Kev piav qhiaNtawm Super Permanent StrongSamarium Cobalt Magnets
Samarium Cobalt SmCo yog lwm cov hlau nplaum tsis tshua muaj ntiaj teb. Nws yog feem ntau siv hauv aerospace, tsheb thiab kev siv tub rog. Nws feem ntau tsis muaj zog dua NdFeB Neodymium ntawm chav tsev kub. Samarium Cobalt SmCo muaj peev xwm siv tau nyob rau hauv huab cua txias thiab cua sov. Nws kuj muaj coercivity siab heev ua rau nws zoo tagnrho rau high-temperature motor applications.
Cov hlau nplaum Samarium Cobalt (SmCo) yog cov hlau nplaum muaj zograre ntiaj teb hlau nplaumyog tsim los ntawm samarium thiab cobalt. Lawv feem ntau yog siv nyob rau hauv high-kev ua tau zoo motors, sib nqus couplings, thiabSib nqus separators. Cov no yog cov hlau nplaum nkig thiab ua rau tawg thiab tawg. Samarium hlau nplaum tuaj yeem siv rau cov ntawv thov kub qhov twg neodymium yuav tsis ua haujlwm.

Muaj ob qhov sib xyaw ntawm cov hlau nplaum hauv tsev neeg no: Sm1Co5 thiab Sm2Co17. Cov khoom lag luam muaj zog tshaj plaws ntawm Sm2Co17 yog nyob rau hauv 30MGOe ntau yam. Samarium Cobalt SmCo hlau nplaum muaj nyob rau hauv ob hom alloy. Sm1Co5 (SmCo1: 5) yog thawj SmCo alloy. Sm2Co17 (SmCo2: 17) yog qhov siv ntau dua thiab muaj zog SmCo alloy nrog SmCo26 yog ntau yam nrov tshaj plaws. Sm1Co5 muaj feem ntau Sm thiab Co thiab tsis muaj hlau (Fe) yog li nws muaj kev tiv thaiv corrosion zoo heev. Sm2Co17 feem ntau yog Sm thiab Co tab sis kuj muaj Cu, Hf& / lossis Zr, qee zaum Pr, thiab Fe. Cov ntsiab lus tsis tshua muaj hlau tsis muaj nyob hauv Sm2Co17 txhais tau tias nws yog technically prone rau me ntsis nto corrosion thaum nyob rau hauv dej. Sm2Co17 suav hais tias yog qhov zoo rau kev tiv thaiv corrosion zoo heev (dhau zoo dua rau NdFeB) hauv ntau daim ntawv thov.
