Amacandelo okufudumeza 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: Intambo ye-tungsten ene-annealed ke ijijelwe ukwenza i-filament structure. Inkqubo yokuguqula ilawulwa ngononophelo ukuze kuqinisekiswe ukuba imilinganiselo yefilament efunekayo kunye neempawu zoomatshini ziyafezekiswa. Unyango lobushushu: Intambo ye-tungsten ephothiweyo iphantsi kwenkqubo yonyango lobushushu ukuze iphucule ngakumbi iipropathi zayo zemishini njengamandla kunye ne-ductility. Eli nyathelo lingabandakanya ukufudumeza i-filament kwiqondo lobushushu elithile kwaye emva koko liyipholise phantsi kweemeko ezilawulwayo ukufumana 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 imicu ye-tungsten iphumelele ukuhlolwa kokulawulwa komgangatho, inokuphinda iqhube amanyathelo ongezelelweyo, njengonyango lomphezulu okanye ukufakwa kwe-coating, ukuphucula ukusebenza kwabo 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.
