Abstract

In this paper, the effect of die bearing parameters (die bearing length and die reduction ratio) on corrosion response of extruded Al-Zn-Mg alloy was investigated. The alloy was target material for production of automobile bumper beams. Medium carbon steel dies with entry angles of 750, 900, 1050, 1200, 1500 and reduction ratios of 0.21, 0.40, 0.48 and 0.62 were used to extrude the alloy at temperature of 5000C. The extruded samples were subjected to electrochemical corrosion using Tafel polarization technique. The potential dynamic polarization curves indicated improvement in the corrosion resistance of the extruded alloy, and the corrosion rate under extruded condition increased with increase in both die angle and reduction ratio. It was concluded that the Al-Zn-Mg alloy is suitable for the target application.
