SmCo Igwe Ọdụdọ
Nkọwa dị mkpirikpi:
Igwe Igwe Igwe Ọdụdọ na-emepe emepe SmCo magnet ruo ọtụtụ afọ ma nwee nghọta miri emi nke sayensị akụrụngwa na teknụzụ injinịa. Nke a na-enyere anyị aka chepụta magnetik SmCo kacha dabara adaba wee mepụta uru maka ndị ahịa.
A na-egosi isi ngwaahịa samarium-cobalt, nke ike Magnet mepụtara dị ka ndị a:
Magnet 1:SmCo5 (1:5 18-22)
Magnet 2:Sm2Co17 (H usoro Sm2Co17)
Magnet 3:High okpomọkụ eguzogide Sm2Co17 (T usoro Sm2Co17, T350-T550)
Magnet 4:Okpomọkụ akwụ ụgwọ Sm2Co17(L usoro Sm2Co17, L16-L26)
A na-eji ngwaahịa samarium cobalt nke ike Magnet mee ihe na:
Moto dị elu (10,000 rpm+)
Ngwa na akụrụngwa ahụike,
Ụgbọ okporo ígwè
Nzikọrịta ozi
Nnyocha sayensị
H usoro Sm2Co17
T usoro Sm2Co17
L usoro Sm2Co17
Ihe mejupụtara na njikwa microstructure bụ isi ihe dị na mmepụta magnet cobalt samarium ma chọpụta njirimara magnetik. N'ihi ọdịdị na-abụghị ọkọlọtọ, ndidi na ọdịdị nke samarium cobalt magnet dịkwa mkpa.
● Ni-dabeere mkpuchi nwere ike n'ụzọ dị irè melite ekwe ike nke Sm2Co17 ~ 50%
● Enwere ike itinye mkpuchi Ni-based ruo 350 ℃ iji meziwanye ọdịdị elu na nkwụsi ike ogologo oge.
● Enwere ike itinye mkpuchi nke dabeere na epoxy ruo 200 ℃ (obere oge) iji welie ihe ndị na-emepụta ihe, nguzogide corrosion, na ibelata eddy-ugbu a na iji gbochie ịrị elu okpomọkụ.
● Na ultra elu okpomọkụ 500 ℃ na ikuku, mmebi oyi akwa ga-emetụta magnetik Njirimara. MA ọ bụ mkpuchi nwere ike nke ọma melite ogologo oge kwụsie ike nke SmCo na 500 ℃
● N'ihi njirimara mkpuchi ya dị mma, mkpuchi OR nwere ike ibelata oge dị ugbu a ma gbochie ịrị elu okpomọkụ.
● Ndị enyi gburugburu ebe obibi.
