529上午940,國家杰出青年、芙蓉學(xué)者中國科學(xué)院長春應(yīng)用化學(xué)研究所百人計劃學(xué)者、我校湖湘學(xué)者特聘教授、化學(xué)與生物工程學(xué)院院長曹學(xué)強(qiáng)教授在2011化學(xué)工程與先進(jìn)材料國際學(xué)術(shù)會議(CEAM 2011大會上做了題為《Thermal Barrier Coatings of Rare Earth Materials Deposited by Electron Beam-Physical Vapor Deposition》的主題報告(Keynote Speech)。報告會在長沙市五華大酒店湘江廳舉行,長沙理工大學(xué)副校長付宏淵教授、長沙理工大學(xué)科技處處長劉永樂教授、美國紐約州立大學(xué)(State University of New York at Binghamton,USA)鐘傳建教授、澳大利亞詹姆斯庫克大學(xué)(James Cook UniversityAustralia)何英和教授、中科院大連化學(xué)物理研究所孫立賢教授、湖南師范大學(xué)化學(xué)化工學(xué)院院長尹篤林教授、湖南大學(xué)化學(xué)化工學(xué)院向建南教授、長沙理工大學(xué)化學(xué)與生物工程學(xué)院常務(wù)副院長楊道武教授、長沙理工大學(xué)化學(xué)與生物工程學(xué)院副院長曹忠教授等出席了報告會,共有來自美國、英國、德國、日本、中國等15個國家和地區(qū)的500多名化工和材料方面的專家學(xué)者參加了報告會。

首先,由大會共同主席何英和教授介紹了曹學(xué)強(qiáng)教授的工作經(jīng)歷及研究成果情況。隨后,曹學(xué)強(qiáng)教授介紹了熱障涂層材料的研究歷史、研究進(jìn)展及發(fā)展前景,并對其課題組近幾年來開展的熱障涂層領(lǐng)域的工作做了詳盡的介紹;最后,曹學(xué)強(qiáng)教授還和與會專家學(xué)者就稀土材料熱障涂層相關(guān)領(lǐng)域的學(xué)術(shù)問題進(jìn)行了深入的討論,引起大家的濃厚興趣。

整個報告會加深了大家對稀土熱障涂層材料的認(rèn)識和了解,同時也為各領(lǐng)域的專家學(xué)者提供了新的研究思路。通過這次報告會,化學(xué)與生物工程學(xué)院的師生們開闊了眼界,增長了見識,擴(kuò)大了交流,對于促進(jìn)我院科學(xué)研究與學(xué)科建設(shè)等工作具有重要意義

Abstract:

Thermal barrier coatings (TBCs) have very important applications in gas turbines for higher thermal efficiency and protection of components at high temperature. TBCs of rare earth materials such as lanthanum zirconate (La2Zr2O7, LZ), lanthanum cerate (La2Ce2O7, LC), lanthanum cerium zirconate (La2(Zr0.7Ce0.3)2O7, LZ7C3) were prepared by electron beam-physical vapor deposition (EB-PVD). The composition, crystal structure, cross-sectional morphology and cyclic oxidation behavior of these coatings were studied. A double ceramic layer-thermal barrier coatings (DCL-TBCs) of LZ7C3 and LC could also be deposited with a single LZ7C3 ingot by properly controlling the deposition energy. The failure of DCL-TBCs is a result of the sintering-induced of LZ7C3 coating and the chemical incompatibility of LC and TGO. Since no single material that has been studied so far satisfies all the requirements for high temperature applications, DCL-TBCs is an important development direction of TBCs.
