Abstract

본 발명은 해면철 분말과 경질상 재료로 이루어진 미세하게 연마된 분말을 제조하기 위한 방법 및 이 방법에 의해서 만들어진 조성물을 제공하려는 것이다.

Description

해면철 분말(SPONGE-IRON POWDER)
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 밀링시간에 따른 분말 조성물의 입자크기 변화를 나타낸 그래프이다.

Claims (8)

  1. 80부피%에 달하는 경질상의 재료와 해면철로 이루어지고 연마과정 동안에 혼합되는 분말을 포함하는 것을 특징으로 하는 조성물.
  2. 제1항에 있어서, Nbc, TiN, TiC, Al2O3, SiC, Cr3C2, VC, MO2C, WC 또는 이들의 조합으로 이루어진 경질상 재료를 포함하는 것을 특징으로 하는 조성물.
  3. 제1항 또는 2항에 있어서, Ni, Mo, Mn, Cr, Cu, Si, V, Ti, P, Fe3P, C 또는 이들의 조합으로 이루어진 합금 첨가제를 포함하는 것을 특징으로 하는 조성물.
  4. 제1항 내지 제3항 중 어느 한 항에 있어서, 60㎛이하, 바람직하게는 50㎛ 이하의 평균 입자크기를 갖는 것을 특징으로 하는 조성물.
  5. 제1항 내지 제3항 중 어느 한 항에 있어서, 덩어리 형태를 취하고 있는 것을 특징으로 하는 조성물.
  6. 해면철과 경질상 재료를 포함하고 있으며 연마과정 동안에 혼합된 분말로 이루어진 조성물을 제조하기 위한 방법에 있어서, 액체를 함유하고 있는 밀링장치내에서 불활성 분위기하에서 해면철 분말, 경질상 재료의 분말 및 합금 첨가제를 혼합하는 단계와, 원하는 입자크기 및 입자크기 분포가 얻어질 때까지 상기 혼합물을 연마하는 단계와, 그리고 가루가 된 재료를 분리 및 건조시키는 단계를 포함하는 것을 특징으로 하는 방법.
  7. 제6항에 있어서, 상기 액체가 헵탄, 알코올, 시클로헥산, 물 또는 이들의 조합으로 이루어져 있는 것을 특징으로 하는 방법.
  8. 제6항 또는 7항에 있어서, 상기 연마단계가 볼밀내에서 질소 분위기하에서 수행되는 것을 특징으로 하는 방법.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
