The preparation of iron-nitrogen compounds was studied by laser nitriding method (LN method). On the basis of this, the surface of the oriented silicon steel was laser-nitrided. The samples were analyzed by XPS photoelectron spectroscopy. The results show that under a certain process parameters (laser power, scanning speed, etc.) can be iron-nitrogen compounds to form iron-nitrogen compounds. Select the appropriate scanning speed, scanning spacing and N2 beam orientation of silicon steel surface after laser nitriding, the orientation of silicon steel surface generated iron nitrogen compounds. Using the magnetic domain observation device observed that the laser nitriding, the orientation of the silicon steel significantly refined domain, which can reduce the iron loss of oriented silicon steel.
