Abstract
Description
撹拌擂潰機を用いて、Fe基軟磁性合金粒100重量部に対して、バインダとしてPVA(株式会社クラレ製ポバールPVA−205;固形分10%)を2.5重量部添加して混合した。得られた混合物を120℃で10時間乾燥した後、篩に通して混合粉の顆粒を得て、その平均粒径(d50)を60〜80μmの範囲内とした。また、顆粒100重量部に対して、ステアリン酸亜鉛を0.4重量部添加し、容器回転揺動型粉体混合機により混合して、加圧成形に供する混合粉の顆粒を得た。
得られた顆粒を成形金型内に給粉し、油圧プレス機を使用して室温で加圧成形した。成形圧力は0.74GPaとした。得られた成形体は、内径φ7.8mm、外径φ13.5mm、厚み4.3mmのトロイダル形の環状体とした。
得られた成形体を電気炉により大気中で焼鈍し、代表寸法を内径φ7.7mm、外径φ13.4mm、厚み4.3mmとする磁心を得た。熱処理では、室温から焼鈍温度である750℃まで2℃/分で昇温し、その焼鈍温度で1時間保持した後、炉冷した。また、造粒時に添加したバインダなどの有機物が分解されるように、450℃で1時間保持する脱脂工程を熱処理の途中に含めた。
(A)成形体密度dg、焼鈍後密度ds
環状体の成形体と磁心に対し、それらの寸法と質量から体積重量法により密度(kg/m3)を算出し、それぞれを成形体密度dg、焼鈍後密度dsとした。
算出した焼鈍後密度dsを軟磁性合金の真密度で除して磁心の占積率(相対密度)[%]を算出した。なお、上記の真密度は、あらかじめ鋳造して得られた軟磁性合金のインゴットに対する体積重量法により求めた。
環状体の磁心を被測定物として、一次側巻線と二次側巻線とをそれぞれ15ターン巻回し、岩通計測株式会社製B−HアナライザーSY−8232を用いて、最大磁束密度30mT、周波数50kHz〜1000kHzの条件で、室温における磁心損失Pcv(kW/m3)を測定した。
環状体の磁心を被測定物として、導線を30ターン巻回し、LCRメータ(アジレント・テクノロジー株式会社製4284A)を用いて、周波数100kHzで室温にてインダクタンスLを測定し、次式により初透磁率μiを求めた。
初透磁率μi=(le×L)/(μ0×Ae×N2)
[le:磁路長(mm)、L:試料のインダクタンス(H)、μ0:真空の透磁率=4π×10−7(H/m)、Ae:磁心の断面積(mm2)、N:コイルの巻数]
環状体の磁心を被測定物として、導線を30ターン巻回し、10kA/mの直流磁界を印加した状態にて、LCRメータ(アジレント・テクノロジー株式会社社製4284A)を用いて、周波数100kHzで室温にてインダクタンスLを測定し、前述した初透磁率μiと同様にして増分透磁率μΔを求めた。
JIS Z2507に基づき、引張・圧縮試験機(株式会社島津製作所製オートグラフAG−1)の定盤間に被測定物である環状体の磁心を配置し、その磁心に径方向から荷重を与えて破壊時の最大加重P(N)を測定し、次式から圧環強度σr(MPa)を求めた。
圧環強度σr(MPa)=P(D−d)/(Id2)
[D:磁心の外径(mm)、d:磁心の厚み〔内外径差の1/2〕(mm)、I:磁心の高さ(mm)]
被測定物である磁心の対向する二平面に導電性接着剤を塗り、その接着剤が乾燥し固化してから電極の間に磁心をセットし、電気抵抗測定装置(株式会社エーディーシー製8340A)により50Vの直流電圧を印加して抵抗値R(Ω)を測定し、次式により比抵抗ρ(Ω・m)を算出した。
比抵抗ρ(Ω・m)=R×(A/t)
[A:磁心の平面の面積〔電極面積〕(m2)、t:磁心の厚み〔電極間距離〕(m)]
