摘要

从机械加工引起矫顽力下降的角度研究了Nd-(FeCoNiTi)-B和Nd-Fe-B型薄板烧结磁体的磁性能。发现Nd-(FeCoNiTi)-B型磁体的变质层的厚度小于Nd-Fe-B型磁体的劣化层的厚度。用Nd-(FeCoNiTi)-B磁体的韧性和细粒结构来解释这种现象。建议Nd-(FeCoNiTi)-B磁体可以以50μm厚的片的形式使用。

Magnetic Properties of Thin Sheets (50 μm) of Nd-(FeCoNiTi)-B Sintered Magnets
The magnetic properties of Nd-(FeCoNiTi)-B and Nd-Fe-B type sintered magnets in thin sheet form were investigated from the standpoint of the deterioration in coercivity caused by machining. It was found that the thickness of a deteriorated layer of an Nd-(FeCoNiTi)-B type magnet is smaller than that of an Nd-Fe-B type magnet. This phenomenon is explained in terms of the toughness and fine-grained structure of Nd-(FeCoNiTi)-B magnets. It is suggested that Nd-(FeCoNiTi)-B magnets may be used in the form of 50 μm thick sheets.
