Preparation method and material of high-melting-point and long-service-life environmental barrier coating bonding layer
The invention discloses a preparation method and material of a high-melting-point and long-service-life environmental barrier coating bonding layer, the environmental barrier bonding layer is of a double-phase structure, that is, nearly spherical RESiO is discretely distributed in a continuous and compact RESi-based phase, and rare earth element doping is multi-element doping. The doping of the rare earth elements of the base phase increases the melting point and increases the temperature resistance of the base phase, the existence of the second phase can oxidize the base phase and then react with the base phase, SiO2 is eliminated, the aggregation of the low-melting-point phase and the generation of thermally generated oxides are avoided, and the high-melting-point, phase-change-free and long-life service of the novel bonding layer is realized.
本发明公开了一种高熔点、长寿命环境障涂层粘接层的制备方法及材料，该环境障粘结层为双相结构，即近球形RESiO离散分布在连续致密的RESi基相中，而且稀土元素掺杂为多元素掺杂。基相稀土元素的掺杂提升了其熔点，增加了其耐温性，第二相的存在能够使基相发生氧化后与之反应，消除SiO2，避免低熔点相的聚集和热生成氧化物的产生，实现了新型粘结层的高熔点、无相变和长寿命服役。
