Ihe ndi ozo Samarium Cobalt



Description

Dị ka akụkụ nke obere ụwa nke ihe ndọta na-adịgide adịgide, njupụta samarium cobalt (SmCo) na-adabakarị n'ezinụlọ abụọ nke ihe. Ha gụnyere obere ụwa Sm1Co5 na Sm2Co17 ma kpọọ ha ihe 1: 5 na 2:17. E nwere usoro nrụpụta atọ dị iche iche: igwe ndọta SmCo sintered, ndọta SmCo jikọtara ya, na ịkpụzi ọgwụ SmCo magnet. SmCo magnet bụ arụmọrụ dị elu, ọnụọgụ okpomọkụ dị ala na-adịgide adịgide nke samarium na cobalt na ihe ndị ọzọ dị obere. Ya nnukwu uru bụ elu na-arụ ọrụ okpomọkụ-300 ogo centigrade.

Samarium Cobalt na-ejide akụ ya ọkọlọtọ na ogo kachasị dị elu karịa neodymium, ọ bụ ezie na strengh ya kachasị obere. Ọnụahịa nke ihe SmCo bụ nke kachasị ọnụ, yabụ na-akwado SmCo naanị mgbe arụmọrụ ya bụ gburugburu ebe dị elu dị elu na-akpata nchegbu.
 
1.SmCo na-adịgide adịgide magnet nwere nnukwu magnetik ike ngwaahịa na elu coercive ike. Njirimara ya dị mma karịa Alnico, ferrite na-adịgide adịgide magnet. Ihe kachasị. ngwaahịa ike ruru 239kJ / m3 (30MGOe), nke bụ ugboro atọ nke nke AlNiCo8 magnet na-adịgide adịgide, ugboro asatọ nke nke magnet na-adịgide adịgide (Y40). Ya mere, magnetik na-adịgide adịgide mere site SmCo ihe onwunwe bụ obere, ìhè na mụ na ihe onwunwe.
