Tungsten Electrode ya TIG Welding
M'malo akulu asayansi ndi mafakitale amakono, bwato la tungsten limawoneka ngati chida chodabwitsa chomwe chili ndi ntchito zosiyanasiyana komanso zofunikira.
Maboti a Tungsten amapangidwa kuchokera ku tungsten, chitsulo chodziwika ndi zinthu zake zapadera. Tungsten ili ndi malo osungunuka kwambiri, matenthedwe abwino kwambiri, komanso kukana modabwitsa pamachitidwe amankhwala. Makhalidwewa amachititsa kuti zikhale zofunikira kwambiri popanga zombo zomwe zimatha kupirira mikhalidwe yovuta kwambiri.
Chimodzi mwazinthu zoyambira zamabwato a tungsten ndi gawo la vacuum deposition. Apa, bwato limatenthedwa mpaka kutentha kwambiri mkati mwa chipinda chopanda mpweya. Zinthu zomwe zimayikidwa m'ngalawamo zimakhala nthunzi ndikuziyika pagawo laling'ono, kupanga mafilimu opyapyala okhala ndi makulidwe ake komanso mawonekedwe ake. Izi ndizofunikira popanga ma semiconductors. Mwachitsanzo, popanga ma microchips, mabwato a tungsten amathandizira kuyika zigawo za zinthu monga silicon ndi zitsulo, kupanga madera ovuta omwe amathandizira dziko lathu la digito.
M'malo a optics, mabwato a tungsten amagwira ntchito yofunika kwambiri. Amagwiritsidwa ntchito kuyika zokutira pamagalasi ndi magalasi, kupititsa patsogolo mawonekedwe awo komanso kufalikira. Izi zimabweretsa kupititsa patsogolo magwiridwe antchito pazida zowonera monga makamera, ma telescopes, ndi makina a laser.
Makampani opanga ndege amapindulanso ndi mabwato a tungsten. Zinthu zomwe zimakhudzidwa ndi kutentha kwambiri komanso malo ovuta kwambiri panthawi yoyenda mumlengalenga zimapangidwa pogwiritsa ntchito njira zoyendetsedwa ndi mabwatowa. Zinthu zomwe zimayikidwa motere zimapereka kutentha kwapamwamba komanso kulimba.
Maboti a Tungsten amagwiritsidwanso ntchito popanga zida zatsopano zosungira mphamvu ndikusintha. Amathandizira kaphatikizidwe ndi mawonekedwe azinthu zamabatire ndi ma cell amafuta, ndikuyendetsa kufunafuna mayankho ogwira mtima komanso okhazikika.
Mu kafukufuku wa sayansi ya zinthu, amathandizira kuphunzira za kusintha kwa magawo ndi zinthu zomwe zimayendetsedwa ndi evaporation. Izi zimathandiza asayansi kumvetsetsa ndikuwongolera machitidwe a zinthu pamlingo wa atomiki.
Kuphatikiza apo, popanga zokutira zapadera zamafakitale osiyanasiyana, mabwato a tungsten amawonetsetsa kuti zidazo zimagwiritsidwa ntchito moyenera, zomwe zimakulitsa magwiridwe antchito komanso moyo wautali wazomwe zidakutidwa.
Boti la tungsten ndichinthu chofunikira kwambiri pamakina ambiri apamwamba kwambiri. Kuthekera kwake kuwongolera kusungidwa kwazinthu zoyendetsedwa ndi kutulutsa mpweya kumapangitsa kuti chithandizire kupita patsogolo m'magawo angapo, ndikupanga tsogolo la sayansi ndi mafakitale.
Zogulitsa zathu zokhazikika
Timapanga mabwato a evaporation opangidwa ndi molybdenum, tungsten, ndi tantalum kuti mugwiritse ntchito:
Mabwato a Tungsten evaporation
Tungsten imalimbana ndi dzimbiri poyerekeza ndi zitsulo zambiri zosungunuka ndipo, yomwe ili ndi malo osungunuka kwambiri kuposa zitsulo zonse, imapirira kutentha kwambiri. Timapanga zinthuzo kuti zisachite dzimbiri komanso kuti zikhale zokhazikika pogwiritsa ntchito ma dopants apadera monga potaziyamu silicate.
Mabwato a Molybdenum evaporation
Molybdenum ndi chitsulo chokhazikika komanso choyenera kutentha kwambiri. Molybdenum imapangidwa ndi lanthanum oxide (ML), yomwe imakhala ndi ductile komanso yosachita dzimbiri. Timawonjezera yttrium oxide (MY) kuti tipititse patsogolo magwiridwe antchito a molybdenum
Mabwato a evaporation a Tantalum
Tantalum ili ndi mphamvu yotsika kwambiri ya nthunzi komanso liwiro lotsika la evaporation. Chochititsa chidwi kwambiri ndi nkhaniyi, komabe, ndi kukana kwake kwa dzimbiri.
Cerium-Tungsten Electrode
Ma Electrodes a Cerium-Tungsten ali ndi machitidwe abwino oyambira arc pansi pa malo otsika kwambiri. Arc panopa ndi yochepa, choncho maelekitirodi angagwiritsidwe ntchito kuwotcherera chitoliro, zosapanga dzimbiri ndi mbali zabwino. Cerium-Tungsten ndiye chisankho choyamba cholowa m'malo mwa Thoriated Tungsten pansi pa DC yotsika.

Lanthanated Tungsten Electrode
Tungsten ya lanthanated idakhala yotchuka kwambiri padziko lonse lapansi itangopangidwa chifukwa cha ntchito yake yabwino yowotcherera. The madutsidwe magetsi lanthanated tungsten kwambiri chatsekedwa kuti 2% thoriated Tungsten. Owotcherera amatha kusintha mosavuta tungsten Electrode yokhala ndi lanthanated tungsten elekitirodi pa AC kapena DC ndipo samasowa kusintha pulogalamu iliyonse yowotcherera. The radioactivity kuchokera thoriated tungsten akhoza kupewedwa. Ubwino wina wa lanthanated tungsten ndikutha kupirira kwambiri pakali pano komanso kukhala ndi chiwopsezo chotsika kwambiri chotayika.

Zirconiated Tungsten Electrode
Zirconiated tungsten imakhala ndi ntchito yabwino mu kuwotcherera kwa AC, makamaka pansi pa katundu wambiri wapano. Maelekitirodi ena aliwonse malinga ndi magwiridwe ake abwino kwambiri sangalowe m'malo mwa ma elekitirodi a Zirconated tungsten. Elekitirodi imakhala ndi malekezero a balled pamene kuwotcherera, zomwe zimapangitsa kuti tungsten ikhale yochepa komanso kukana kwa dzimbiri.
Ogwira ntchito athu aukadaulo akhala akuchita kafukufuku ndi kuyesa ntchito ndipo akwanitsa kuthetsa mikangano pakati pa zomwe zili zirconium ndikukonza katundu.
