2O3-PF）交替涂層。將Y2O3包覆PF粉末噴涂在基體上生成過(guò)渡層，之后交替沉積球形Y2O3粉末和Y2O3包覆PF粉末形成復(fù)合交替涂層。結(jié)果表明，交替涂層主體由Y2O3包覆PF粉末沉積而成，且涂層與基體結(jié)合強(qiáng)度高達(dá)26.48 MPa，單次最大結(jié)合強(qiáng)度為28.10 MPa，剪切強(qiáng)度高達(dá)24.30 MPa。此外，外部Y2O3粒子產(chǎn)生的熱傳遞效應(yīng)使PF逐漸軟化熔融，從而有效避免了高溫對(duì)分子結(jié)構(gòu)的破壞，促進(jìn)了沉積過(guò)程中樹(shù)脂的交聯(lián)與固化。同時(shí)，未熔Y2O3粉末形成了噴丸效應(yīng)，沖刷去除了沉積效果較差的粉末粒子，最終顯著改善了交替涂層的組織和性能。;High-performance yttrium oxide-phenolic resin (Y2O3-PF) alternating coating was prepared on epoxy resin-based composite material using supersonic plasma spraying and dual-channel powder feeding technique. Y2O3-coated PF (Y2O3/PF) powder was firstly sprayed onto the substrate, forming a transition layer, and then the spherical Y2O3 powder and Y2O3/PF powder were alternately deposited to form the composite alternating coating. Results show that the alternating coating is mainly composed of deposited Y2O3/PF powder. The bonding strength between coating and substrate is as high as 26.48 MPa with the single-test maximum bonding strength of 28.10 MPa, and shear strength reaches 24.30 MPa. Additionally, the heat transfer effect caused by external Y2O3 particles gradually softens and even melts PF, thus effectively avoiding the damage of high temperature to molecular structure and thereby promoting the crosslinking and curing effects of resin during the deposition process. In the meantime, the unmelted Y2O3 powder results in the shot peening effect, which washes out and eliminates the powder particles with inferior deposition effect, ultimately improving the physical and chemical properties of the alternating coating."/>
