Samarium Cobalt Cov Khoom Siv Hlau Nplaum



Hauj lwm

Raws li ib feem ntawm lub ntiaj teb tsis tshua muaj pawg ntawm cov hlau nplaum tas mus li, samarium cobalt (SmCo) hlau nplaum feem ntau poob rau hauv ob tsev neeg ntawm cov ntaub ntawv. Lawv suav nrog cov khoom ntiaj teb tsis tshua zoo Sm1Co5 thiab Sm2Co17 thiab raug xa mus ua 1: 5 thiab 2:17 cov ntaub ntawv. Muaj peb yam txheej txheem tsim khoom sib txawv: sintered SmCo hlau nplaum, sib tsoo SmCo hlau nplaum, thiab txhaj tshuaj SmCo hlau nplaum. SmCo hlau nplaum yog qhov ua tau zoo, tsis tshua muaj kev kub hloov coefficient ruaj khov ua los ntawm samarium thiab cobalt thiab lwm yam khoom ntiaj teb. Nws qhov txiaj ntsig loj tshaj yog kev ua haujlwm siab-300 degree centigrade. Nws yuav tsum muaj kev tiv thaiv vim tias nws nyuaj rau yaig thiab oxidized. SmCo hlau nplaum yog dav siv hauv lub cev muaj zog, saib, hloov pauv, ntsuas, ntsuas lub cev, lub tshuab hluav taws xob, radar, thiab lwm yam

Samarium Cobalt tuav nws cov cuab yeej txheem hauv qhov kub siab tshaj qhov siab tshaj li neodymium, txawm hais tias nws qhov siab tshaj plaws yuav tsawg dua. Tus nqi ntawm SmCo cov khoom siv yog qhov kim tshaj plaws, yog li SmCo pom zoo tsuas yog thaum nws qhov kev ua tau zoo yog qhov kub kub ib puag ncig yog kev txhawj xeeb.

1.SmCo cov hlau nplaum ruaj khov muaj lub zog nqus cov khoom siv hluav taws xob thiab muaj zog sib zog. Nws cov khoom tau zoo dua li Alnico, ferrite cov hlau nplaum ruaj khov. Nws cov max. lub zog khoom yog nce mus txog 239kJ / m3 (30MGOe), uas yog peb zaug ntawm AlNiCo8 cov hlau nplaum ruaj khov, yim lub sij hawm ntawd ntawm ferrite haujlwm ruaj nrees hlau nplaum (Y40). Yog li cov ntawv ruaj khov ruaj khov ua los ntawm SmCo cov khoom yog me me, lub teeb thiab ruaj khov hauv cov cuab yeej. Nws yog dav siv rau hluav taws xob acoustic & kev sib txuas lus hauv lub xov tooj, lub tshuab hluav taws xob, ntsuas kev ntsuas, peg sab saum toj hluav taws xob saib, microwave apparatus, sib nqus mechanism, sensor thiab lwm txoj kev zoo li qub lossis sib nqus.

2.Qhov lub cauj temp. ntawm SmCo cov hlau nplaum ruaj khov yog qhov loj thiab nws temp. Tub Cib. nyob qes. Yog li nws tsim nyog rau siv ntawm 300, temp siab.

3.SmCo cov hlau nplaum ruaj khov yog hnov ​​lus thiab xeb. Nws lub zog rigidity, lub zog tensile thiab nias lub zog yog tsawg. Yog li nws tsis haum rau lub moj khaum.

4.Cov khoom tseem ceeb ntawm SmCo cov hlau nplaum ruaj khov yog hlau cob (CoY99.95%). Yog li nws tus nqi yog siab.


Kev Tshaj Loj:
Cov yam ntxwv ntawm Samarium Cobalt Magnet

* Heev cov hlau nplaum muaj zog nrog zoo stability.
* Superior tsis kam mus rau qhov siab kub, Curie kub ntawm feem ntau yog tshaj 800 ?? * Zoo heev tiv taus corrosion, tsis muaj txheej xav tau rau kev tiv thaiv saum npoo.
