dispersive spectroscopy (SEM-WDS). The results show that adding 0.075% (mass fraction) Co into the Zn bath can completely inhibit the silicon reactivity in the galvanized coating on the Q235 steel. But for the Q345 steel, to inhibit the silicon reactivity, 0.3% Co should be added into the Zn bath. The loose ζ layer is transformed into the Co-rich ζ layer contacted directly with the liquid phase......
