Study of Process of Hot-Dipped Galfan Coating on Q235 Structural Steel

A different production method including a formulated flux has been devised to hot-dip Q235 Galfan alloy coating on structural steel. The microstructure and composition of the Galfan coatings, applied by the hot dip process, was performed using SEM and EDS technology to evaluate the coating thickness and its relationship with technological parameters. The experimental results showed that the coating of specimen has eutectic crystal shape and its thickness is thinner than Zinc coatings’ scale. Moreover, the Galfan plating does not grow with the extension of time for immersion. The temperature of immersion and the extraction speed will affect the coating thickness too.
