摘要

The LaMgAl₁₁O₁₉ was prepared by air plasma spraying technology to investigate the corrosion behavior of 38CaO-5MgO-8AlO_1.5 -49SiO₂ (CMAS) at high temperature. The microstructure, element distribution and phase composition of LaMgAl₁₁O₁₉ coating before and after CMAS corrosion at 1050 and 1250 ℃ were investigated by SEM, EDS and XRD. The results show that CaAl₂Si₂O₈ and MgAl₂O₄ can be observed in LaMgAl₁₁O₁₉ coating after corroded at 1250 ℃ for 24 h. Besides, according to the thickness of corroded zone in LaMgAl₁₁O₁₉ coating, the apparent activation energy in the temperature range of 1050~1250 ℃ is 94.1 kJ/mol.
