摘要：
This investigation was focused on the laser cladding of FeCrNi coating. In our study, the characteristics of the FeCrNi coating have been studied, the morphology and microstructure of the cladding layers were analyzed by optical microscopy (OM) and scanning electron microscopy (SEM), the chemical composition was measured by energy dispersive spectrometer (EDS), the hardness were measured by microhardness tester. The thermal field in the laser cladding of FeCrNi coating has been calculated, the cooling rate of moving solid-liquid interface has been studied. At last, the hardness distribution of each cladding layer has been measured.
