3、Ni3Si2相中出現(xiàn)了擇優(yōu)取向。此外，涂層內(nèi)的磁疇變得更為活躍，更容易隨著外部磁場的細微變化而有序排列。涂層截面顯微硬度顯著提高，表面殘余應(yīng)力波動明顯，涂層的磨損量降低了近13.6%。實驗結(jié)果表明，穩(wěn)恒磁場可以有效地改善涂層質(zhì)量。此外，探討了穩(wěn)定磁場下噴涂提高Ni基涂層性能的機理。;The NiCrBSi coating was sprayed onto the 45 steel under a steady magnetic field. The microstructure, mechanical properties, and friction and wear properties of coatings were studied. In the steady magnetic field, the coating porosity decreases dramatically. No new phase forms, but the preferred orientation occurs for the γ-Ni, FeNi3, and Ni3Si2 phases. Moreover, the magnetic domains within the coating become more active and more ordered with subtle variations in external magnetic fields. The microhardness of the cross section of coating increases significantly, the residual stress on the surface fluctuates obviously, and the wear amount of the coating decreases by nearly 13.6%. Results show that a steady magnetic field can improve the coating quality effectively. Besides, the mechanism of property enhancement of Ni-based coating by spraying under steady magnetic field was discussed."/>
