Samarium Cobalt Magnets yog dab tsi?

Taw qhia hauv xyoo 1970, samarium cobalt hlau nplaum yog thawj cov khoom lag luam muaj tsawg hauv ntiaj teb hlau nplaum. Lawv qhov kev taw qhia yog kev hloov pauv, triple lub zog loj tshaj plaws ntawm lwm cov hlau nplaum thaum lub sijhawm. Ua ntej kev taw qhia ntawm samarium cobalt hlau nplaum, tus qauv ntawm cov khoom sib nqus yog AlNiCo hlau nplaum. Samarium cobalt hlau nplaum yog cov hlau nplaum uas muaj zog tshaj plaws kom txog rau thaum lawv cov nqi ntau lawm tau ua rau cov kws ua haujlwm nrhiav pheej yig dua thiab tsim cov hlau nplaum neodymium, uas tam sim no yog cov hlau nplaum muaj zog tshaj plaws hauv ntiaj teb.

Cov qib feem ntau siv ntawm samarium cobalt hlau nplaum yog tsim los ntawm cov hlau nplaum ntawm kwv yees li 35 feem pua ​​(Sm) thiab 60 feem pua ​​(Co) nrog me me ntawm hlau (Fe), tooj liab (Cu), (Hf), (Z) thiab praseodymium (Pr). Qee qib ntawm samarium cobalt hlau nplaum yog tsim los ntawm samarium thiab cobalt, uas muaj kev tiv thaiv corrosion zoo heev.

Kub

SmCo Magnets belongs rau lub ntiaj teb tsis tshua muaj cov hlau nplaum ruaj khov xws li NdFeB hlau nplaum. Thaum lawv tsis muaj zog npaum li cov hlau nplaum neodymium, lawv muaj ob qhov zoo ntawm cov hlau nplaum neodymium. Lawv nyob hauv qhov kub thiab txias ntau dua thiab tiv taus corrosion. Thiab los ntawm 150 degrees Celsius, nws yuav zoo dua li NdFeB hlau nplaum nrog kub tsis kam. Feem ntau, qhov siab tshaj plaws ua haujlwm ntawm cov hlau nplaum NdFeB zoo tib yam tsuas yog 80 degrees Celsius. Yog li ntawd, nyob rau hauv ib puag ncig kub los yog kev siv, samarium cobalt hlau nplaum kuj yog ib qho kev xaiv zoo.

Tsis tsuas yog ua cov hlau nplaum samarium cobalt ua tau zoo ntawm qhov kub thiab txias, tab sis lawv khaws lawv cov hlau nplaum txawm tias qhov kub thiab txias qis dua ({0}} degrees Celsius), ua rau lawv nrov rau cov ntawv thov cryogenic.

Corrosion Resistant

Txij li feem ntau qib ntawm samarium cobalt hlau nplaum muaj me me los yog tsis muaj hlau, uas ua rau lawv zoo heev corrosion kuj, neodymium hlau nplaum feem ntau muaj 60-75 feem pua ​​hlau. Yog li ntawd, SmCo hlau nplaum feem ntau tsis tas yuav electroplating.

Cov khoom sib nqus

Piv nrog NdFeB hlau nplaum, cov khoom sib nqus tsis zoo li SmCo hlau nplaum, tab sis lawv muaj zog dua li cov ferrites zoo tib yam, sib npaug rau qib qis NdFeB hlau nplaum.

Pmov

Qhov tsis zoo ntawm samarium cobalt hlau nplaum yog tias lawv kim piv rau cov hlau nplaum neodymium vim yog tus nqi tsim khoom samarium. Zoo li lwm cov hlau nplaum hauv ntiaj teb tsis tshua muaj, lawv kuj yog cov nkig heev thiab yog li zoo tshaj plaws rau cov ntawv thov uas tsis tas yuav muaj kev cuam tshuam ncaj qha.

Adaim ntawv thov

Vim lawv cov khoom, cov hlau nplaum samarium cobalt feem ntau yog siv rau hauv cov ntawv thov uas yuav tsum tau ua haujlwm kub xws li cov tshuab hluav taws xob, twj tso kua mis txuas, sensors, hluav taws xob motors, marine daim ntawv thov nrog rau tsheb, aerospace, tub rog, khoom noj khoom haus thiab kev tsim khoom.
