Ultra High Temperature SmCo Magnet

Kev tshawb fawb hotspot ntawm Samarium Cobalt hlau nplaum suav nrog kev ua haujlwm siab SmCo hlau nplaum, kub them nyiaj SmCo hlau nplaum, thiab ultra kub SmCo hlau nplaum. Thawj qhov sib txawv ntawm qhov kub thiab txias SmCo hlau nplaum thiab cov pa Sm (Co, Cu, Fe, Zr)_zCov hlau nplaum yog cov ntsiab lus ntawm Samarium, Cobalt, thiab Hlau. Cov_HcjTus nqi ntawm cov pa Sm (Co, Cu, Fe, Zr)_zCov hlau nplaum kuj yog siab heev, ces coercivity poob sai heev nrog nce kub thiab siab tshaj plaws ua hauj lwm kub T_wtsuas yog 300 degrees Celsius xwb. Thaum tshav kub kub kub SmCo hlau nplaum yog ib hom hlau nplaum ruaj khov nrog qhov kub thiab txias coefficient ntawm intrinsic coercivity._Hcj. Nws yog tsim los ntawm kev kho qhov muaj pes tsawg leeg thiab cov txheej txheem tsis sib xws ntawm cov pa Sm (Co, Cu, Fe, Zr)_zhlau nplaum.

Thermal stability ntawm cov hlau nplaum ruaj khov yog qhov tseem ceeb uas muaj ob lub ntsiab lus. Qhov thib ib yog kub coefficient ntawm remanence_Bryuav tsum muaj tsawg txaus tus nqi, ces sib nqus flux hloov me ntsis nyob rau hauv qhov ntau ntawm chav tsev kub thiab kub. Lwm lub ntsiab lus yog irreversible flux poob ntawm qhib Circuit Court yuav tsum tsawg txaus. T_wyog subordinate rau qhov thib ob txhais uas thov hlau nplaum muaj siab txaus chav tsev kub intrinsic coercivity Hcj thiab tsawg_Hcj. Qhov sib xyaw ua ke ntawm ob qhov kev ntsuas no tuaj yeem ua rau Hcj tswj hwm tus nqi siab dua nyob rau hauv qhov kub thiab txias thiab yog li zam lub hauv caug taw tes tshwm nyob rau hauv lub thib ob quadrant. Ib txoj kab ncaj nraim BH hauv qhov thib ob quadrant yog qhov tseem ceeb rau txhua qhov kev siv dynamic, tshwj xeeb tshaj yog cov motors. Ntau cov kev tshawb fawb tau qhia tias txo qis tus nqi ntawm_Hcjtuaj yeem txhim kho T_wzoo nyob rau hauv kev sib piv nrog rau kev txhim kho chav tsev kub Hcj thaum muaj pes tsawg leeg yog txiav txim siab. Cov kev tshawb fawb kuj tau qhia_Hcjyog hais txog qhov dimension ntawm cellular qauv hauv Sm₂(Cu, Cu, Fe, Zr)₁₇. Cov_Hcjtus nqi txo nrog kev txo qis ntawm cov qauv cellular qhov ntev. Qhov siab dua cov ntsiab lus ntawm Samarium thiab Cobalt, qhov ntau Sm (Co, Cu)₅cell ciam theem, yog li muaj txiaj ntsig los tsim cov qauv cellular zoo thiab txo qhov kub coefficient ntawm intrinsic coercivity. Rau qhov kub siab tshaj plaws SmCo hlau nplaum, BH nkhaus nyob rau hauv tag nrho cov kub ntawm 25 mus rau 550 degrees Celsius yog qhia raws li kab tsis muaj lub hauv caug taw tes. SDM twb tau paub ntau lawm ntau lawm ntawm ultra high kub SmCo hlau nplaum los ntawm optimizing multi-theem kev kho cua sov txheej txheem thiab tsim optimum cellular qauv.
