研究目的
Investigating the preparation and deposition of Pr-Fe-B permanent magnet powder using pulsed laser for application in miniaturized motors.
研究成果
The PLD method enabled the preparation of isotropic Pr-Fe-B magnet powders with high coercivity on a stainless thin shaft, showing no degradation in magnetic properties over time and potential for application in micro magnetization processes.
研究不足
The study focuses on Pr-Fe-B magnets and their application to miniaturized motors, with potential limitations in scalability and cost-effectiveness for industrial applications.
