Abstract Ni-based alloy coating was prepared on the Q235 carbon steel substrate via laser cladding with a high power diode laser. The microstructure, composition and erosion-corrosion behavior of the coating were characterized by means of SEM+EDS and a home-made pipe flow erosion-corrosion tester. The effect of erosion angle and solid particles on the erosion-corrosion behavior of the coating were investigated. Results show that the laser-clad Ni-based alloy coating had uniform microstructure and fewer defects. The erosion-corrosion behavior of the coating was greatly affected by the synergistic effect of the normal stress and shear stress in flow. In addition, the addition of solid particles further reduced the corrosion resistance of the coating.
