Abstract

본 발명은 알니코계 영구자석을 제조하는 방법에 관한 것으로써, 목적하는 조성의 알니코계 합금분말을 직접일공정에 의한 급속냉각기술을 이용하여 제조함으로써 분쇄성 및 성형성이 양호하고 높은 소결밀도를 가지며, 자기특성이 뛰어난 소결형 알니코계 영구자석을 값싸고 단순한 공정으로 제조하는 방법을 제공하고자 하는데, 그 목적이 있다.
본 발명은 Al-Ni-Co-Fe 또는 Al-Ni-Fe를 주요성분으로 하는 알니코계 영구자석을 제조하는 방법에 있어서, 알니코계 합금을 급속냉각기술을 이용하여 6-40m/sec의 냉각회전체 속도로 냉각하여 미세결정질의 급냉형 분말로 제조한 후, 미세분말로 분쇄하고 성형한 다음, 1100~1350℃의 온도에서 0.5-4시간 소결한 후, 일관열처리 공정에 의하여 600-1000℃ 온도구간에서 1-15kOe의 외부자장을 부하하면서 자장중 열처리를 행한 다음, 또는 자장중 열처리 없이 소결후 바로 500~700℃의 온도에서 1-10시간 시효 열처리하여 알니코계 영구자석을 제조하는 방법을 그 요지로 한다.
