Tungstenifaneleke ngokukodwa njengesixhobo seendawo ezinoxinzelelo oluphezulu lwenqanawa evale iplasma eshushu ye-fusion, iyintsimbi eneyona ndawo iphezulu yokunyibilika.Noko ke, undonakele, bubunkunkqele bayo, obuthi ngenxa yoxinezeleko buyenze ibe buthathaka kwaye ibe sengozini yokonakala.Inoveli, imathiriyeli eyomelela ngakumbi ngoku iye yaphuhliswa yiMax Planck Institute yePlasma Physics (IPP) eGarching.Iqukethe i-homogeneousi-tungstenenecoatediingcingo ze-tungstenifakwe.Uphononongo lokwenyani lusandula ukubonisa ukufaneleka okusisiseko kwekhompawundi entsha.

Injongo yophando oluqhutywe kwi-IPP kukuphuhlisa iplanti yamandla ethi, njengelanga, ifumane amandla ekudibaneni kweenuclei zeatom.Amafutha asetyenzisiweyo yi-low-density hydrogen plasma.Ukuphemba umlilo wokudibanisa i-plasma kufuneka ivalelwe kwiindawo zemagneti kwaye ifudunyezwe kubushushu obuphezulu.Embindini we-100 lezigidi zeedigri zifunyenwe.Tungstensisinyithi esithembisa kakhulu njengesixhobo samalungu adibana ngqo neplasma eshushu.Oku kubonakaliswe luphando olubanzi kwi-IPP.Ingxaki engekasonjululwa ukuza kuthi ga ngoku, ibe bububhetyebhetye besixhobo:Tungstenilahlekelwa ukuqina kwayo phantsi kweemeko zeplanti yamandla.Uxinzelelo lwendawo - uxinzelelo, ukolula okanye uxinzelelo - alunakuthintelwa yimathiriyeli enika indlela kancinane.Endaweni yoko iintanda zenza iintanda: Amacandelo ke ngoko asabela ngovakalelo kakhulu kumthwalo ogqithileyo wengingqi.

Yiyo loo nto i-IPP yakhangela izakhiwo ezikwaziyo ukusasaza uxinzelelo lwasekhaya.Iiseramics ezomelezwe ngefayibha zisebenza njengemizekelo: Umzekelo, i-silicon carbide brittle brittle yenziwe ngokuphindwe kahlanu ngokomelela xa yomelezwa ngeentsinga zesilicon carbide.Emva kwezifundo ezimbalwa zokuqala ze-IPP isazinzulu uJohann Riesch wayeza kuphanda ukuba unyango olufanayo lunokusebenza nge-tungsten metal.

Inyathelo lokuqala yaba kukuvelisa izinto ezintsha.AtungsteI-matrix kufuneka iqiniswe ngemicu emide egqunyiweyo equka i-extrudeducingo lwe-tungstenzibhityile njengeenwele.Iingcingo, ekuqaleni zazijongwe njengokukhanyaimicukwiibhalbhu zokukhanya, apho zibonelelwa ngu-Osram GmbH.Izixhobo ezahlukeneyo zokuzigquma zaphandwa kwi-IPP, kubandakanywa i-erbium oxide.Igqunywe ngokupheleleyoiintambo ze-tungstenZaye zidityaniswe ndawonye, ​​mhlawumbi zidibene okanye zilukwe.Ukuzalisa izithuba phakathi kweengcingo kunye ne-tungsten uJohann Riesch kunye nabasebenzi asebenza nabo emva koko baphuhlise inkqubo entsha ngokubambisana nesiNgesi iqabane kwishishini Archer Technicoat Ltd. indlela ethambileyo yokuvelisa ikhompawundi yafunyanwa: Ii-tungstenifakwe kwiingcingo ezivela kumxube wegesi ngokufaka inkqubo yeekhemikhali kumaqondo obushushu aphakathi.Yayikokokuqala okoi-tungsten-fiber-yomelezwe i-tungstenyaveliswa ngempumelelo, ngesiphumo esifunwayo: Ukuqina kokwaphuka kwekhompawundi entsha sele kuphindwe kathathu ngokunxulumene ne-fibreless tungsten emva kovavanyo lokuqala.

Inyathelo lesibini yayikukuphanda ukuba oku kusebenza njani: Eyona nto ibalulekileyo yangqina ukuba ibhulorho yeefibers iyaqhekeka kwi-matrix kwaye inokusasaza amandla asebenza kwindawo kwimathiriyeli.Apha i-interfaces phakathi kwe-fibers kunye ne-tungsten matrix, kwelinye icala, kufuneka ibe buthathaka ngokwaneleyo ukuba inike indlela xa iintanda zenzeke kwaye, kwelinye, zibe namandla ngokwaneleyo ukuhambisa amandla phakathi kweentsinga kunye ne-matrix.Kwiimvavanyo zokugoba oku kunokubonwa ngokuthe ngqo ngeX-reyi microtomography.Oku kubonise ukusebenza okusisiseko kwemathiriyeli.

Isigqibo malunga nokusebenziseka kwemathiriyeli, nangona kunjalo, kukuba ukomelela okongeziweyo kuyagcinwa xa isetyenziswa.UJohann Riesch ukhangele oku ngokuphanda iisampulu ebezifakwe kunyango lwangaphambili lwe-thermal.Xa iisampulu ziphantsi kwemitha ye-synchrotron okanye zibekwe phantsi kwe-electron microscope, ukuzolula kunye nokugoba nazo ziqinisekisiwe kulo mzekelo iimpawu zezinto eziphathekayo eziphuculweyo: Ukuba i-matrix iyasilela xa igxininisekile, iifayili ziyakwazi ukuvala iintanda ezenzeka kwaye ziqhube.

Imigaqo yokuqonda nokuvelisa umbandela omtsha izinzile.Iisampulu ngoku kufuneka ziveliswe phantsi kweemeko eziphuculweyo zenkqubo kunye nojongano olulungisiweyo, oku kungumba ofunekayo kwimveliso enkulu.Isixhobo esitsha sinokuba nomdla ngaphaya kwendawo yophando lokudibanisa.
