Qhov zoo thiab qhov tsis zoo ntawm Sm2Co17 thiab SmCo5 cov khoom sib nqus mus tas li

Piv nrog SmCo5, lubSm2Co17muaj qhov zoo hauv qab no:

1. Cov ntsiab lus ntawm cobalt thiab samarium nyob rau hauv cov mis ntawm Sm2Co17 mus tas li hlau nplaum khoom yog qis dua li ntawm SmCo5 mus tas li hlau nplaum khoom, uas zoo heev txuag tus nqi ntawm raw cov ntaub ntawv.Vim tias samarium thiab cobalt raw cov ntaub ntawv yog cov hlau tsis tshua muaj nqi, yog li tus nqi ntawm Sm2Co17 cov khoom siv hlau nplaum ruaj khov yog qis dua li ntawm SmCo5;

2. Qhov sib nqus induction kub coefficient ntawm Sm2Co17 cov khoom sib nqus ruaj khov yog li -0.02% / ℃, nws tuaj yeem ua haujlwm nyob rau hauv thaj tsam ntawm -60 ~ 350 ℃, uas yog incomparable rau SmCo5 mus tas li hlau nplaum khoom;

3.Curie kub yog siab.Curie point ntawm Sm2Co17 cov khoom yog hais txog 840 ~ 870 ℃, thiab Curie point ntawm cov khoom SmCo5 yog 750 ℃.Qhov no txhais tau hais tias Sm2Co17 tiv taus kub ntau dua li SmCo5.Txawm li cas los xij, piv nrog SmCo5 cov khoom siv hlau nplaum ruaj khov, cov txheej txheem tsim khoom ntawm Sm2Co17 yog qhov nyuaj dua.Txhawm rau txhim kho kev sib koom tes, nws yuav tsum muaj hnub nyoog rau ntau lub sijhawm, thiab cov txheej txheem nqi siab dua li ntawm SmCo5.Hauv cov hlau nplaum tas mus li, Sm2Co17 cov khoom sib nqus yog ib hom hlau nplaum ruaj khov uas muaj peev xwm ua haujlwm kub.

Vim tias qhov kev thov ntau ntxiv rau cov hlau nplaum ruaj khov siv siab dua 400 ℃ hauv kev lag luam aerospace thiab hluav taws xob, cov khoom siv hlau nplaum ruaj khov nrog cov kev pabcuam kub thiab kev ua haujlwm zoo heev tau txais tos los ntawm pej xeem.Txawm hais tias kev khiav hauj lwm kub ntawm Alnico mus tas li hlau nplaum yog siab dua 500 ℃, nws qhov kev coercivity qis dhau los ua kom tau raws li cov kev xav tau ntawm kev siv tswv yim.NdFeb tsis tshua muaj lub ntiaj teb cov hlau nplaum ruaj khov lub cev muaj zog coercivity thiab kev ua haujlwm zoo, tab sis kev siv kub tsis tuaj yeem ua tau raws li qhov xav tau saum toj no, vim Curie kub qis thiab kub coefficient loj.Vim nws txoj kev ua tau zoo heev, Sm2Co17 cov khoom siv hlau nplaum ruaj khov tau siv dav hauv lub cev muaj zog, ntsuas ntsuas, microwave, sensor, ntes thiab lwm yam khoom siv high-tech.
