Samarium kobalt halqa magniti, shuningdek, SmCo halqa magnit sifatida ham tanilgan, tez-tez ishlatiladigan magnit materialdir va uning kimyoviy tarkibi SmCo5 yoki Sm2Co17. SmCo magnitlari mukammal magnit xususiyatlarga ega, yuqori majburlash kuchi, oksidlanish qarshiligi va korroziyaga qarshilikka ega, shuning uchun ular elektr, elektron, kompyuter texnologiyalari, aerokosmik va boshqa sohalarda keng qo'llaniladi.
Samarium-kobalt halqa magnitlarini ishlab chiqarish jarayoni nisbatan murakkab va ishlab chiqarish jarayonida presslash va sinterlash kabi bir nechta jarayonlar talab etiladi. Samarium kobalt halqa magnitlari asosan ikki turga bo'linadi, ya'ni koaksiyal tip va split mil turi. Koaksiyal SmCo magnitlari ichki doira, ichki doira va tashqi doira va ichki doira, ichki doira va tashqi doiraga bo'linadi, bo'lingan eksa turi esa turli yo'nalishlarda magnitlangan ikkita magnitning birikmasini bildiradi.
Samarium kobalt halqa magnitlari, masalan, motorlar, generatorlar, kompyuterning qattiq diskini o'qish / yozish boshlari, antennalar, sensorlar, tibbiy asbob-uskunalar, aerokosmik va boshqa sohalarda keng qo'llaniladi. Samarium-kobalt halqa magnitlari barqaror magnit xususiyatlarga ega, korroziyaga chidamliligi, yuqori haroratga chidamliligi va radiatsiya qarshiligiga ega bo'lib, ularni yuqori samarali elektron qurilmalarni loyihalashda almashtirib bo'lmaydi.
Xususiyatlari
1, SmCo Ring Magnit yuqori magnit ko'rsatkichlarga ega (yuqori Br, Hcb & (BH) max), xona haroratida (BH) maksimal 35MGOe ga etadi, bu faqat NdFeB magnitidan past, lekin boshqa magnitlardan ancha yuqori.
2, SmCo magnitining ish harorati 550 darajaga yetishi mumkin, bu boshqa magnitlar orasida eng yuqori hisoblanadi.
3, SmCo magniti kuchli korroziyaga chidamlilik va oksidlanishga qarshi xususiyatlarga ega bo'lib, uzoq vaqt davomida ishlatilishi mumkin.
4, SmCo magniti juda past harorat koeffitsientiga ega, odatda -0,030 foiz /K.
