Izikebhe ze-Tungsten Evaporation

Emkhakheni omkhulu wesayensi nezimboni zesimanje, isikebhe se-tungsten sivela njengethuluzi elimangalisayo elinezinhlelo zokusebenza ezihlukahlukene nezibalulekile.

Izikebhe ze-Tungsten zenziwe nge-tungsten, insimbi eyaziwa ngezakhiwo zayo ezingavamile.I-Tungsten inephuzu lokuncibilika eliphakeme ngendlela emangalisayo, i-thermal conductivity enhle kakhulu, kanye nokumelana okuphawulekayo nokusabela kwamakhemikhali.Lezi zimfanelo zenza kube yinto ekahle yokwakha imikhumbi engakwazi ukumelana nezimo ezimbi kakhulu.

Enye yezinhlelo zokusebenza eziyinhloko zezikebhe ze-tungsten iwumkhakha we-vacuum deposition.Lapha, isikebhe sishiselwa ezingeni lokushisa eliphezulu ngaphakathi kwegumbi le-vacuum.Izinto ezibekwe esikebheni ziyahwamuka bese zifakwa ku-substrate, zenze amafilimu amancanyana anogqinsi olunemba kanye nokwakheka.Le nqubo ibalulekile ekukhiqizeni ama-semiconductors.Isibonelo, ekukhiqizeni ama-microchips, izikebhe ze-tungsten zisiza ukufaka izendlalelo zezinto ezifana ne-silicon nezinsimbi, zidale umjikelezo oyinkimbinkimbi onika umhlaba wethu wedijithali amandla.

Emkhakheni we-optics, izikebhe ze-tungsten zidlala indima ebalulekile.Asetshenziselwa ukufaka ama-coatings kumalensi nasezibukweni, athuthukise ukubukeka kwawo kanye nokudluliswa kwe-transmissivity.Lokhu kuholela ekusebenzeni okuthuthukisiwe kumishini yokubona efana namakhamera, izibonakude, nezinhlelo ze-laser.

Imboni ye-aerospace nayo iyazuza ezikebheni ze-tungsten.Izingxenye ezivezwe emazingeni okushisa aphezulu nasezimweni ezinzima ngesikhathi sohambo lwasemkhathini zenziwa kusetshenziswa ukubekwa okulawulwayo okwenziwa yilezi zikebhe.Izinto ezifakwe ngale ndlela zinikeza ukumelana nokushisa okuphezulu nokuqina.

Izikebhe ze-Tungsten nazo zisetshenziswa ekuthuthukiseni izinto ezintsha zokugcina amandla nokuguqulwa.Basiza ekuhlanganiseni nasekuboniseni izici zezinto ezisetshenziswayo zamabhethri namaseli kaphethiloli, okuqhuba ukusesha kwezixazululo zamandla ezisebenza kahle nezimeme.

Ocwaningweni lwesayensi yezinto ezibonakalayo, zenza kube lula ukufunda ngokuguquka kwesigaba kanye nezakhiwo zezinto ezingaphansi kwezimo ezilawulwayo zokuhwamuka.Lokhu kusiza ososayensi baqonde futhi balawule ukuziphatha kwezinto ezingeni le-athomu.

Ngaphezu kwalokho, ekukhiqizeni okukhethekile okunamathelayo kwezicelo ezihlukahlukene zezimboni, izikebhe ze-tungsten ziqinisekisa ukufana nokusetshenziswa okunembile kwezinto zokwakha, kuthuthukise ukusebenza nokuphila isikhathi eside kwezindawo ezimboziwe.

Isikebhe se-tungsten siyingxenye ebalulekile kubuchwepheshe obuningi obusezingeni eliphezulu.Amandla ayo okwenza kube lula ukufakwa kwezinto ezilawulwayo kanye nokuhwamuka kuyenza ikwazi ukwenza inqubekelaphambili emikhakheni eminingi, ibumba ikusasa lesayensi nezimboni.

Ibanga lomkhiqizo wethu elijwayelekile

Sikhiqiza izikebhe ezihwamukayo ezenziwe nge-molybdenum, tungsten, ne-tantalum ngohlelo lwakho lokusebenza:

Izikebhe ze-Tungsten evaporation
I-Tungsten imelana nokugqwala kakhulu uma iqhathaniswa nezinsimbi eziningi ezincibilikisiwe futhi, enendawo ephakeme kakhulu yokuncibilika kuzo zonke izinsimbi, ikwazi ukumelana nokushisa kakhulu.Senza okokusebenza ukuthi imelane nokugqwala futhi iqine ngokwengxenye ngokusebenzisa ama-dopants akhethekile njenge-potassium silicate.

Izikebhe ze-Molybdenum evaporation
I-Molybdenum iyinsimbi ezinzile futhi ifaneleka namazinga okushisa aphezulu.Ifakwe i-lanthanum oxide (ML), i-molybdenum idonsa kakhulu futhi imelana nokubola.Sengeza i-yttrium oxide (MY) ukuze sithuthukise ukusebenza kwemishini kwe-molybdenum

Izikebhe ze-Tantalum evaporation
I-Tantalum inomfutho we-vapor ophansi kakhulu kanye nesivinini esiphansi sokuhwamuka.Okuhlaba umxhwele kakhulu ngale nto, nokho, ukumelana kwayo nokugqwala okuphezulu.

Izicelo:
Izikebhe ze-Tungsten zisetshenziswa kakhulu ezimbonini zokumboza i-vacuum noma izimboni ze-vacuum annealing ezifana ne-golide plating, ama-evaporator, izibuko zamashubhu evidiyo, iziqukathi zokufudumeza, umdwebo we-electron beam, izinto zasendlini, izinto zikagesi zabathengi, ama-semiconductors kanye nemihlobiso ehlukahlukene.Qaphela: Ngenxa yokuqina odongeni oluncane lwesikebhe se-tungsten kanye nezinga lokushisa eliphezulu lendawo yokusebenza, kulula ukukhubaza.Ngokuvamile, udonga lwesikebhe lugobile futhi lukhubazekile esikebheni.Uma i-deformation ibucayi, umkhiqizo ngeke ukwazi ukuqhubeka nokusetshenziswa.
