Lub La2O3 hais dispersed nyob rau hauv molybdenum-lanthanum alloy zoo heev txhim kho cov khoom alloy. Piv nrog cov ntshiab molybdenum, cov molybdenum-lanthanum alloy muaj ntau dua thermal electron emission kev ua tau zoo, tensile thiab dabtsi yog khoov tsis kam, zoo ductility thiab puas toughness, thiab zoo creep kuj. Muaj ntau yam uas cuam tshuam rau qhov kev ua tau zoo kawg ntawm molybdenum-lanthanum alloy, nrog rau cov ntsiab lus ntawm dopants, doping txheej txheem, sintering txheej txheem, deformation txheej txheem thiab kev kho cua sov txheej txheem. Ntawm lawv, qhov tsim nyog doping tus nqi (1%) tuaj yeem ua rau muaj txiaj ntsig zoo ntawm molybdenum alloy xws li lub zog thiab plasticity, tab sis thaum cov ntsiab lus siab dhau lawm, lub zog thiab elongation raug txo.
1. Alloy doping txheej txheem
Muaj peb txoj hauv kev tseem ceeb rau dope La2O3 hauv Mo metal.Solid-solid doping method: Molybdenum hmoov thiab La2O3 hmoov yog tov los ntawm pob milling, thiab tom qab ntawd nias thiab sintered los ua molybdenum alloy; Txoj kev ua kua-kua doping: Lanthanum nitrate yog txau rau hauv molybdenum oxide los ntawm atomization, qhuav thiab txo, thiab tom qab ntawd nias thiab sintered los ua molybdenum alloy; Txoj kev ua kua-kua doping: Ib qho tshuaj soluble lanthanum ntsev yog ntxiv rau molybdenum ntsev tov, thiab molybdenum alloy yog tsim los ntawm cov tshuaj tsuag kom qhuav, txo, nias thiab sintering. Cov txheej txheem doping sib txawv muaj lawv tus kheej cov yam ntxwv, ntawm cov uas molybdenum-lanthanum alloy npaj los ntawm cov kua-kua doping muaj kev ua tau zoo dua li ob txoj hauv kev.
2. Daim ntawv thov teb
Molybdenum-lanthanum alloy yog tam sim no siv dav hauv electronics, aerospace, nuclear zog, mechanical processing thiab lwm yam kev lag luam vim nws cov kev ua tau zoo heev. Hauv kev lag luam hluav taws xob, vim muaj cov yam ntxwv ntawm qhov muaj zog toughness, siab emissivity thiab tsis muaj kuab paug, molybdenum-lanthanum alloy tuaj yeem hloov cov khoom siv thorium-tungsten ua cov khoom siv cathode, daws qhov teeb meem loj ntawm cov pa phem ntawm cov tshuaj thorium-tungsten cathode tom qab kev npaj, ua thiab pov tseg; Nyob rau hauv lub tshav pob ntawm aerospace, molybdenum-lanthanum alloy raws li lub cav nozzle cov ntaub ntawv muaj zoo ablation kuj, tag nrho raws li cov kev cai siv lub sij hawm luv luv lub foob pob hluav taws cav, thiab tau siv nyob rau hauv batch; nyob rau hauv lub tshav pob ntawm mechanical processing.Molybdenum Lanthanum Wire hloov ntshiab molybdenum hlau raws li hluav taws xob spark hlau txiav electrode hlau, thiab nws cov kev pab cuam lub neej yog li ntawm 50% siab dua li cov ntshiab molybdenum hlau, uas yuav txuag tau nqi. Molybdenum-lanthanum alloy tseem tuaj yeem siv los ua cov cua kub cua kub cua sov, X-ray ncej phiaj, pwm, thiab lwm yam, uas yog qhov tseem ceeb heev rau kev nce qib thiab kev siv.
Peb lub tuam txhab tseem tuaj yeem muab lwm cov khoom lag luam molybdenum lanthanum alloy xws li Molybdenum Lanthanum Foil thiab Molybdenum Lanthanum Rod. Thov koj xav tiv tauj peb los ntawm email.
