In this paper, to improve wear resistance of components such as screws under severe friction-wear, Fe-Cr-C-Mo-V-Ti-N hardfacing coatings were further developed. The hardfacing coatings were acquired by shielded manual arc welding (SMAW) method. The ferroalloys added into the coating flux of the hardfaced electrode were jointly nitrided. The microstructure of the coatings was carried out using X-ray diffraction(XRD), optical microscope(OM), field emission scanning electron microscope (FESEM) and energy dispersive Xray spectrometry (EDS). In addition, FactSage 7.0 software was employed to calculate the equilibrium phase diagram of the hardfacings. The wear resistance was performed on a pin-on-disc machine. The Fe-Cr-C- Mo-V-Ti-N hardfacings exhibited higher wear resistance than cladding layer without nitrides.
