In　situ　NbC-reinforced　laser　cladding　Ni45　coatings　have　the　advantages　of　high　bond　strengths,　low　dilution　rates,　small　heat-affected　zones　and　good　wear　resistance　and　have　broad　application　prospects　in　the　field　of　surface　strengthening　and　repair　of　workpieces　such　as　automotive　molds　and　engine　turbines.　Previous　studies　have　mostly　used　pure　niobium　powder　for　in　situ　synthesis　to　prepare　Ni-based　NbC　coatings　with　a　high　production　cost.　In　this　paper,　NbC　was　successfully　synthesized　in　situ　in　Ni45　powder　using　inexpensive　FeNb65　and　Cr3C2.　The　prepared　coating　has　a　uniform　microstructure　and　excellent　wear　resistance,　and　the　reinforced　phases　are　mainly　NbC　and　Cr23C6.　Coating　4#　with　25　wt.%　FeNb65　+　Cr3C2　has　the　highest　microhardness　of　776.3HV0.2,　about　1.45　times　that　of　the　Ni45　coating,　and　its　wear　resistance　is　36.36　min/mg,　about　60.6　times　that　of　the　Cr12MoV　steel　base　material　and　about　23.76　times　that　of　the　Ni45　coating.
