| 摘 要： | 以碳球为模板,采用水热法合成Gd-Yb-YSZ陶瓷粉,并用商业陶瓷粘接剂将合成的陶瓷粉涂覆在GH4169高温合金块表面,再经干燥和热处理制得热障涂层。制得的Gd-Yb-YSZ涂层抗热震循环次数为25次,粘接强度为32 MPa,比等离子体喷涂制得的YSZ涂层粘接强度高。等离子体喷涂得到的YSZ涂层平均厚度为270μm,自制Gd-Yb-YSZ涂层平均厚度仅68μm,但其隔热温度比YSZ涂层隔热温度高15℃。Gd-Yb-YSZ涂层主要物相为Yb0.5Zr0.5O1.75,Yb元素很可能掺入ZrO2晶体结构中,而Gd元素以单独的GdO2相存在。因此,Gd-Yb-YSZ涂层隔热能力的提高可能是Yb掺杂引起的。
