Abstract:Both salt spray tests and acid rain tests were employed to investigate the corrosion resistance performance of the hot-dip coatings of Al-Zn-Si-Re and Al-Zn-Si. And the effects of the Al-Zn-Si-Re hot-dip coating production process on the mechanical properties of steel were studied by tensile tests. The results show that two kinds of coatings used in steel of transmission tower structure have superior corrosion resistance performances and that the performance of Al-Zn-Si-Re coating is better. The hot dipping process technique has no negative impact on the mechanical behaviors of the steel and Al-Zn-Si-Re hot-dip coating corrosion resistance technique can be widely used in the transmission tower structures.

Keywords:transmission tower structure; Al-Zn-Si hot-dip coating; Al-Zn-Si-Re hot-dip coating; corrosion resistance performance; mechanical behavior
