérieure vis-à-vis du carbone et/ou de l'oxygène est formée, au moins dans certaines zones, sur une face extérieure (6) de la paroi (3) et/ou dans la paroi (3).
