“…Hot-dip galvanising (HDG) is a method for protecting steel from environmental corrosion, by covering a layer of Zn on the surface of steel with physical and sacrificial anode protection [1]. In recent decades, several kinds of Zn-Al alloy coatings have been developed to further improve the performance of the technique [2][3][4][5][6][7][8][9][10][11]. In particular, the Zn-5% Al alloy containing a heterogeneous eutectic layer of Zn and Al enables the improvement of corrosion resistance and ductility of the alloy [3,4].…”

The effects of HF pre-treatment on the cerium-based conversion coating on a Zn-5% Al alloy were investigated using a combination of scanning electron microscopy, energy-dispersive Xray spectroscopy, X-ray photoelectron spectroscopy, and electrochemical impedance spectroscopy. The results revealed that a porous structure appeared in the Al-rich phase of Zn-5% Al alloy after HF pre-treatment, and the cerium conversion coating with pretreatment was preferentially deposited on the surface of Al-rich phase and grew fast. Moreover, the corrosion resistance of the cerium conversion coating was improved by HF pre-treatment.
