基于DOE理论的钕铁硼晶界扩散工艺参数的优化
|
摘要
论述了DOE理论对Nd-Fe-B晶界扩散工艺参数的优化过程。通过建立正确的模型,设置主要的影响因子及其对应的水平值,进行了一系列的相关实验。结果表明,与传统的实验方法相比较,采用DOE理论能明显减少实验次数,缩短实验周期,同时也降低了研究成本。通过使用DOE理论指导实验,磁体的矫顽力由1 615.88kA/m提高到2 292.48kA/m,增长了41.9%。
The process of optimizing parameters of grain boundary diffusion process by DOE theory detailed was discussed.A series of experiments are conducted through building correct models,setting main impact factors and its corresponding horizontal values.The results show that compared with the traditional experimental method,the DOE theory can obviously reduce experiment number,shorten experimental period and cut down the cost of research meanwhile.The coercivity of magnet increases from 1 615.88 kA/m to 2 292.48 kA/m,increasing by 41.9% under the guidance of DOE theory.
