SmCo nā mākēneki

SmCo nā mākēneki i lua o ka hanauna o ka pohihihi keia honua  paʻa nā mākēneki , o ke kiʻekiʻe-naʻe paʻa Mākēneki i mai SM, Li, Fe a me nā kumumea metala hehee wale. Ma waho o ka max e hana ana i ka mahana o ka 300 ℃, ka mea, he mea kupaianaha e kū'ē'ē mai e ku e ia ka popopo a me ka'okesaside. Nolaila, ka mea hiki ke hoʻohana 'ia ma aeronautic a me ka makahiki hana aomng' ē aʻe.

Hana  SmCo5  a  Sm2Co17  nā mākēneki i loko o nā kinona. He nui nā mea mālama mai noi aku papa YXG28, YXG30, YXG32, SmCo28, SmCo30, SmCo32, etc.

Machining a me ke ahonui,

Mākou loaʻa iā dimensional nui a me ke ahonui, ma ka oki a wili me Naha Pōhaku abrasives. Samarium Cobalt (SmCo) hiki ole ke wili iʻike mauʻeli, haliu ae la ia a me ka mīkini wili pōhaku keʻano o ka hanaʻana, a me ka pono e mīkini penei: mua ka mea, e magnetized. Eia kekahi, nui a luna 'ekalesia i ana magnetized mamua i kaʻaha kanaka. Maʻamau ke ahonui, no ka Samarium Cobalt nā mākēneki i +/-. 005 "no ka lepo Ana. Mākou laau SmCo nā mākēneki ma ka aeie, komolima a me ka iwi kuamoʻo ano i loko o ka likeʻole ma o ka nui like 'ole a me nā papa, a mākou e maopopo iai? Oaiaaiea e paka i ka nui a me ka ioeeiiaiey ia oe he pono.

1: 5 oka mea

1: 5 kaumaha ana 16 MGOe (ikehu huahana) i 22 MGOe, a ua i mai o ka hola 50% samarium a me 50% cobalt. Ka 1: 5 moʻo i ka i kā mākou paipai pae'ōnaehana mahana o ka 250 ° C. SmCo 1: 5 nā mākēneki noi haʻahaʻa kahua ikaika ma mua o 2:17 mea e magnetize. I kekahi manawa, 1:15 lako e hiki e magnetized i mau auamo, aka i ka magnetizing fixture mea i loaʻa.

2:17 oka mea

2:17 kaumaha ana 24 MGOe i 32 MGOe a ua haku o ma kahi o 25% samarium, 5% keleawe, 18% hao, 2% hafnium a zirconium, a me ke koena i cobalt. Na 2:17 moʻo o ka mai i kā mākou pae'ōnaehana mahana o ka 350 ° C. Special papa o 2:17 i loaʻa i ae ke hana e like kiekie ana wela. SmCo 2:17 pono loa kiʻekiʻe magnetizing mahinaʻai, a me ka lau laau magnetization mea,ʻaʻole hiki.

SmCo nā mākēneki makou Sintered Neodymium nā mākēneki
ka oko ao ma waena o SmCo nā mākēneki a me Sintered NdFeB nā mākēnekiʻano nui loaʻa i ka penei kumu:
1.ʻume mākenēki ikaika
Neodymium paʻa Mākēneki    Ua oi loa aku kou mana ma mua o SmCo Mākēneki maʻume mākenēki ikaika.
(BH) Max o sintered NdFeB mea i ai i 53MGOe, oiai ka (BH) Max o SmCo mea o 32MGOe.
SmCo lako e ka ikaika i loko o ka pale aku demagnetization ma mua o NdFeb mea.
2. High wela ia'ku
NdFeB mea,ʻaʻole i oi like SmCo ma kiʻekiʻe ana wela e kū'ē'ē mai. ʻO kā mākou hana mahana o NdFeB He 200 ℃ a me ia o SmCo mea i ka 350 ℃.
3. ka popopo ia'ku
NdFeB nā mākēneki i ole ai e pono i ka pale aku'okesaside a me ka popopo. Nui ka mea, i ia e hoomaluia ma ka plating paha i holo hāʻawe. Common ano o ka penaʻana nā kiniki, nikala, pīlali a me na mea e ae. SmCo nā mākēneki e ole e rusting me plating.
4. kinona, aaioee a me ka houluulu
NdFeb a me SmCo nō nā fragile mea, no laila, ka mea hiki ole ke ua hanaʻia ia e maʻamau ana aaioee.
Ke mau aaioee iaoiaeii ka uea-'ūholo uila ana a me ka daimana huila ana. No laila, i ka producible kinona o kēia nā mākēneki i kaupalena. Po huikau kinona i ole workable. KŘpa a olelo ana, SmCo lako Ua oi fragile a loa ke puana mai hemo mai. No laila, e 'oluʻolu e loa makaala i ka'ākoakoa nui ana, a me ka hoʻohana' SmCo nā mākēneki.
5. Price
A mau makahiki aku nei, i ke kumu kūʻai o SmCo nā mākēneki ua palua paha i oi aku ia o NdFeB nā mākēneki.
Ma nā makahiki, ua ala ae nei ia nui i ke kumu kuai o NdFeB ma muli o ke Country ka restrictive ana ma ka pohihihi-honua hoʻouku. Holo nōhie, he pono ole NdFeB nā mākēneki e ho'ēmi ma mua o samarium cobalt.
