Tungsten ndi molybdenum ndi zinthu zosinthika zomwe zimakhala ndi malo osungunuka kwambiri komanso okhazikika omwe amawapangitsa kukhala oyenerera ntchito zosiyanasiyana. Zinthu zonsezi zimagwiritsidwa ntchito ngati mabwato otulutsa nthunzi chifukwa cha kukana kwawo kutentha komanso kutsika kwa nthunzi. Komabe, pali kusiyana pakati pa mabwato a tungsten ndi molybdenum potengera ntchito zawo, zomwe tikambirana m'nkhaniyi.

Mabwato a Tungsten:

Mabwato a Tungsten amagwiritsidwa ntchito kwambiri popanga zitsulo ndi ma alloys, komanso zinthu zakuthupi. Izi zimachitika chifukwa cha kusungunuka kwawo kwakukulu (3,422 ° C) ndi kutsika kwa nthunzi, komwe kumapereka gwero loyera la evaporation. Kuphatikiza apo, mabwato a tungsten amagwiritsidwanso ntchito m'makampani a semiconductor ngati chinthu chotenthetsera chifukwa cha kutentha kwawo kwakukulu komanso kukhazikika kwamakina pakatentha kwambiri.

Mabwato a Tungsten amapezeka mosiyanasiyana komanso kukula kwake, kuphatikiza zozungulira, zamakona anayi, ndi zozungulira. Mabwato ozungulira a tungsten amagwiritsidwa ntchito kwambiri pakutentha kwa kutentha, pomwe mabwato a cylindrical tungsten amagwiritsidwa ntchito potenthetsa zinthu. Mabwato a tungsten amakona anayi amagwiritsidwa ntchito popanga evaporation ndi kutentha.

Choyipa chimodzi cha mabwato a tungsten ndi chizolowezi chochita ndi zinthu zina. Mwachitsanzo, mabwato a tungsten amatha kuchitapo kanthu ndi zinthu zina za okosijeni monga madzi, okosijeni, ndi nayitrogeni kupanga tungsten oxide, zomwe zingayambitse kuwonongeka kwa chinthu chotenthetsera. Chifukwa chake, ndikofunikira kuyendetsa mabwato a tungsten pamalo opanda mpweya kapena mumlengalenga.

Mabwato a Molybdenum:

Maboti a molybdenum amagwiritsidwanso ntchito kwambiri pakutulutsa zitsulo, ma aloyi, ndi zinthu zachilengedwe. Maboti a Molybdenum ali ndi malo osungunuka a 2,610 ° C ndi mphamvu ya nthunzi yotsika, zomwe zimawapangitsa kukhala abwino kwambiri pogwiritsira ntchito kutentha kwakukulu. Amagwiritsidwanso ntchito m'makampani a semiconductor, makamaka popanga zida za silicon.

Maboti a Molybdenum amapezeka mosiyanasiyana komanso kukula kwake, kuphatikiza zozungulira, zamakona anayi, ndi zozungulira. Mabwato ozungulira a molybdenum amagwiritsidwa ntchito ngati mpweya wotentha, pomwe mabwato a cylindrical molybdenum amagwiritsidwa ntchito ngati zinthu zotenthetsera.

Maboti a Molybdenum ali ndi chizolowezi chochepa chochita ndi zinthu zosiyanasiyana, poyerekeza ndi mabwato a tungsten. Izi zimachitika chifukwa cha kukhazikika kwamankhwala kwa molybdenum komwe kumapangitsa kuti zisagwirizane ndi oxidizing komanso kuchepetsa malo. Choncho, ndi abwino kwa zipangizo zomwe zimafuna khalidwe lokhazikika komanso chiyero.

Mwachidule, mabwato onse a tungsten ndi molybdenum ali ndi zinthu zapadera zomwe zimawapangitsa kukhala abwino kwa ntchito zosiyanasiyana. Maboti a Tungsten ndi oyenera kutenthetsa ndi kutentha kwa kutentha komwe kumafunikira malo osungunuka kwambiri komanso kukhazikika. Komano, mabwato a molybdenum ndi abwino kwa ntchito zotentha kwambiri zomwe zimafuna kukhazikika kwa mankhwala komanso kukana kutsekemera ndi kuchepetsa. Chifukwa chake, ndikofunikira kuganizira momwe mungagwiritsire ntchito posankha pakati pa mabwato a tungsten ndi molybdenum.
