zinthu zotenthetsera molybdenum W mawonekedwe U mawonekedwe waya wotenthetsera
Zinthu zotenthetsera za molybdenum zooneka ngati W zidapangidwa kuti zizipereka malo otenthetsera okulirapo, kuwapangitsa kukhala oyenera kugwiritsa ntchito zomwe zimafunikira kutentha kwa yunifolomu kwamadera akulu. Amagwiritsidwa ntchito kwambiri m'ng'anjo zamafakitale, njira zochizira kutentha komanso kupanga semiconductor.
Komano, zinthu zotenthetsera zokhala ndi mawonekedwe a U-molybdenum ndizoyenera kugwiritsa ntchito zomwe zimafuna kutenthetsa kwambiri pamalo enaake. Amagwiritsidwa ntchito kwambiri pamakina monga ng'anjo za vacuum, njira za sintering komanso kutentha kwambiri kwamankhwala.
Zinthu zonse zotentha za molybdenum zooneka ngati W komanso zooneka ngati U zitha kupangidwa pogwiritsa ntchito waya wotenthetsera wa molybdenum, womwe umadziwika chifukwa cha kutentha kwambiri komanso kulimba kwake. Waya wowotchera amatha kulumikizidwa ndikuwumbidwa munjira yomwe mukufuna kuti apange zinthu zotenthetsera zoyenera komanso zodalirika pazogwiritsa ntchito zosiyanasiyana zamafakitale ndi sayansi.

Mikhalidwe yogwiritsira ntchito waya wotentha wa molybdenum makamaka imaphatikizapo malo ogwiritsira ntchito, kukula ndi mawonekedwe ake, kusankha resistivity, ndi njira yoyika.
Malo ogwiritsira ntchito: Waya wotenthetsera wa Molybdenum nthawi zambiri amagwiritsidwa ntchito pamalo otetezedwa ndi mpweya kapena mpweya, monga pazida zotentha kwambiri monga ng'anjo za vacuum. Kusankhidwa kwa chilengedwechi kumathandizira kukhalabe okhazikika kwa waya wotentha wa molybdenum ndikukulitsa moyo wake wautumiki.
Kukula ndi kapangidwe kake: Kukula ndi mawonekedwe a chingwe chotenthetsera cha molybdenum chiyenera kutsimikiziridwa molingana ndi kukula ndi kapangidwe ka mkati mwa ng'anjo ya vacuum kuti zitsimikizire kuti zimatha kutentha zinthu zomwe zili mkati mwa ng'anjoyo. Nthawi yomweyo, mawonekedwe a mzere wotenthetsera wa molybdenum amafunikanso kuganizira za kuyika kwa zinthu ndi njira yopangira kutentha kuti apititse patsogolo kutentha.
Kusankhidwa kwa resistivity: Resistivity ya mzere wotentha wa molybdenum idzakhudza kutentha kwake komanso kugwiritsa ntchito mphamvu. Nthawi zambiri, kutsika kwa resistivity, kumapangitsanso kutentha kwabwino, koma kugwiritsa ntchito mphamvu kumawonjezekanso moyenerera. Choncho, popanga mapangidwe, m'pofunika kusankha resistivity yoyenera malinga ndi zosowa zenizeni.
Njira yoyikira: Mzere wotenthetsera wa molybdenum uyenera kukhazikika pa bulaketi mkati mwa ng'anjo ya vacuum ndikusungidwa patali kuti athetse kutentha. Nthawi yomweyo, chidwi chiyenera kuperekedwa popewa kukhudzana kwachindunji pakati pa mzere wotenthetsera wa molybdenum ndi khoma la ng'anjo kuti mupewe mabwalo amfupi kapena kutenthedwa.
Mikhalidwe yogwiritsira ntchito imeneyi imatsimikizira kugwira ntchito ndi chitetezo cha mawaya otenthetsera a molybdenum m'malo enaake, komanso kupereka zitsimikizo pakugwiritsa ntchito kwawo kumalo otentha kwambiri.
Nthawi yomwe imatengera ng'anjo ya waya ya molybdenum kutentha mpaka madigiri 1500 Celsius imatha kusiyanasiyana kutengera ng'anjo yeniyeni, mphamvu yake komanso kutentha koyambirira kwa ng'anjoyo. Komabe, akuti ng'anjo yotentha kwambiri yomwe imatha kufika madigiri 1500 Celsius ingatenge pafupifupi mphindi 30 mpaka 60 kuti itenthedwe kuchokera kuchipinda kupita ku kutentha komwe kumafunikira.
Ndizofunikira kudziwa kuti nthawi zotenthetsera zimatha kukhudzidwa ndi zinthu monga kukula kwa ng'anjo ndi kutsekereza, kuyika mphamvu, ndi chinthu china chotenthetsera chomwe chimagwiritsidwa ntchito. Kuonjezera apo, kutentha koyambirira kwa ng'anjo ndi malo ozungulira malo ozungulira kumakhudzanso nthawi yotentha.
Kuti mupeze nthawi yowotchera yolondola, tikulimbikitsidwa kuti titchule zomwe wopanga amapanga komanso malangizo ang'anjo ya molybdenum yomwe ikugwiritsidwa ntchito.
Mpweya wabwino kwambiri wa ng'anjo za waya wa molybdenum nthawi zambiri umakhala wosayera kwambiri wa haidrojeni. Chifukwa hydrogen ndi inert ndi kuchepetsa, nthawi zambiri amagwiritsidwa ntchito m'ng'anjo zotentha kwambiri za molybdenum ndi zitsulo zina zokanira. Akagwiritsidwa ntchito ngati mpweya wa ng'anjo, haidrojeni imathandiza kupewa okosijeni ndi kuipitsidwa kwa waya wa molybdenum pa kutentha kwakukulu.
Kugwiritsiridwa ntchito kwa hydrogen yoyera kwambiri kumathandiza kuti pakhale mpweya wabwino komanso woyendetsedwa bwino mkati mwa ng'anjo, zomwe ndizofunikira kwambiri kuti ma oxide asapangidwe pa waya wa molybdenum panthawi yotentha. Izi ndizofunikira kwambiri chifukwa molybdenum imatulutsa okosijeni mosavuta pakatentha kwambiri, ndipo kupezeka kwa okosijeni kapena mpweya wina wotuluka kumatha kuchepetsa magwiridwe ake.
Ndikofunika kuonetsetsa kuti haidrojeni yomwe imagwiritsidwa ntchito ndi yoyera kwambiri kuti ichepetse chiopsezo cha kuipitsidwa ndi kusunga zofunikira za waya wa molybdenum. Kuonjezera apo, ng'anjoyo iyenera kupangidwa kuti igwire bwino ndikuwongolera kutuluka kwa haidrojeni kuti iwonetsetse kuti ikugwira ntchito bwino. Mukamagwiritsa ntchito haidrojeni kapena mpweya wina uliwonse mung'anjo ya molybdenum, nthawi zonse tsatirani malangizo a wopanga ndi malingaliro otetezeka.
