Iinqanawa zeTungsten zokuPhuma kweThermal
Inqanawa yeTungsten
Isikhephe se-tungsten sisitya esenziwe ngentsimbi ye-tungsten.Idla ngokubunjwa njengephenyane kwaye yenzelwe ukuqulatha okanye ukuthutha imathiriyeli kwiinkqubo ezahlukeneyo zobushushu obuphezulu.Izikhephe ze-Tungsten zisetyenziswa ngokubanzi kwiinkqubo zokubeka i-vacuum ezifana nokuphuma kwe-thermal kunye nokunyuka kwe-electron beam, efuna ulawulo oluchanekileyo lwezinto ezigciniweyo.
Izikhephe ze-Tungsten zezona zikhethwa kuqala kwi-vacuum deposition ngenxa yendawo yazo yokunyibilika ephezulu kakhulu (3422 ° C), i-thermal conductivity egqwesileyo, kunye nokuxhathisa ukothuka kwe-thermal kunye nokubola kweekhemikhali.Ezi zakhiwo zenza izikhephe ze-tungsten zilungele ukuphatha kunye nemathiriyeli yokukhupha umphunga kumaqondo obushushu aphezulu ngaphandle kokonakala okanye ukusabela ngezinto ezifakiweyo.
Kwinkqubo yokufakwa kwevacuum, izinto eziza kukhutshelwa zibe ngumphunga zibekwe ngaphakathi kwisikhephe se-tungsten kwaye emva koko zifudunyezwe kwiqondo lobushushu elifunekayo kusetyenziswa ukufudumeza okuxhathisayo okanye i-electron beam bombardment.Xa izinto zifikelela kwiqondo lokushisa lokunyuka kwe-evaporation, liyaphuphuma kwaye lenze ifilimu encinci kwizinto ezisisiseko, ukuvumela ulawulo oluchanekileyo lwenkqubo yokubeka kunye neempawu zefilimu ebangelwayo.
Izikhephe zeTungsten ziyafumaneka kwiindidi ezahlukeneyo zobukhulu kunye nohlengahlengiso ukulungiselela iinkqubo ezahlukeneyo zokubeka kunye neemfuno zezinto.Sinikezela ngezikhephe zokunyuka komphunga ngobude obahlukeneyo, ububanzi, ubukhulu, kunye nezixhobo, nceda uqhagamshelane nathi ngeenkcukacha.
