| 摘 要： | The Fe3Si based coating was produced on the Fe-1Si steel surface by a pulsed Nd:YAG (yttrium aluminum garnet) laser. Its phase constitution and microstructure were characterized by using X-ray diffraction (XRD),optical microscope (OM),and field emission scanning electron microscope (FESEM) with associated energy dispersive spectroscopy (EDS) and transmission electron microscopy (TEM). The hyperfine structure of the coating was studied by Mssbauer spectra (MS) and the magnetic property was also measured at ...

| Abstract: | The Fe3Si based coating was produced on the Fe-lSi steel surface by a pulsed Nd:YAG (yttrium aluminum garnet) laser. Its phase constitution and microstructure were characterized by using X-ray diffraction (XRD), optical microscope (OM), and field emission scanning electron microscope (FESEM) with associated energy dispersive spectroscopy (EDS) and transmission electron microscopy (TEM). The hyperfine structure of the coating was studied by Mossbauer spectra (MS) and the magnetic property was also measured at room temperature by a vibrating sample magnetometer (VSM). The obtained coating is pore and crack-free with dense microstructure and high Si content. The metallurgical bonding between the coating and the substrate was realized. The micro-structure of the coating is typical fine dendrites. The major phase was confirmed by XRD and TEM to be the ordering DO3 structured Fe3Si phase. In addition, there were smaller amounts of the Fe5Si3 phase and the T-Fe phase in the coating. Compared with the sub-strate, the laser cladding coating has a lower saturation magnetization and a higher coercive force. The poor magnetic property might be because of rapid solidification microstructure and phase constitution in the coating. |
