Magnari ya Samarium - cobalt ni rukuruzi idasanzwe-yisi, ikozwe muri samariyumu, cobalt nibindi bikoresho byisi bidasanzwe bikoreshwa mubutaka. Yatunganijwe neza mu 1970.Samariyumu - cobalt magnet ni magneti ya kabiri akomeye muri iki gihe, hamwe n’ibicuruzwa bitanga ingufu za magneti nyinshi (BHmax), imbaraga nyinshi, gucika intege no gucika. Ingufu ntarengwa zikoreshwa na magnetiki ya Samarium - cobalt magnet iri hagati ya 9 MGOe kugeza 31 MGOe. Magneti ya Samarium - cobalt ifite ibipimo bibiri bigize ibice, aribyo (atom samarium: atom cobalt) 1: 5 na 2:17. Kurugero, ingufu za magnetique ntarengwa ya 2:17 alloy ni 26 MGOe, agahato ni 9750 oersted, ubushyuhe bwa Curie ni 825 ° C, nubushyuhe bwo hejuru bukora ni 350 ° C.

Ibiranga ibiranga:
1. Guhatira cyane.
2. Ubushyuhe bwiza.
3. Igiciro kirazimvye kandi kirashobora guhindagurika kw'ibiciro (sensibilité ku isoko rya cobalt).

Ibyago nyamukuru:
1. Magnet ya Samarium - cobalt iroroshye gukuramo. Mugihe ubikemura, indorerwamo zigomba kwambara.
2. Kugongana kwa magnesi hamwe bishobora gutera magnesi kumeneka, bishobora gutera ingaruka mbi.
3. Gukora cobalt ya Samarium bikorwa nuburyo bwitwa sintering, burimo gucumura ibikoresho byose, kandi ibice byimbere birashoboka cyane. Magnets ntabwo zifite ubunyangamugayo kandi zifite umurimo wo gutegura imirima ya rukuruzi. Niyo mpamvu, birakenewe gushushanya sisitemu yihariye yubukanishi kugirango itange sisitemu rusange yizewe ihagije.
