摘要:

采用固相法合成SrZrO₃粉末并对合成的粉末进行喷雾造粒,采用大气等离子喷涂 (APS) 制备SrZrO₃热障涂层 (TBCs)。将合成的SrZrO₃粉末与CaO-MgO-Al₂O₃-SiO₂ (CMAS) 粉末混合,以及在等离子喷涂SrZrO₃涂层表面涂覆CMAS粉末,分别在1150和1250 ℃进行腐蚀行为研究,分别使用XRD和SEM对腐蚀产物相和涂层显微结构进行表征。结果表明：在1150 ℃下,SrZrO₃粉末不与CMAS发生腐蚀反应;当温度升高到1250 ℃时,两者发生反应,腐蚀1 h后生成ZrSiO₄,CaZrO₃,SrAl₂O₄和t-ZrO₂,而腐蚀4 h后出现新相m-ZrO₂。在1250 ℃下,随着腐蚀时间增长,反应生成的t-ZrO₂转变为m-ZrO₂,此时的腐蚀产物层可抑制CMAS的进一步腐蚀。

Abstract：

SrZrO₃ powders were synthesized by solid-state reaction and then spray granulation. The SrZrO₃ coating on superalloy In718 was prepared by air plasma spray (APS). The corrosion behavior of the SrZrO₃ coated alloy beneath a thin deposit of CMAS (CaO-MgO-Al₂O₃-SiO₂) was examined in air at 1150 and 1250 ^oC for 1, 4 and 12 h respectively, while the reaction of powder mixture of SrZrO₃ and CMAS was investigated paralell. The corrosion products of SrZrO₃ powders and the microstructure of SrZrO₃ coating after corrosion were characterized by XRD and SEM, respectively. The reaction between the two powders of SrZrO₃ and CMAS did not occur at 1150 ^oC, whereas occurred at 1250 ^oC for 1 h, which resulted in the formation of corrosion products of ZrSiO₄, CaZrO₃, SrAl₂O₄ and t-ZrO₂, and then a new phase of m-ZrO₂ did additionally appear for 4 h corrosion. The corrosion product of t-ZrO₂ was formed on the SrZrO₃ coating surface after CMAS attack, and the phase transition from t-ZrO₂ to m-ZrO₂ occurred as the corrosion time increased, the formation of the corrosion products could suppress the further corrosion of the SrZrO₃ coating by CMAS.
