Izingxenye Zokushisa I-Tungsten Twisted Filament yemboni ye-semiconductor

Incazelo emfushane:

Intambo ye-tungsten ephothiwe ivamise ukusetshenziswa ezinhlelweni ezifana nezifakeli ze-ion, izinhlelo zokubeka i-vacuum, nezinhlelo ze-electron beam embonini ye-semiconductor. Lezi zinto zokushisisa zinikeza ukuzinza okuhle kakhulu kwezinga lokushisa eliphezulu, ukucindezela komhwamuko ophansi kanye nezakhiwo eziqinile zemishini, okuzenza zibe zilungele ukudinga indawo yokucubungula i-semiconductor. Lapho uthenga intambo ye-tungsten eboshiwe yemboni ye-semiconductor, kubalulekile ukucabangela izici ezifana nobubanzi be-filament, ubude, iphimbo, ukuphela kwendawo, kanye nezakhiwo ezishisayo.

Indlela Yokukhiqiza Ye-Tungsten Twisted Filament

Ukukhiqizwa kwama-tungsten skein ngokuvamile kuhilela izinyathelo ezimbalwa:

Ukukhetha intambo ye-Tungsten: Sebenzisa i-high-purity tungsten wire njengempahla eluhlaza. Ucingo lwakhethwa ngenxa yamandla alo angavamile, indawo ephakeme yokuncibilika kanye nokumelana nokugqwala, okulwenza lufanelekele ukusetshenziswa ekusetshenzisweni kwezinga lokushisa eliphezulu. Ukukhipha intambo: Intambo ye-tungsten ekhethiwe ikhishiwe ukuze kuthuthukiswe i-ductility yayo futhi kube lula inqubo yokusonta elandelayo. I-Annealing ukushisisa intambo ibe izinga lokushisa eliphezulu bese ipholisa kancane, okusiza ukususa ingcindezi yangaphakathi futhi kwenza ucingo lube lukhuni kakhulu. Inqubo yokusonta: Intambo ye-tungsten ene-anneal isuke isontiwe ukuze yakhe isakhiwo somucu. Inqubo yokusonta ilawulwa ngokucophelela ukuze kuqinisekiswe ukuthi ubukhulu be-filament obudingekayo kanye nezakhiwo zemishini ziyafinyelelwa. Ukwelashwa kokushisa: Intambo ye-tungsten esontekile ingaphansi kwenqubo yokwelashwa kokushisa ukuze iqhubeke nokuthuthukisa izici zayo zokusebenza ezifana namandla kanye ne-ductility. Lesi sinyathelo singase sifake ukushisisa umcu kuzinga lokushisa elithile bese sipholiswa ngaphansi kwezimo ezilawulwayo ukuze kutholwe isakhiwo se-metallographic esifunekayo. Ukulawula Ikhwalithi Nokuhlola: Kuyo yonke inqubo yokukhiqiza, izinyathelo zokulawula ikhwalithi ziyasetshenziswa ukuze kuqinisekiswe ukuthi intambo ye-tungsten ihlangabezana nokucaciswa okudingekayo. Lokhu kungase kuhlanganise ukuhlola amandla emishini ye-filament, ukunemba kobukhulu kanye nezinye izici ezibalulekile. Ukucutshungulwa kokugcina: Uma imicu ye-tungsten isiphumelele ukuhlolwa kokulawulwa kwekhwalithi, ingase ibhekane nezinyathelo ezengeziwe zokucutshungulwa, njengokwelashwa kwendawo noma ukufakwa kokumboza, ukuze kuthuthukiswe ukusebenza kwazo ezinhlelweni ezithile.

Ukukhiqizwa kocingo olucijile lwe-tungsten kudinga amasu okukhiqiza anembayo kanye nokulawula ngokucophelela izakhiwo zezinto ezibonakalayo ukuze kuqinisekiswe ukuthi ucingo oluvelayo luhlangabezana nezimfuneko zokushisa okuphezulu kanye nezakhiwo zemishini ezidingekayo ekusetshenzisweni okufana nokukhiqizwa kwe-semiconductor.

Ukusetshenziswa KweI-Tungsten Twisted Filament

Umcu we-tungsten osontekile uvame ukusetshenziswa kumalambu okukhanya kwe-incandescent nakwezinye izinhlelo zokusebenza zokukhanyisa ezihlukahlukene. Izakhiwo eziyingqayizivele ze-Tungsten, okuhlanganisa indawo yayo ephezulu yokuncibilika kanye nokuhamba kahle kwe-thermal, kuyenza ibe into efanelekile yamafilaments okumele imelane namazinga okushisa aphezulu kuyilapho igcina ubuqotho besakhiwo ngesikhathi sokusebenza. Kusibani sokukhanya kwe-incandescent, amandla kagesi adlula kumcu osontekile we-tungsten, okuwubangela ukuba ushise futhi ukhiphe ukukhanya okubonakalayo. Ukusonteka kwe-filament kusiza ukwandisa indawo yayo, okuvumela ukuchithwa kokushisa okuphumelelayo nokukhipha ukukhanya. Lo mklamo uphinde usize ukwandisa amandla nokuqina kwe-filament, ukuyivumela ukuthi imelane nezingcindezi ezishisayo nezomshini ezitholakala ngesikhathi sokusebenza. Intambo ye-Tungsten iphinde isetshenziswe ezintweni zokushisisa ezikhethekile, amadivaysi e-electron beam, kanye nezinhlobonhlobo zezinhlelo zokusebenza ezisezingeni eliphezulu lokushisa lapho ukumelana nokugqwala nokusebenza okungaguquki emazingeni okushisa aphezulu kubaluleke kakhulu.

Sekukonke, ukusetshenziswa kwentambo ye-tungsten eboshiwe kudlala indima ebalulekile ekunikezeni ukukhanya okuthembekile, okuphumelelayo nezixazululo zokushisa zezinhlelo zokusebenza ezihlukene zezimboni, ezentengiselwano, nezindawo zokuhlala.
