Samarium–cobalt magnet ni magnet ya Rare-earth, ikozwe muri samarium, cobalt n'ibindi bikoresho by'icyuma bya rare earth binyuze mu guhuza. Yakozwe neza mu 1970. magnet ya Samarium–cobalt ni magnet ya kabiri ikomeye muri iki gihe, ifite ingufu nyinshi za magneti (BHmax), imbaraga nyinshi, ubushobozi bwo gucika no gucika. Ingufu nyinshi za magneti ya Samarium–cobalt magneti ziri hagati ya 9 MGOe na 31 MGOe. magneti ya Samarium–cobalt ifite imiterere ibiri, ari yo (atome ya samarium: atome ya cobalt) 1:5 na 2:17. Urugero, ingufu nyinshi za magneti za alloy 2:17 ni 26 MGOe, imbaraga ni 9750 oersted, ubushyuhe bwa Curie ni 825 ° C, n'ubushyuhe ntarengwa bwo gukora ni 350 ° C.

Ibiranga ibiranga:
1. Gukoresha imbaraga nyinshi cyane.
2. Ubushyuhe buhamye neza.
3. Igiciro kirahenze kandi gishobora guterwa n'ihindagurika ry'ibiciro (uburyo ibiciro by'isoko rya cobalt bihagaze).

Ibyago by'ingenzi:
1. Sukuru ya Samarium–cobalt yoroshye kuyikuraho. Mu kuyikoresha, ugomba kwambara amadarubindi.
2. Guhura kwa rukuruzi bishobora gutuma rukuruzi zicika, ibyo bikaba byateza ibyago bishobora kubaho.
3. Gukora Samarium cobalt bikorwa hakoreshejwe uburyo bwitwa sintering, bukubiyemo gutwika ibikoresho byose, kandi imyanda y'imbere ishobora kubaho cyane. Magnets ntabwo zifite ubuziranenge bwa mekanike kandi zifite akazi ko gutegura imbaraga za mekanike gusa. Kubwibyo, ni ngombwa gushushanya sisitemu zihariye za mekanike kugira ngo sisitemu yose ihabwe ubuziranenge buhagije bwa mekanike.
