Izixhobo zokufudumeza iTungsten Twisted Filament yoshishino lwesemiconductor
Ukuveliswa kwe-tungsten skeins ngokuqhelekileyo kubandakanya amanyathelo amaninzi:
Ukukhetha ucingo lweTungsten: Sebenzisa ucingo lwe-tungsten olusulungekileyo njengemathiriyeli ekrwada.Ucingo lukhethwe ngenxa yamandla alo akhethekileyo, indawo ephezulu yokunyibilika kunye nokumelana nokugqwala, okwenza ukuba ilungele ukusetyenziswa kwizicelo zobushushu obuphezulu.Ukufakwa kwentambo yocingo: Ucingo lwetungsten olukhethiweyo luye lwabanjwa ukuze luphucule ukuductility kwalo kwaye luququzelele inkqubo yokujija elandelayo.I-Annealing kukufudumeza ucingo kwiqondo lobushushu eliphezulu kwaye emva koko lupholise kancinane, olunceda ukususa uxinzelelo lwangaphakathi kwaye lwenza ucingo lube lukhuni ngakumbi.Inkqubo yokujija: I-annealed tungsten wire ijijelwe ukwenza i-filament structure.Inkqubo yokuguqula ilawulwa ngononophelo ukuqinisekisa ukuba imilinganiselo yefilament efunekayo kunye neempawu zomatshini ziyafezekiswa.Unyango lobushushu: Intambo ye-tungsten ephothiweyo iphantsi kwenkqubo yonyango lobushushu ukuze iphucule ngakumbi iimpawu zayo zokwenza izinto ezifana namandla kunye ne-ductility.Eli nyathelo lingabandakanya ukufudumeza i-filament kwiqondo lobushushu elithile kwaye emva koko uyipholise phantsi kweemeko ezilawulwayo ukuze ufumane isakhiwo se-metallographic esifunekayo.Ukulawulwa koMgangatho kunye noVavanyo: Kuyo yonke inkqubo yokuvelisa, amanyathelo okulawula umgangatho aphunyezwa ukuqinisekisa ukuba ucingo lwe-tungsten ludibana neenkcukacha ezifunekayo.Oku kunokubandakanya ukuvavanya amandla oomatshini bomatshini, ukuchaneka kobukhulu kunye nezinye iimpawu eziphambili.Ukucutshungulwa kokugqibela: Emva kokuba iintambo ze-tungsten ziphumelele ukuhlolwa kokulawulwa komgangatho, zinokuthi ziqhubele phambili amanyathelo ongezelelweyo, njengonyango lwangaphandle okanye ukufakwa kwe-coating, ukunyusa ukusebenza kwazo kwizicelo ezithile.
Ukuveliswa kwe-tungsten stranded wire kufuna ubuchule bokuvelisa ngokuchanekileyo kunye nokulawulwa ngokucokisekileyo kwezinto eziphathekayo ukuze kuqinisekiswe ukuba ucingo olubangelwayo luhlangabezana neemfuno eziphezulu zokushisa kunye neempawu zomatshini ezifunekayo kwizicelo ezifana nokuveliswa kwe-semiconductor.
I-twisted tungsten filament idla ngokusetyenziswa kwiibhalbhu ze-incandescent kunye nezinye izinto ezahlukeneyo zokukhanyisa.Iimpawu ezikhethekileyo zeTungsten, kubandakanya indawo yayo ephezulu yokunyibilika kunye ne-thermal conductivity egqwesileyo, yenza kube yinto efanelekileyo yeefilaments ekufuneka imelane namaqondo obushushu aphezulu ngelixa igcina ingqibelelo yesakhiwo ngexesha lokusebenza.Kwibhalbhu yokukhanya kwe-incandescent, umbane wombane udlula kwi-tungsten filament ephothiweyo, ebangela ukuba ishushu kwaye ikhuphe ukukhanya okubonakalayo.I-twisting ye-filament inceda ukwandisa indawo yayo, ivumela ukutshatyalaliswa kokushisa okusebenzayo kunye nokukhutshwa kokukhanya.Olu luyilo lukwanceda ukwandisa amandla kunye nokuqina kwe-filament, evumela ukuba imelane noxinzelelo lwe-thermal kunye noomatshini abafumana ngexesha lokusebenza.Ucingo lweTungsten lukwasetyenziswa kwizinto ezikhethekileyo zokufudumeza, izixhobo ze-electron beam, kunye neentlobo ngeentlobo zezicelo zobushushu obuphezulu apho ukumelana ne-corrosion kunye nokusebenza okungaguqukiyo kumaqondo obushushu aphezulu kubaluleke kakhulu.
Ngokubanzi, ukusetyenziswa kwentambo ye-tungsten ephothiweyo kudlala indima ebalulekileyo ekuboneleleni okuthembekileyo, ukukhanya okusebenzayo kunye nezisombululo zokufudumeza kwiindidi ezahlukeneyo zoshishino, urhwebo, kunye nezicelo zokuhlala.
