Hauv kev tsim cov khoom silicon rau solar hlwb, boron tuaj yeem tshem tawm ntau nrawm dua li yav dhau los hauvSilicon Hlau 553Refining txoj kev ntawm silicon hlau. Hauv lwm lo lus, lub ntshav ntshav muaj pa nrog cov pa roj av uas muaj cov dej ua kua kom tshem tawm cov khoom ua kua hauv molten silicon, thiab roj ntxiv ntxiv rau cov pa ntshav. Boron tuaj yeem tshem tawm tau zoo los ntawm kev hloov kho kom zoo ntawm cov dej vapor / txo cov roj, roj txhaj Hmoo thiab txoj kev cua sov.

Cov Khoom Siv Kev Sib Koom Tes
1.Mo-based solid daws (Moss) nyuaj mo2ni thiabSilicon Hlau 553Hnav-resistant cov khoom tau npaj los ntawm Laser Melting Deposition intitionition technology, thiab cov kev sib tw ntawm lub tshuab pin tau pom nrog kev pab ntawm scanning Electron me me. Moss Tov zog Mo2Ni3Si Hlau Ua Ntej Cov Khaub Ncaws Kub, thiab nws hnav thiab tsis muaj tus yam ntxwv Thiab Moss dendendrites yog me ntsis oxidized ntawm kev sim ntsuas kub. Tus Hlau Ua Si Ntawm Mo2NI3Si ua si ib qho kev tawm tsam hauv cov txheej txheem hnav, thiab cov leeg mossically muaj kev sib tsoo thiab microscopic spalling ntawm mo2ni3Si matrix. Lub zog hnav lub zog ntawm alloy nyob rau hauv high-kub sliders tej yam kev mob yog mos abrasive hnav thiab oxidation ntawm ntxhuab theem.
