Samarium kobalt magniti noyob tuproqli doimiy magnit materialdir. Mijozlarning talablariga muvofiq, u mukammal xususiyatlarga ega bo'lgan turli shakldagi magnit komponentlarga ishlov berilishi mumkin. Samarium kobalti odatda SmCo5 va Sm2Co17 sifatida yozilgan 1:5 va 2:17 ikkita seriyani o'z ichiga oladi. Samarium kobalt magniti yaxshi magnit xususiyatlarga ega yuqori doimiy magnit materialdir. Kuchli korroziyaga chidamlilik, oksidlanishga chidamlilik, yuqori haroratga chidamlilik, yuqori haroratli ishlash va 350 darajaga qadar maksimal ish harorati.
SmCo Arc Magnet - bu SmCo Rare Earth magnitlarining keng tarqalgan shakli. SmCo Arc Magnitlari ayniqsa motorlar, generatorlar va alternatorlar uchun mo'ljallangan va odatda rotorlar va statorlar uchun ishlatiladi. Ular magnit volan majmualarida ham qo'llaniladi. SmCo Arc Magnitlari yuqori haroratli ilovalar uchun juda mos keladi, chunki ular 250-350 darajada to'g'ri ishlashi mumkin.

Samarium kobalt magnitlarini ishlab chiqarish jarayoni
SmCo magnitlari odatda chang metallurgiyasi yordamida ishlab chiqariladi. Qotishtiruvchi elementlar birinchi navbatda tez sovutilgan vakuumli induksion pechda eritiladi va keyin zarracha o'lchami 10 mkm dan kam bo'lguncha maydalanadi, bunda faqat monokristalli kukun mavjud. Keyin qotishma kukuni magnit maydonda hizalanadi va jarayonga qarab, bir vaqtning o'zida yashil kompaktga bosiladi. Shundan so'ng vakuumda yoki himoya gaz ostida zich sinterlash jarayoni amalga oshiriladi. Magnitlar issiqlik bilan ishlov berish jarayonida majburiy maydon kuchini oladi.
Qoplama turlari va ishlov berishning aniqligi
Samarium-kobalt magnitlari yaxshi korroziyaga chidamliligiga ega, ular xona haroratida qoplamasiz ishlatilishi mumkin. Shuningdek, u dastur va mijozning talablariga muvofiq sozlanishi mumkin.

Samarium kobalt magniti chang metallurgiyasi tomonidan ishlab chiqariladi, shuning uchun o'lchov xatolariga va deformatsiyaga duch kelishi muqarrar. Silliqlash zaruriy jarayondir.
