Abstract
【解決手段】Nb,Ta,Ti,Zr,Vから成る群から選択された少なくとも1種を0.001〜0.03原子%含む水アトマイズFe粉末が、母相に、Nb,Ta,Ti,ZrあるいはVの少なくとも1種と、酸素とを主成分とする平均粒子径が0.02μm以上0.5μm以下の粒子を析出させた圧粉磁性体用軟磁性粉末である。開示された軟磁性粉末の製造方法は、Nb,Ta,Ti,Zr,Vから成る群から選択された少なくとも1種を添加し、水素を含む還元雰囲気で熱処理することにより製造する圧粉磁性体用軟磁性粉末の製造方法である。この方法により、ガス不純物、特に酸素を低減,無害化して、Fe粉末及び成形体の磁気特性を向上させることができる。
【選択図】 図3
Description
以下、実施例で更に詳細を説明する。
25種類のFe粉末は、水アトマイズFe粉であるため、酸素を不純物として多量(質量%で0.17〜0.2%の範囲)に含んでいる。酸化皮膜形成の寄与が大である。不純物Cの濃度は0.001〜0.003%程度である。またN濃度は、いずれの材料でも0.002%以下となり、非常に少ない。C,Nはアトマイズ中に水(すなわち酸素)との反応でかなりの量が除去されていると思われる。
温度範囲で等時焼鈍実験を実施した。焼鈍条件は、100℃からスタートして、温度上昇間隔ΔT=50℃,保持時間30分である。100,200,300,400,450,500,550,600,650,700,800までそれぞれ焼鈍した。焼鈍された成形体を上記のプロセスに従い、室温で硬さ試験した。
径15mm,厚さ5mmのリング形状とした。鉄リン酸ガラスの耐熱温度が最大550℃であ
るため、成形体を窒素ガス雰囲気で530℃で60分間の熱処理を行った。
のフランジ部7と爪部8を数箇所切り出して、アルキメデス法でそれらの密度を測定した。No.5,No.12,No.15,No.21の爪部の密度はそれぞれ平均7.55,7.54,7.56,7.56であった。外周,平坦部を含むフランジ部は爪部より0.01〜0.03低かった。
