Description
Cr:30質量%、Mo:5質量%、N:0.3質量%を含むCo基合金組成物に、炭素をそれぞれ0.5質量%、1質量%、2質量%、3質量%、4質量%、5質量%添加した原料を真空溶解し、アルゴンガス中でガスアトマイズして、合金粉末を作成した。これらの粉末の平均粒径は、アトマイズ条件と、メッシュ篩とを調整することで、1μmから200μmとした。粉末の粒度分布の測定結果を、図1に示す。また、真空溶解した時に、溶湯の一部を金型に鋳込み、インゴットも作成した。
Claims (3)
- Cr:30質量%と、Mo:5質量%と、炭素:1.0〜5.0質量%と、N:0〜0.6質量%とを含み、残部がCoおよび不可避不純物から成ることを特徴とするCo基合金粉末。
- 粒子径が、1μm以上、200μm以下の粉末から成ることを特徴とする、請求項1記載のCo基合金粉末。
- 電子ビーム積層造形に用いられることを特徴とする請求項1または2記載のCo基合金粉末。
