Title:
非晶質金属形状を切断するための選択的エッチングプロセスおよびそれから作られた構成要素
Document Type and Number:
Japanese Patent JP5372326
Kind Code:
B2
Abstract:
A plurality of layers of the shapes is assembled by adhesive lamination to form a generally polyhedrally shaped bulk amorphous metal magnetic component useful in high efficiency inductive devices. The bulk amorphous metal magnetic component may include an arcuate surface, and preferably includes two arcuate surfaces that are disposed opposite to each other. When the component is operated at an excitation frequency "f" to a peak induction level B max , the component exhibits a core-loss less than about "L" wherein L is given by the formula L - 0.005 f (B max ) 1.5 + 0.000012 f 1.5 (B max ) 1.6 , said core loss, said excitation frequency and said peak induction level being measured in watts per kilogram, hertz, and teslas, respectively. Performance characteristics of the bulk amorphous metal magnetic component of the present invention are significantly better than those of silicon-steel components operated over the same frequency range.
