铁基软磁粉末复合材料

Iron-Based Soft Magnetic Powder Composites

软磁粉末复合材料的性能主要取决于原材料的纯度、添加元素和适当的生产工艺。采用低夹杂含量的铁粉,在烧结过程中防止氮和碳在大气中溶解,可以大规模生产具有良好软磁性能的粉末冶金零件。本文简要论述软磁粉末复合材料的制造工艺、磁性和主要用途。

Properties of tie soft magnetic powder composites are directly dependent on the purity of raw materials, addition agents and proper production technologies. By using low-impurity iron powder and protecting C and N dissolved at atmosphere during sintering processes, PM parts with better soft magnetic properties can be producted be producted on a large scale, The present paper describes briefly the production technologies, magnetic properties and principal applications of the soft magnetic powder composites.
