Abstract
The porous Fe-Ni powders were successfully prepared by the gas nitriding, electroless plating and then removal of denitrogen & phosphorus under high temperature. The phases of the powders were determined by X-ray diffraction (XRD) utilizing Cu Ka radiation. Scanning electron microscope (SEM) was used to characterize the morphology of the porous powders. The magnetic properties of the powders were measured by a vibration sample magnetometer (VSM). The result shows that the porous Fe-Ni-N powder was mainly composed of γ’-Fe4 N and FeNi3 while the porous Fe-Ni powders were comprised by Fe0.64Ni0.36 and Ni. The porous Fe-Ni powder has a good soft magnetic property with Saturation Magnetization of 113.5emu/g and coercivity of 162.9Oe.
