2O3 partially stabilized ZrO2）基團(tuán)聚顆粒，對4種團(tuán)聚顆粒的流動性、松裝密度及粒徑分布進(jìn)行了研究。利用等離子噴涂技術(shù)制備了上述4組高溫封嚴(yán)涂層，測量了各組粉末的沉積效率，分析了不同粘接相的粘接機(jī)理。結(jié)果表明，與B0型團(tuán)聚粉末相比，B1、B2和B3型團(tuán)聚粉末的流動性分別降低了6.94%、5.15%和25.2%，松裝密度分別減少了2.85%、2.19%和7.67%，大粒度的團(tuán)聚粉末所占比例分別提高了15.82%、6.65%和29.75%；B1、B2和B3型團(tuán)聚粉末的沉積效率分別提高了75.80%，181.49%和59.21%。粘接相熔融后對未熔融YSZ粒子和未燒損聚苯酯粒子的黏附和包裹作用是提高涂層沉積效率的主要原因。由于釔鋁石榴石粘接相熔點(diǎn)最低、粒度適中，得到的B2型團(tuán)聚顆粒流動性最好，松裝密度最大，大顆粒所占比例最小，因此B2型涂層具有最高的沉積效率。;Four types of Y2O3 partially stabilized ZrO2 (YSZ)-based agglomerated powder containing no bonding phase, Al2O3, yttrium aluminum garnet (YAG), and MgAl2O, labeled as B0, B1, B2, and B3, respectively, were prepared by spray granulation. And, the flow ability, apparent density and particle size distribution of those powders were investigated. Besides, the deposition efficiency (DE) and bonding mechanism of the four types of agglomerated powder prepared by atmospheric plasma spraying (APS) were analyzed. The results show that, compared with B0 powder, the flowability of B1, B2 and B3 powder is reduced by 6.94%, 5.15% and 25.2%, respectively, the apparent density is reduced by 2.85%, 2.19% and 7.67%, respectively, and the proportion of large-size agglomerated powder is increased by 15.82%, 6.65% and 29.75%, respectively. The DE of B1, B2 and B3 powder is increased by 75.80%, 181.49% and 59.21%, respectively, and the main reason for the improvement of DE is the adhesion and wrapping effect of the bonding phase. Because YAG has the lowest melting point and moderate particle size, B2 powder has the best flowability, the maximum apparent density, and the smallest proportion of large particles, which accordingly results in the strongest adhesion and wrapping effect and eventually leads to the highest DE."/>
