SmCo maginito

SmCo maginito ali m'badwo wachiwiri wa osowa lapansi  maginito okhazikika , ndi mkulu-mphamvu okhazikika maginito anapangidwa kuchokera SM, Co, Fe ndi zinthu zina kufufuza zitsulo. Pambali Max ntchito kutentha kwa 300 ℃, lili kukana chidwi ndi dzimbiri ndi makutidwe ndi okosijeni. Chotero, mwina ntchito mu aeronautic ndi danga mafakitale aomng ena.

Manufactures  SmCo5  ndi  Sm2Co17  maginito mosiyanasiyana. Makasitomala ambiri amafuna sukulu YXG28, YXG30, YXG32, SmCo28, SmCo30, SmCo32, etc.

Machining ndi tolerances

Ife kukwaniritsa ooneka enieni kukula ndi kulolerana ndi kudula kapena akupera ndi abrasives wapamwamba. Samarium Cobalt (SmCo) sangakhoze kuuluka ndi kuboola ochiritsira, kutembenuzira kapena mphero njira, ndipo ayenera machined asanankhime maginito. Komanso, misonkhano yaikulu kapena zovuta zambiri nyese isanafike msonkhano. Standard tolerances kwa Samarium maginito Cobalt ndi +/-. 005 "chifukwa miyeso pansi. Ife amasunga maginito SmCo mu chipika, mphete ndi mawonekedwe chimbale zosiyanasiyana zamitundu ndi sukulu, ndipo ife okonzeka kuti apange kukula ndi kulolerana kuti amafuna.

zakuthupi 5 aloyi: 1

1: 5 amapereka 16 MGOe (mphamvu mankhwala) 22 MGOe ndipo wapangidwa pafupifupi 50% samarium ndi 50% cobalt. 1: 5 mndandanda ali pazipita analimbikitsa opaleshoni kutentha kwa 250 ° C. SmCo 1: 5 maginito amafuna m'munsi mphamvu kumunda katundu 2:17 kuti magnetize. Nthawi zina 1:15 chuma akhoza nyese ndi mitengo angapo, malinga ndi fixture magnetizing lilipo.

zakuthupi 2:17 aloyi

2:17 amapereka 24 MGOe kuti 32 MGOe ndipo wapangidwa ndi pafupifupi 25% samarium, 5% mkuwa, 18% chitsulo, 2% hafnium kapena zirconium, ndi yotsala kukhala cobalt. The 2:17 angapo ali pazipita opaleshoni kutentha kwa 350 ° C. sukulu Special wa 2:17 zilipo amene akhoza kugwira ntchito ngakhale apamwamba kutentha. SmCo 2:17 amafuna minda kwambiri mkulu magnetizing, ndipo angapo mzati magnetization sizingatheke.

3. Chifukwa mtengo tilinazo cobalt, mtengo wake ndi wokwera mtengo ndi zovuta kwanthawi

Kupanga ndondomeko Samarium Cobalt Permanent maginito: 
ufa ndondomeko → tikule → Sintering → Maginito katundu mayeso → kudula → yomalizidwa mankhwala
Samarium cobalt zipangizo ambiri kukonzedwa m'mikhalidwe zosagwiritsidwa nyese, ndi diamondi akupera gudumu ndi yonyowa zabwino umapezeka chimene chili chofunika. Chifukwa cha kutentha otsika poyatsira, samarium cobalt ayenera kukhala mouma. Monga ngati nthethe yaing'ono kapena magetsi malo amodzi kupanga mosavuta hule moto, ndi kutentha kwambiri Kumwambamwamba, amene ali kuugwira. 

Main Zoopsa: 
Samarium cobalt maginito ndi Chimaona. Chonde mokoma kuteteza maso anu, zala ndi thupi pamene nawo.

SmCo maginito vs Sintered Neodymium maginito
kusiyana pakati maginito SmCo ndi maginito Sintered NdFeB makamaka monga mfundo zotsatirazi:
1. Maginito mphamvu
Neodymium okhazikika maginito    ndi wamphamvu kwambiri kuposa SmCo maginito mu mphamvu ya maginito.
(Bh) Max wa NdFeB sintered ndi kuti 53MGOe, pamene (bh) Max wa SmCo zakuthupi 32MGOe.
SmCo zakuthupi mphamvu kukana demagnetization kuposa NdFeb zakuthupi.
2. Mkulu kutentha kukana
NdFeB si wapamwamba monga SmCo kutentha kukana mkulu. The pazipita ntchito kutentha kwa NdFeB ndi 200 ℃ ndi wa SmCo ndi ku 350 ℃.
3. dzimbiri kukana
NdFeB maginito si bwino kukana makutidwe ndi okosijeni ndi dzimbiri. Nthawi zambiri iwo ndi kutetezedwa ndi plating kapena ngakhale zingalowe wazolongedza. Mitundu wamba ❖ kuyanika monga nthaka, faifi tambala, epoxy ndi ena. SmCo maginito sati rusting popanda plating.
4. Chojambula, processing kusonkhana
NdFeb ndi SmCo ali osauka zosalimba, kotero iwo sangakhoze chopangidwa ndi wamba kudula processing.
The processing njira ambiri waya-elekitirodi kudula ndi diamondi gudumu kudula. Choncho akalumikidzidwa producible a maginito izi n'zochepa. Akalumikidzidwa n'zovuta si chopindulitsa. Ndi kulankhula, SmCo zakuthupi lofooka ndipo mosavuta kusiya. Choncho, chonde samalani kwambiri kusonkhana ndi ntchito SmCo maginito.
5. Price
Zaka zingapo zapitazo, mtengo wa maginito SmCo anali kawiri kapena kuposa maginito NdFeB.
M'zaka zaposachedwapa, mtengo wa NdFeB wauka kwambiri chifukwa miyeso kutipanikiza Dziko ku migodi osowa-lapansi. Kwenikweni, maginito wamba NdFeB ndi mtengo kuposa samarium cobalt.
