Corrosion behavior of antimony (SB) modified galfan (ZN-AL) coated steel
High corrosion resistance of Zn-Al-Mg (ZAM) alloy is widely used in steel wire rope protection. This alloy, however, due to Mg reactivity, easily induced dross formation containing MgZn2 and Mg2Zn11 which reduced the coating integrity. Thus, in this work, Mg is replaced with various wt.% Sb (ZAS) co...

| Summary: | High corrosion resistance of Zn-Al-Mg (ZAM) alloy is widely used in steel wire rope protection. This alloy, however, due to Mg reactivity, easily induced dross formation containing MgZn2 and Mg2Zn11 which reduced the coating integrity. Thus, in this work, Mg is replaced with various wt.% Sb (ZAS) coated on steel surface will via hot-dip process at the eutectic environment. The thickness of the intermetallic layer and coating thickness were observed using an optical microscope and SEM. It was found that 0.3 wt.% Sb improved the corrosion performance 45.5% (0.00267 mmpy) than ZAM coated steel (0.00490 mmpy) under accelerated corrosive medium of 3.5% NaCl. |
