Description

合金粉末及磁性部件
技术领域
本发明涉及可使用于传感器及噪音滤波器、扼流线圈等电子部件的Fe基非晶合金粉末。
背景技术
专利文献1提出一种具有非晶相作为主相的合金粉末。专利文献1的合金粉末的平均粒径为0.7μm以上且5.0μm以下。

发明内容
【发明想要解决的问题】
若考虑对于在如噪音滤波器及扼流线圈这样的电子部件中的使用，相较于马达用途，饱和磁通密度可以较小也可，另一方面，需要矫顽力小、抑制铁损耗至较低。为了满足此要求，且稳定的得到粒径大的粉末，要求提高合金的非晶形成能力。若由非晶形成能力高的合金制造粉末，则可提高特性良好的粉末形成的成品率。
因此，本发明的目的在于提供一种具有高非晶形成能力的合金粉末。
【解决问题的方式】
本发明的一个方案是提供非晶相作为主相或具有非晶相与α-Fe的结晶相的混相组织的组成式Fe100-a-b-c-d-e-fCoaBbSicPdCueCf的合金粉末。参数满足以下条件：3.5≤a≤4.5at％、6≤b≤15at％、2≤c≤11at％、3≤d≤5at％、0.5≤e≤1.1at％、0≤f≤2at％。另外，合金粉末的粒径为90μm以下。
另外，本发明的另一方案提供使用上述合金粉末构成的磁性部件。
发明的效果
含有3.5at％以上且4.5at％以下的Co的FeCoBSiPCu合金或FeCoBSiPCuC合金，具有高非晶形成能力，可容易地得到大粒径的合金粉末。另外，由于降低了Fe的比例，不适于纳米结晶化，另一方面还具有在作为矫顽力小、铁损耗也低的电子部件用的优异磁性特性。即使是粒径大的粉末也变得具有良好的磁性特性，故成品率提高。
具体实施方式
关于本发明可以多样的变形及各种方案实现，作为其中一例，以特定实施方案，详细说明如下。实施方案不限于本发明在此所揭示的特定方案，其对象包含附加的权利要求书所记载的范围内的全部变形例、均等物、替代例。
本发明的实施方案的合金粉末，适合作为如噪音滤波器的电子部件用，组成式为Fe100-a-b-c-d-e-fCoaBbSicPdCueCf。在此，3.5≤a≤4.5at％、6≤b≤15at％、2＜c≤11at％、3≤d≤5at％、0.5≤e≤1.1at％、0≤f≤2at％。即，不含C时，组成式为Fe100-a-b-c-d- eCoaBbSicPdCue，含有0＜f≤2at％的C时，组成式为Fe100-a-b-c-d-e-fCoaBbSicPdCueCf。
在本实施形态中，Co元素为负责非晶相形成的必须元素。若对于FeBSiPCu合金或FeBSiPCuC合金添加一定量的Co元素，则FeBSiPCu合金或FeBSiPCuC合金的非晶相形成能力提高，故可稳定地制作粒径大的合金粉末。但是，若Co的比例少于3.5at％，则液体急速冷冻条件下的非晶相的形成能力降低，其结果，化合物相析出到合金粉末中而饱和磁通密度降低。而若Co的比例多于4.5at％，则导致矫顽力上升。因此，Co的比例较佳为3.5at％以上、4.5at％以下。非晶相形成能力提高，故即使在Co的比例多到3.5at％以上的情况，藉由将其他元素B、Si、P、Cu的値调整如下述，可得到良好的磁性特性。
在本实施形态中，B元素为负责非晶相形成的必须元素。若B的比例少于6at％，则液体急速冷冻条件下的非晶相形成能力降低，其结果，化合物相析出到合金粉末中而饱和磁通密度降低，同时矫顽力上升。若B的比例多于15at％，则饱和磁通密度降低。因此，B的比例理想的为6at％以上且15at％以下。
在本实施形态中，Si元素为负责非晶形成的必须元素。若Si的比例少于2at％，则液体急速冷冻条件下的非晶相形成能力降低，其结果，化合物相析出到合金粉末中而饱和磁通密度降低，同时矫顽力提高。若Si的比例多于11at％，则导致矫顽力上升。因此，Si的比例理想的为2at％以上且11at％以下。
在本实施形态中，P元素为负责非晶形成的必须元素。若P的比例少于3at％，则液体急速冷冻条件下的非晶相的形成能力降低，其结果，化合物相析出到合金粉末中而矫顽力上升。若P的比例多于5at％，饱和磁通密度降低。因此，P的比例理想的为3at％以上且5at％以下。
在本实施形态中，Cu元素为负责非晶形成的必须元素。若Cu的比例少于0.5at％，则饱和磁通密度降低。若Cu的比例多于1.1at％，则液体急速冷冻条件下的非晶相形成能力降低，其结果，化合物相析出到合金粉末中而饱和磁通密度降低，同时矫顽力上升。因此，Cu的比例理想的为0.5at％以上且1.1at％以下。
在本实施形态中，Fe元素为主元素，占上述组成式的剩余部分且为负责磁性的必须元素。为了提高饱和磁通密度及降低原料价格，基本上优选Fe的比例多。然而，Fe的比例若超过83.5at％，化合物相多量析出，饱和磁通密度极端降低的情况变多。另外，若Fe的比例超过79at％，由于非晶形成能力降低而有矫顽力增加的倾向，所以为了避免此情况有必要将半金属元素的比例严密地调整。因此，Fe的比例理想为83.5at％以下，另外，优选为79at％以下。
也可对具有上述组成式Fe100-a-b-c-d-eCoaBbSicPdCue的合金组成物添加一定量的C元素以降低合金组成物总材料成本。单，若C的比例超过2at％，则饱和磁通密度降低。因此，即使添加C元素使合金组成物的组成式为Fe100-a-b-c-d-e-fCoaBbSicPdCueCf的情况，C的比例较理想为2at％以下(不含0)。
本实施形态的合金粉末，可藉由水雾化法或气体雾化法制作，也可藉由将薄带的合金组成物粉碎而制作。
进一步，将制成的合金粉末过筛，分为粉末粒径为90μm以下的粉末与超过90μm的粉末。如此而得的本实施方式的合金粉末，具有90μm以下的粒径且具有1.6T以上的高饱和磁通密度与100A/m以下的低矫顽力。
将本实施方式的合金粉末成形，可形成卷磁芯、层叠磁芯、压粉磁芯等磁芯。另外，使用该磁芯，可提供如传感器及噪音滤波器、扼流线圈这样的电子部件。
【实施例】
以下，关于本发明的实施方式，参考多个实施例及多个比较例更详细说明。
(实施例1～11及比较例1～10)
首先，验证不含C的FeCoBSiPCu合金。详细而言，称量原料使其为如下述表1所示的本发明的实施例1～11及比较例1～10的合金组成，藉由高频感应熔炼处理熔炼而制作母合金。将此母合金以气体雾化法处理，得到粉末。金属熔液(molten metal)的吐出量为平均15g/秒以下，气体压力定为10MPa以上。将如此而得的粉末过筛，分为粉末粒径为90μm以下的粉末与超过90μm的粉末，得到实施例1～11及比较例1～10的合金粉末。合金粉末的各种饱和磁通密度Bs使用振动样品型磁力计(VMS)以800kA/m的磁场测定。各合金粉末的矫顽力Hc使用直流BH指示器以23.9kA/m(300奥斯特)的磁场测定。测定结果如表4所示。
