摘要：

The calcium magnesium aluminosilicate (CMAS) attack is becoming a critical obstacle to the application of thermal barrier coatings (TBCs). In this work, we prove that Ca2La8(SiO4)(6)O-2 is an effective TBCs material for resisting CMAS attack, and investigates its CMAS corrosion behaviors. The results indicate that no evidence of chemical reactions was found between CMAS and Ca2La8(SiO4)(6)O-2 heat-treated at 1300 ? and 1500 ?. The corrosion of apatite by CMAS occurs via dissolution and re-precipitation processes. At 1300 ?, the apatite Ca2La8(SiO4)(6)O-2 substrates have little evidence of damage. Moreover, the apatite can also effectively block the infiltration of CMAS up to 1500 ?.
