The Corrosion Resistance Discrimination of TC11 Titanium Alloy Using Scanning Kelvin Probe

Abstract:

Article Preview

Surface potential of TC11 titanium alloy handled by beta phase (1150°C) solid solution for one hour and then taking water cooling, air cooling and furnace cooling as cold method were investigated using scanning Kelvin probe technique. The corrosion resistance difference of samples was analyzed through their surface potential. At the same time, corrosion experiments were adopted to verify it. The results show that the result of the samples corrosion resistance analyzed by scanning Kelvin probe technique is reliable and the method is feasible. Compared with water cooling sample, the corrosion resistance of furnace cooling and air cooling samples is worse and their surface potential present cathode and anode area obviously. The corrosion of furnace cooling sample is slight serious to that of air cooling sample in the early corrosion, but their corrosion resistances are almost equal. Passivation layer formed by alloy elements in the water cooling sample avails to prevent alloy from corrosion.
