Femtosecond laser polishing yttria-stabilized zirconia coatings for improving molten salts corrosion resistance

•Improvement of hot corrosion behavior of YSZ coating by femtosecond laser polishing.•Reduction of roughness from Ra 6.615 μm to Ra 1.562 μm by laser polishing.•Voids healing occur due to volume absorption and multiple reflections of laser.•Removal of pores and polished surface retard leaching of Y...
