Lub Hnub Qub Lub Hlis Cov Khoom Siv - HyMu 80 Permalloy Soft Magnet Alloy

Kev xa khoom raws li txoj cai

 

Niaj hnub no, peb yuav delve rau hauv kev ua lag luam thiab tshuaj xyuas yav dhau los cov neeg siv khoom xaj los tshawb txog tag nrho cov ntaub ntawv hais txog HyMu 80 (permalloy), siab -kev ua tau zoo ntawm cov hlau nplaum sib nqus.

 

Hauv kev ua haujlwm ntawm precision electronics, aerospace, thiab high -kawg instrument manufacturing, cov khoom sib nqus ntawm cov ntaub ntawv feem ntau txiav txim siab qhov rhiab heev thiab ruaj khov ntawm cov khoom tseem ceeb. HyMu 80 alloy, ib tug classic npib tsib xee- hlau- molybdenum mos magnetic alloy, tuav ib tug irreplaceable txoj hauj lwm vim nws tsis tshua muaj siab pib permeability thiab tsis tshua muaj coercivity.

 

Tom ntej no, kuv yuav qhia qee qhov kev txwv nrog HyMu 80 alloy, vam tias yuav pab tau ntau tus neeg siv uas xav paub txog thiab yuav HyMu 80 alloy.

 

Ntau-npe thiab cov qauv kev lag luam

 

Raws li peb nkag siab nws, HyMu 80 muaj ntau yam zoo -paub "tus kheej" nyob rau hauv kev lag luam, nrog rau cov khoom sib txawv ntawm lub npe cov rooj sib tham thoob plaws ntau lub teb chaws. Piv txwv li, nws belongs rau Permalloy tsev neeg thiab, vim nws kwv yees li 80% npib tsib xee cov ntsiab lus, feem ntau hu ua Permalloy 80. Nyob rau hauv cov nqe lus ntawm kev xaiv, nws sib raug rau cov khoom qhia los ntawm MAG7904 thiab US tub rog qauv MIL N-14411C Comp.1. Tsis tas li ntawd, Suav cov khoom siv hauv tsev tsim tawm 1J85 yog qhov zoo sib xws hauv kev muaj pes tsawg leeg thiab kev ua tau zoo thiab feem ntau yog siv los ua kev siv rau kev siv hauv tsev.

 

Hais txog cov qauv, HyMu 80 alloy feem ntau ua raws li ASTM A753-78 (American Society for Testing and Materials) thiab ASTM F15, ntawm lwm cov qauv. Cov qauv no qhia meej cov cai rau cov khoom siv hlau nplaum, tshuaj muaj pes tsawg leeg, thiab cov txheej txheem kho cua sov.

 

Cov neeg xaj xaj

 

 

Cov khoom siv hloov khoom daws teeb meem

 

Nrog rau kev txhim kho thev naus laus zis thiab kev xav txog tus nqi, qee cov khoom siv hloov pauv tau tshwm sim hauv khw, xws li 1J85 thiab permalloy 1J79.

 

Cov txheej txheem tsis raug thiab kev xav txog kev yuav khoom

 

Txawm hais tias nws qhov kev ua tau zoo heev, cov khoom siv ntawm HyMu 80 kuj nthuav qhia qee qhov kev sib tw ua haujlwm. Kev tawm tswv yim los ntawm Lork Group cov khoom siv sab hauv thiab kev ua lag luam thiab cov neeg ua haujlwm qhia tau hais tias cov ntsiab lus hauv qab no yuav tsum tau saib xyuas tshwj xeeb:

 

Kev kho cua sov rhiab heev: Cov khoom sib nqus ntawm HyMu 80 yog nyob ntawm cov txheej txheem kho cua sov kawg. Nws yuav tsum tau annealed rau ncua sij hawm ntawm 1000℃-1200℃nyob rau hauv ib tug ntshiab hydrogen los yog siab nqus cua kom txo tau kev ntxhov siab thiab optimize grain orientation. Kev kho cua sov tsis zoo yuav txo qis nws qhov sib nqus permeability, txawm tias qhov tsis zoo rau cov hlau silicon hlau. Yog li ntawd, qhov kev poob ntawm cov khoom siv no yog siab, tus nqi qis qis, thiab cov khoom siv yog 4-9 npaug siab dua li cov khoom sib nqus dav dav.

 

Impurity Sensitivity: Cov khoom yog qhov tsis tshua muaj siab rau impurities xws li carbon, sulfur, thiab phosphorus. Txawm tias muaj pes tsawg tus ntawm impurities tuaj yeem ua rau muaj kev sib txuam thiab ua rau cov khoom sib nqus tsis zoo. Yog li ntawd, lub tshuab nqus tsev melting yog ib qho tseem ceeb ua ntej kom ntseeg tau cov khoom purity. Rau peb txoj kev paub, tsuas muaj 5-10 lub Hoobkas hauv Suav teb nrog cov khoom tsim nyog thiab cov txheej txheem rau lub tshuab nqus tsev.

 

Ua hauj lwm hardening: Thaum lub sij hawm ua hauj lwm txias (xws li txias txias rau hauv cov hlab), cov khoom hardens sai heev, uas tsis tsuas yog ua rau kom nyuaj ntawm kev ua tab sis kuj ua rau nws cov khoom sib nqus. Yog li ntawd, cov neeg siv yuav tsum qhia seb yuav yuav HyMu 80 alloy nyob rau hauv lub "annealed xeev" los yog "lub xeev nyuaj".
