Izakhiwo ze-Molybdenum lanthanum alloy: Uyini umehluko phakathi kwengxube ye-molybdenum lanthanum (Mo-La) ne-TZM molybdenum alloy?

Uyini umehluko phakathi kwengxubevange ye-molybdenum lanthanum (Mo-La) ne-TZM molybdenum alloy?

Iyini ingxubevange ye-molybdenum-lanthanum? Ingxubevange ye-Molybdenum-lanthanum iyingxubevange eyakhiwe ngesisekelo sensimbi ye-molybdenum ne-lanthanum trioxide ekhona njengezinhlayiya ezihlakazekile ku-matrix. Okuqukethwe kwe-La2O3 ku-alloy ngokuvamile kungu-0.5%~5.0% (ingxenyana yobuningi). Kuya

Ngocwaningo lokusebenza kwezinga lokushisa eliphezulu kanye nesakhiwo esihambisanayo se-molybdenum-lanthanum alloy ne-TZM alloy ku-1000~1800℃. Imiphumela ikhombisa ukuthi uma izinga lokushisa lingaphansi kuka-1400℃, ingxubevange ye-molybdenum-lanthanum inokusebenza okuphezulu okubanzi kwamandla nepulasitiki. Lapho izinga lokushisa lilikhulu noma lilingana no-1400℃, amandla okunyakazisa engxubevange ye-molybdenum-lanthanum ayancipha, kanye nepulasitiki yengxubevange ye-molybdenum-lanthanum nayo iyancipha. Ngokukhuphuka kwezinga lokushisa lokuhlola, amandla aqinile engxubevange ye-TZM ayancipha, kodwa ipulasitiki ye-TZM molybdenum alloy iyanda, okuphambene ncamashi nengxubevange ye-molybdenum-lanthanum.

Ngesikhathi esifanayo, kungakhathaliseki ukuthi amandla noma ipulasitiki, ingxube ye-TZM iqhathaniswa ne-molybdenum-lanthanum alloy ekushiseni okufanayo. Ukubuka kwe-Microstructure kukhombisa ukuthi lezi zingxubevange ezimbili ze-molybdenum ziqala ukuphinda zikhanye ku-1100 ℃ futhi ziqhubeke ziye ku-1550 ℃, futhi okusanhlamvu kwazo okuphinde kwakhiqizwe kabusha kubonisa ukwakheka okude, okuhlukile kuzinhlamvu ezilinganayo esimweni esiphinde sakhiwe kabusha se-molybdenum emsulwa.

1. Isingeniso se-molybdenum lanthanum alloy

I-Molybdenum lanthanum alloy, eyaziwa nangokuthi izinga lokushisa eliphezulu le-molybdenum, i-brand MoLa, yenziwe nge-molybdenum efakwe ngenani elincane lezinhlayiya ze-lanthanum trioxide (La2O3) ukwakha okuthiwa isakhiwo se-fiber laminated. Lesi sakhiwo esincane esikhethekile singahlala sizinzile ngisho nasemazingeni okushisa afinyelela ku-2000°C. Ngakho-ke, i-molybdenum-lanthanum oxide inokumelana nokukhasa ngisho nangaphansi kwezimo ezimbi kakhulu zokusetshenziswa. Ikakhulukazi sicubungula ama-alloys anjalo e-molybdenum ezingxenyeni zesithando somlilo esisezingeni eliphezulu, njengezihlangu zokushisa zesithando sevacuum, izikebhe ezishisayo nezifaka amanzi, izintambo eziboshiwe noma amakhoyili e-evaporator.

2. Izinzuzo ze-molybdenum lanthanum alloy:

Amazinga okushisa aphakeme ecrystallization;

Isakhiwo sezinhlayiya eside singathuthukisa i-ductility;

Ukumelana ne-oxidation okunamandla;

Ukumelana nokukhuphuka okuphezulu.

3. Izinga lokushisa lokuvuselela kabusha: 1400 ℃ ~ 1500 ℃.
