摘要

本研究描述了一种3D熔融沉积建模(FDM)打印工艺，使用石墨烯浸渍的聚乳酸(G-PLA)长丝来创建一种新型的刚性、塑性、不导电和防腐层。因此，本文演示了使用FDM方法3D打印塑料层的可能性。像N35 NdFeB这样的商业磁铁可以通过增材制造来生产有效的屏蔽膜。随着涂层厚度的增加，G-PLA涂层的残余量从1.17 T降低到1.01 T。在暴露于所有NaCl水溶液(0.5和1m)后进行目测，没有发现涂层腐蚀的证据。

Effect of Graphene-Based Coating 3D Printing Process on the Remanence and Corrosion of Sintered NdFeB Magnets

This study describes a 3D fused deposition modeling (FDM) printing process using a graphene-impregnated polylactic acid (G-PLA) filament to create a new type of rigid, plastic, nonconductive, and anticorrosion layer. Therefore, the possibility of 3D printing a plastic layer using FDM methods is demonstrated herein. A commercial magnet such as N35 NdFeB can be used to produce an efficient shielding film by additive manufacturing. As the coating layer thickness increases, the remanence decreases from 1.17 to 1.01 T for the G-PLA coating. Visual tests were performed after exposure to all aqueous NaCl test solutions (0.5 and 1 M), and no evidence of corrosion of the coating was obtained.
