Hana ʻia ʻo Samarium Cobalt Magnet Sm2Co17

ʻike ʻia ʻo ia ʻo samarium cobalt magnet, samarium cobalt permanent magnet, samarium cobalt permanent magnet, rare earth cobalt permanent magnet, etc. , kaomi a me ka sintering. A hiki i 350 ℃, ʻaʻole i kaupalena ʻia ka mahana maikaʻi ʻole, ke piʻi ka mahana hana ma luna o 180 ℃, ʻoi aku ka kiʻekiʻe o kona kūpaʻa wela a me ke kūpaʻa kemika ma mua o nā mea magnet mau loa NdFeB.
ʻO kekahi o nā mea hoʻokalakupua mau loa o ka honua, aia ka nui o ʻelua mau ʻāpana: SmCo5 a me Sm2Co17.Large magnetic ikehu huahana, hilinaʻi coercivity a me ke kūpaʻa wela kiʻekiʻe. ʻO ia ka lua o ka hanauna o nā huahana honua laha.
ʻOi aku ka ikaika o ka Samarium cobalt magnet (SmCo) i ka anti-corrosion, rust-proof a me ka wela kiʻekiʻe ma mua o nā magnet NdFeB. Hoʻololi ʻia nā magnet SmCo e ka alloying, kahi e hoʻololi loa i ke ʻano o ke kaʻaahi kaʻa honua.
Loaʻa iā ia ke kūpaʻa corrosion ikaika a me ka pale oxidation; no laila ua hoʻohana nui ʻia i ka aerospace, pale a me ka ʻoihana koa, nā mīkini microwave, nā kamaʻilio, nā mea lapaʻau, nā mea kani, nā mika, nā ʻano mea hoʻoili magnetic like ʻole, nā mea ʻike, nā mea hana magnetic, nā motika, nā cranes magnetic E kali.
