  • Imagnethi yeFeCrCo

Inkcazelo emfutshane:

Iqale yavela ekuqaleni koo-1970, umazibuthe we-FeCrCo okanye i-Iron Chromium Cobalt umazibuthe yenziwe yi-Iron, iChromium, kunye ne-Cobalt. Inzuzo ebalulekileyo yeemagnethi ze-Fe-Cr-Co ngamaxabiso aphantsi okunokwenzeka okubunjwa.


Iinkcukacha zeMveliso

Iithegi zeMveliso

Izinto ezikrwada ziyi-vacuum melt kwi-alloy ingot, emva koko ii-ingots ze-alloy zinokutshintshwa ngokuqengqeleka okushushu, ukuqengqeleka okubandayo kunye nazo zonke iindlela zobuchule bokomba, ukujika, ukudinwa, njl.njl. ukubumba imagnethi ye-FeCrCo. Iimagnethi ze-FeCrCo zineempawu ezifanayo kunye nemagnethi ye-Alnico efana ne-Br ephezulu, i-Hc ephantsi, ubushushu obuphezulu bokusebenza, uzinzo oluhle lobushushu kunye nokuxhathisa umhlwa, njl.

Nangona kunjalo, iimagnethi ezisisigxina ze-FeCrCo zaziwa njengeenguqu kwiimagnethi ezisisigxina. Zilula ukusetyenzwa kwesinyithi, ngakumbi umzobo wocingo kunye nomzobo wetyhubhu. Le yinzuzo ukuba ezinye iimagnethi ezisisigxina azinakuthelekiswa nazo. I-alloys ze-FeCrCo zinokutshisa ngokulula kwaye zenziwe ngoomatshini. Akukho zithintelo kwiimilo kunye nobukhulu bazo. Zingenziwa kumacandelo amancinci kwaye antsokothileyo emilo efana nebhloko, ibha, ityhubhu, umcu, ucingo, njl njl. Ubuncinci babo bobukhulu bunokufikelela kwi-0.05mm kwaye ubukhulu be-thinnest bunokufikelela kwi-0.1mm, ngoko ke bafanele ukuveliswa kwe-high- amacandelo achanekileyo. Ubushushu obuphezulu beCurie bumalunga nama-680°C kwaye elona qondo lobushushu liphezulu lokusebenza linokuba phezulu ukuya kuma-400°C.
