概要（目的・用途・実施内容）/ Abstract (Aim, Use Applications and Contents)
To investigated the chemical composition of the galvanized steel surface after hot water treatment, XPS test was performed.
実験 / Experimental
A XPS instrument (PHI 5000 VersaProbe, ULVAC-PHI, Inc.) was used. A high vacuum condition (< 1× 10-6 Pa) was ensured and a standard monochromatic Al Kα X-ray source (1486.6 eV) with focus point of 100 μm was utilized. Survey spectra were obtained with a pass energy of 117.4 eV and an energy step of 1.0 eV. High-resolution spectra were obtained with a pass energy of 23.5 eV and an energy step of 0.1 eV. All the spectra were calibrated by shifting C1s peak to 284.8 eV to avoid the charging effect.
結果と考察 / Results and Discussion
The result showed that two kinds of chemical compositions existed on the hot water treated galvanized steel surface: pure zinc and zinc oxide. The generated new chemical composition was zinc oxide, resulting from the chemical reaction between water and Zn. The stability of zinc oxide is better than pure zinc, providing better corrosion resistance to the galvanized steel.
