Achieving In-Situ Fe-based Spherical Particles for Magnetic Abrasive Finishing Process of Zirconium Tube Via Gas Nitriding Method
MATERIALS LETTERS(2024)
摘要
The magnetic abrasive powders have great influence on the magnetic abrasive finishing accuracy and efficiency. A new kind of Fe-based spherical magnetic abrasive particles with Fe2N precipitates and Fe4N matrix was successfully synthesized by gas nitriding. The results show that the prepared Fe-based magnetic abrasive particles can reduce the roughness of the Zirconium tube from 0.325 to 0.154 mu m by four MAF passes. The high hardness and wear resistance of the Fe-based magnetic abrasive particles are assessed based on the Vickers hardness and nanoindentation results. This study can provide theoretical and experimental support for fabricating highperformance magnetic abrasive particles.
