The work aims to prepare high-performance Fe-based cladding coating reinforced by AlN-Fe3Al by the plasma cladding method. Iron-based alloy powder and aluminum powder were used as reactive sources to prepare Fe-based cladding coatings on Q235 steel substrate by plasma cladding method with nitrogen as reactant and protective gas. The effects of Al on the phase composition, microstructure, microhardness, wear resistance and corrosion resistance of the Fe-based cladding coatings were investigated by XRD, SEM, microhardness tester, wear resistance and electrochemistry workstation. The cladding coating prepared by Fe-based alloy powder was composed of α-Fe and Cr, while AlN, Fe3Al and Cr5Al8 were detected in the cladding coating with Al (mass fraction of 6%). Both cladding coatings were well formed and metallurgically bonded with the substrate. The in situsynthesized AlN particles distributing in the cladding coating with Al were smaller than 5 μm. The largest microhardness of the cladding coating increased from 340 HV0.5 to 1350 HV0.5 due to the addition of Al. Compared to the cladding coating without Al, the wear resistance of the coating with Al increased by 4.6-fold. Al could from al layer of passive film on the cladding coating and improved the corrosion resistance significantly. The wear and corrosion resistance of AlN-Fe3Al reinforced Fe-based cladding coating prepared by plasma cladding technology are improved obviously.
