    摘要:

    針對新一代航空發(fā)動機和重型燃氣輪機對長壽命、高韌性熱障涂層的迫切需求，本文通過噴霧造粒法制備了長徑比為10的ZrO2晶須復(fù)合YSZ噴涂粉末，采用SAPS技術(shù)制備了YSZ/ZrO2晶須増韌陶瓷復(fù)合涂層，對復(fù)合涂層的工藝參數(shù)進行優(yōu)化，研究了熔融指數(shù)對陶瓷復(fù)合涂層微觀結(jié)構(gòu)的影響規(guī)律；通過狹縫法收集單個攤片的實驗，闡明了ZrO2晶須增韌YSZ陶瓷涂層的形成機理，建立了晶須増韌陶瓷涂層的微觀結(jié)構(gòu)與熱力學(xué)性能的內(nèi)在關(guān)系?；诰ы殢浬⒎植加趶?fù)合涂層未熔顆粒區(qū)的特征，相比納米結(jié)構(gòu)YSZ涂層，YSZ/ZrO2晶須増韌陶瓷復(fù)合涂層的斷裂韌性與熱循環(huán)壽命均提高一倍。

    Abstract:

    In view of the urgent need of the new generation of aero-engine and heavy duty gas turbine for long life and high toughness thermal barrier coatings, a ZrO2 whisker composite YSZ spray powder with a aspect ratio of 10 has been prepared by spray granulation. The YSZ/ZrO2 whisker toughened ceramic composite coating has been prepared by SAPS technology, and the process parameters of the composite coating have been optimized. The effect of melt index on the microstructure of ceramic composite coating was studied; The formation mechanism of YSZ ceramic coating toughened by ZrO2 whisker was elucidated through the experiment of collecting single slice by slit method. The internal relationship between microstructure and thermodynamic properties of YSZ ceramic coating toughened by ZrO2 whisker was established. Based on the characteristics of whiskers dispersed in the unmelted particle area of the composite coating, the fracture toughness and thermal cycle life of YSZ / ZrO2 whisker toughened ceramic composite coating are doubled compared with nanostructured YSZ coating.
