中科院宁波材料所非晶软磁团队一直致力于非晶合金新材料的开发与应用研究。近日,研究团队在铁基非晶成分设计及其涂层性能研究方面取得进展。通过利用Ni和P取代SAM合金中昂贵的稀土、W和Mo,以及调控Cr和Mo的比例,获得一系列非晶形成能力大于2 mm的新型铁基块体非晶合金。利用自主搭建的气雾化设备制备了高质量的球形非晶粉末,成粉率(>100目)达80% Chinese Academy of Sciences, Ningbo Materials amorphous soft magnetic team has been committed to the development of amorphous alloy materials and application research. Recently, the research team made progress in the research of iron-based amorphous composition design and coating properties. By using Ni and P instead of the expensive rare earths, W and Mo, and controlling the ratio of Cr to Mo in SAM alloy, a series of new Fe-based bulk amorphous alloys with amorphous formability greater than 2 mm were obtained. High-quality spherical amorphous powder was prepared by the self-built gas atomization equipment, the yield of powder (> 100 mesh) reached 80%
