Abstract Friction surfacing (FS) is one of the ideal solid-state cladding processes. Intermetallic particles were redistributed randomly after FS, and the microstructure of the coating was highly refined due to the continuous dynamic recrystallization, which also resulted in the evolution of the textures, as examined by scanning electron microscope and electron backscatter diffraction. The corrosion resistance of the coating was improved, which was tested by potentiodynamic polarization, electrochemical impedance spectroscopy and accelerated immersion. Different intermetallic distributions led to the different electrochemical processes in corrosion. The highly refined microstructure contributed to a strengthened passive film.
