Ndodo zozungulira za Molybdenum zimagwiritsidwa ntchito kwambiri m'mafakitale otenthetsera kutentha komanso kutentha chifukwa cha kutentha kwambiri. Malo osungunuka a Molybdenum, matenthedwe apamwamba kwambiri komanso kutsika kwapakati pakukula kwamafuta kumapangitsa kuti ikhale yoyenera kugwiritsa ntchito izi.

Kodi chithandizo cha kutentha kwa molybdenum ndi chiyani?

Chithandizo cha kutentha kwa molybdenum nthawi zambiri chimaphatikizapo njira zomwe zimasintha makina ake monga ductility, kulimba, ndi mphamvu. Njira zodziwika bwino zochizira kutentha kwa molybdenum ndikuchepetsa komanso kuchepetsa nkhawa:

1. Annealing: Molybdenum nthawi zambiri imatsekeredwa kuti ichepetse kuuma kwake ndikuwonjezera ductility. Kutentha kwa molybdenum nthawi zambiri kumaphatikizapo kutentha kwapadera (nthawi zambiri pafupifupi 1200-1400 ° C) ndiyeno kuziziritsa pang'onopang'ono mpaka kutentha. Izi zimathandizira kuthetsa kupsinjika kwamkati ndikubwezeretsanso mawonekedwe a molybdenum, kukonza ductility ndi kulimba.

2. Kuchepetsa kupsinjika: Ziwalo za Molybdenum zomwe zakhala zikugwira ntchito kuzizira kwambiri kapena kupanga makina zimatha kuchepetsa nkhawa kuti muchepetse kupsinjika kwamkati ndikuwongolera kukhazikika kwa mawonekedwe. Njirayi imaphatikizapo kutenthetsa molybdenum ku kutentha kwina (nthawi zambiri pafupifupi 800-1100 ° C) ndikuisunga pa kutentha kumeneko kwa nthawi yochepa isanaziziritse pang'onopang'ono. Kuchepetsa kupsinjika kumathandizira kuchepetsa kupotoza ndikuchepetsa chiopsezo cha kusweka kwa zigawo za molybdenum.

Ndikoyenera kudziwa kuti njira yochizira kutentha kwa molybdenum imatha kusiyanasiyana kutengera kapangidwe ka aloyi, kugwiritsa ntchito komanso zomwe mukufuna. Choncho, tikulimbikitsidwa kukaonana ndi katswiri wa zipangizo kapena kutchula ndondomeko ya chithandizo cha kutentha kwa molybdenum kuti mutsimikizire chithandizo choyenera cha ntchito yomwe mwapatsidwa.

Kodi kutentha kwa molybdenum ndi chiyani?

Kutentha kwa molybdenum kumaphatikizapo kuphatikizira ufa wa molybdenum ndikuutenthetsa mpaka kutentha pansi pa malo ake osungunuka, zomwe zimapangitsa kuti tinthu tating'ono timene tigwirizane. Izi zimapangitsa kuti pakhale mawonekedwe olimba a molybdenum okhala ndi mphamvu komanso kachulukidwe.

Njira ya sintering nthawi zambiri imakhala ndi izi:

1. Kupondereza ufa: Gwiritsani ntchito nkhungu kapena kufa kuti musindikize ufa wa molybdenum mu mawonekedwe omwe mukufuna. Njira yophatikizira imathandiza kupanga mapangidwe ogwirizana kukhala ufa.

2. Kutentha: Ufa wopangidwa ndi molybdenum umatenthedwa mumlengalenga wolamulidwa mpaka kutentha pansi pa malo osungunuka a molybdenum. Kutentha kumeneku kumakhala kokwanira kuti tinthu tating'ono ting'onoting'ono tigwirizane ndi kufalikira, kupanga cholimba.

3. Kachulukidwe: Pa sintering ndondomeko, molybdenum dongosolo densifies monga munthu particles chomangira pamodzi. Izi zimapangitsa kuti kachulukidwe ndi mphamvu za sintered molybdenum zitheke.

Sintering nthawi zambiri imagwiritsidwa ntchito popanga zigawo za molybdenum zokhala ndi mawonekedwe ovuta komanso zofunikira zolimba kwambiri, monga zinthu zotenthetsera, zida za ng'anjo, mabwato a sintering, ndi zina zotere. Njirayi imapanga magawo amphamvu komanso olimba a molybdenum omwe ali ndi zida zamakina zotsogola zoyenera kugwiritsa ntchito kutentha kwambiri.
