. Dans-le, Aucune zone d'attaque n'a été repérée sur le creuset présentant une couche de MC en surface, de plus la goutte de bismuth et le creuset n'étaient pas solidaires après refroidissement. La structure MC est donc protectrice vis-à-vis du bismuth liquide. A l'inverse, l'adhérence entre les creusets et la goutte de bismuth a été constatée pour les trois autres structures de surface. De plus, quelques piqûres d'attaque ont été repérées mais

, sels CaCl2 liquides, la dégradation des creusets est limitée quelle que soit la microstructure de surface, aucune zone d'attaque n'a été repérée sur l'ensemble des creusets. L'ensemble des microstructures de surface présentaient une adhérence avec la goutte de sels solidifiée sauf la structure MC pour laquelle la goutte et le creuset n'étaient pas solidaires. La structure MC semble donc avantageuse pour l'utilisation des sels CaCl2 liquides
