Description
技术领域
本发明涉及软磁铁基纳米晶合金及其制备技术领域，具体涉及一种抗直流的铁基纳米晶合金及其制备方法。
背景技术
铁基软磁纳米晶合金由于具有高饱和磁感应强度、高磁导率、低损耗、低矫顽力等优异的软磁性能，且具有原料价格低廉和生产工艺简单等优点，在电网、航空航天、互感器、吸波、海洋涂层、电磁屏蔽和催化与降解等方面也有不小的应用潜力。
随着科学技术的迅速发展，电子设备趋向于小型化、环保化，希望铁基纳米晶合金具有上述优异的磁性能外，在制备低噪声放大器、电流互感器和开关电源等电力电子器件时，还要求在外加直流偏置电流的工作状态下具有高的稳定性与可靠性，即良好的抗直流能力。
2003年开始，德国VAC开发了一系列具有抗直流能力的纳米晶合金（专利US6563411，CN200480005617.7），拉开了抗直流纳米晶合金的序幕。
对后来抗直流纳米晶相关文献和专利进行调研后，发现大多纳米晶合金都含有贵金属Co和较多的Nb元素，这无疑会增加材料的价格成本并降低其饱和磁感应强度。
发明内容
针对现有技术中存在的上述一个或多个技术问题，本发明的目的是提供一种具有抗直流能力的铁基纳米晶合金和制备方法。
为达到以上目的，本发明是采取如下技术方案予以实现：
一种抗直流的铁基纳米晶合金，其特征在于该合金的分子简式为Fe76-xNixSi13B8Nb2Cu1(0<x≦16)，式中x及其数字均为原子百分含量。其制备包括如下步骤：
以工业纯铁、镍、硅、硼、铌和铜为原料，按照合金组分中的元素及其原子百分含量配制原料，将称量好的原料放在高频感应熔炼炉或电弧炉中，在纯氩气进行熔炼得到母合金；将得到的母合金破碎后，装到开口的石英玻璃管中，置于铸造设备的感应线圈中；空气气氛中，将熔化后的合金液喷到转速为20~50 m/s的铜辊上制备出连续非晶条带。
将条带绕制成铁芯。然后，对上述铁芯在横磁场中进行晶化退火，随炉冷却。测量上述铁基纳米晶条带的饱和磁感应强度Bs，有效磁导率(μ e)，矫顽力（Hc）和各向异性场Hk。
具体实施方式
下面结合实施例，对本发明做进一步地描述，但绝不限制本发明的范围：
实施例1
以工业纯铁、镍、硅、硼、铌和铜为原料，按照Fe69Ni7Si13B8Nb2Cu1合金组分中的元素及其原子百分含量配制原料，将配称量好的原料放在高频感应熔炼炉或电弧炉中，在纯氩气进行熔炼得到母合金；将得到的母合金破碎后，装到开口的石英玻璃管中，置于铸造设备的感应线圈中；空气气氛中，将熔化后的合金液喷到转速为40 m/s的铜辊上制备出连续非晶条带。将条带绕制成宽度为10 mm，内直径为14 mm，外径为20 mm的铁芯。然后，对上述铁芯在1500 Gs的磁场中500 ℃晶化退火30 min，随炉冷却。
实施例2
以工业纯铁、镍、硅、硼、铌和铜为原料，按照Fe66Ni10Si13B8Nb2Cu1合金组分中的元素及其原子百分含量配制原料，将配称量好的原料放在高频感应熔炼炉或电弧炉中，在纯氩气进行熔炼得到母合金；将得到的母合金破碎后，装到开口的石英玻璃管中，置于铸造设备的感应线圈中；空气气氛中，将熔化后的合金液喷到转速为40 m/s的铜辊上制备出连续非晶条带。将条带绕制成宽度为10 mm，内直径为14 mm，外径为20 mm的铁芯。然后，对上述铁芯在1500 Gs的磁场中500 ℃晶化退火30 min，随炉冷却。
实施例3
以工业纯铁、镍、硅、硼、铌和铜为原料，按照Fe64Ni12Si13B8Nb2Cu1合金组分中的元素及其原子百分含量配制原料，将配称量好的原料放在高频感应熔炼炉或电弧炉中，在纯氩气进行熔炼得到母合金；将得到的母合金破碎后，装到开口的石英玻璃管中，置于铸造设备的感应线圈中；空气气氛中，将熔化后的合金液喷到转速为40 m/s的铜辊上制备出连续非晶条带。将条带绕制成宽度为10 mm，内直径为14 mm，外径为20 mm的铁芯。然后，对上述铁芯在1500 Gs的磁场中500 ℃晶化退火30 min，随炉冷却。
测量上述铁基纳米晶条带的饱和磁感应强度Bs；矫顽力（Hc）以及各向异性场Hk，得到如下结果（表1）。可以发现，本申请开发的铁基纳米晶合金具有1.2 T左右的高饱和磁感应强度，低矫顽力3.0~5.0 A/m，以及可以达到220 A/m左右的各向异性场Hk，表明该系列合金具有良好的抗直流性能以及其它软磁性能，且未使用Co，Nb含量极少，生产成本较低。
