Hollow yttrium oxide partially-stabilized zirconium oxide powder as well as preparation method and application thereof
The invention discloses hollow yttrium oxide partially-stabilized zirconium oxide powder as well as a preparation method and application thereof. The powder has a thin-shell hollow structure, the shell thickness is 5-10 microns, and the hollow rate is 50-60%. The powder can be fused and deposited in low-power plasma spraying, the obtained coating has partial spherical pores and high porosity, the heat conductivity of the coating can be effectively reduced, and meanwhile, the bonding strength and thermal shock resistance of the coating reach the same level of a nano 8YSZ spraying coating.
本发明公开了一种中空氧化钇部分稳定氧化锆粉体、制备方法及其用途，所述粉体具有薄壳中空结构，壳体厚度为5～10μm，中空率为50～60％。该粉体可以在较低功率等离子喷涂中熔融沉积，获得的涂层具有部分球形孔隙及高的孔隙率，能够有效降低涂层的热导率，同时涂层的结合强度及抗热震性能达到纳米8YSZ喷涂涂层相等水平。
