Khoom Taw Qhia
Permanent agnet alnico yog ib chav kawm ntawm tus nqi qis, txuas ntxiv tsis muaj zog hlau nplaum ua los ntawm cov ntsiab lus tseem ceeb thiab cov lej ntawm tooj liab thiab titanium. Ntau qib hlau nplaum muaj nyob rau hauv cov ntawv cam khwb cia thiab sintered. AlNiCo yog cov hlau nplaum anisotropic cam khwb cia nrog cov khoom siv hluav taws xob siab tshaj plaws thiab muaj kev sib koom tes siab. Directionally solidified castings undergo extensive machining kom ua tiav qhov kawg net zoo thiab muaj feem xyuam rau cov teeb meem uas yuav tsum tau re-machined los yog scrapped, ua rau cov nqi nce thiab cov khoom pov tseg. Kev siv cov hlau nplaum NiCo hauv cov hlau nplaum tas mus li yog qhov txwv vim tias lawv tsis tshua muaj zog rau demagnetization. Tsis tas li ntawd, cov hlau nplaum ruaj khov alnico yuav tsum muaj qhov loj dua los tsim cov hlau nplaum tib yam hauv cov pa sib txawv. Kev sim txo qis Co cov ntsiab lus tau sib tw los ntawm kev txo qis hauv kev sib nqus magnetization thiab coercivity, qhia qhov xav tau rau cov txheej txheem kev siv nyiaj txiag zoo. Kev tsim khoom ntxiv tuaj yeem siv los tsim AlNiCo pellets. Ntxiv nrog rau tag nrho lwm qhov zoo, kev tsim khoom ntxiv tso cai rau kev tswj hwm zoo ntawm cov nplej zoo nkauj, ua kom cov khoom siv isotropic thiab isotropic hauv AlNiCo pellets.
Cov khoom ntawmruaj khov hlau nplaum alnico
Cov hlau nplaum tas mus li alnico nthuav tawm ntau yam khoom tseem ceeb uas ua rau lawv haum rau ntau yam kev siv:
Lub zog sib nqus: Txawm hais tias tsis muaj zog npaum li cov hlau nplaum tsis tshua muaj hauv ntiaj teb xws li neodymium thiab samarium-cobalt, cov hlau nplaum ruaj khov alnico muaj cov khoom siv hluav taws xob sib nqus siab (cov khoom siv hluav taws xob siab tshaj plaws ntawm 5.5 txog 9 MGOe) thiab tuaj yeem tsim cov hlau nplaum muaj zog.
Kev ua haujlwm kub siab: Ib qho tseem ceeb tshaj plaws ntawm cov hlau nplaum ruaj khov alnico yog lawv qhov tshwj xeeb kub ruaj khov. Lawv tuaj yeem tiv taus kev ua haujlwm siab txog li 550 degree (1022 degree F) yam tsis muaj qhov ua tau zoo ntawm cov hlau nplaum, ua rau lawv haum rau cov ntawv thov kub qhov twg lwm hom hlau nplaum yuav ua tsis tiav.
Corrosion tsis kam: Alnico hlau nplaum pom zoo heev corrosion kuj thiab feem ntau tsis tas yuav muaj txheej txheej los yog kev kho mob, txo cov kev tu ncua thiab txhim kho lawv lub neej ntev.
Tsawg coercivity: Alnico hlau nplaum muaj coercivity kuj tsis tshua muaj, uas txhais tau hais tias lawv muaj kev cuam tshuam ntau rau demagnetization thaum raug rau sab nraud magnetic teb los yog kub hloov. Cov cuab yeej no ua rau lawv tsis haum rau cov ntawv thov uas muaj zog sab nraud magnetic teb tam sim no.
