Chemical Stability between NiCr(2)O(4) Material and Molten Calcium-Magnesium-Alumino-Silicate (CMAS) at High Temperature

NiCr(2)O(4) as a potential protection for thermal barrier coatings (TBCs) against the attack of molten calcium-magnesium-alumino-silicate (CMAS) was studied by a CMAS-contacting experiment. Atmospheric plasma sprayed coatings and sintered bulk materials were fabricated, covered with CMAS deposits, a...

description NiCr(2)O(4) as a potential protection for thermal barrier coatings (TBCs) against the attack of molten calcium-magnesium-alumino-silicate (CMAS) was studied by a CMAS-contacting experiment. Atmospheric plasma sprayed coatings and sintered bulk materials were fabricated, covered with CMAS deposits, and exposed to 1200 °C for 24 h. Nano-sized CMAS-NiCr(2)O(4) mixed powder was manufactured by ball milling and then conducted heat treatment under the same condition. The results show that no reacting product was found at the border between molten CMAS and NiCr(2)O(4) and no element transportation occurred. It can be inferred that NiCr(2)O(4) has outstanding chemical stability with the molten CMAS.
