Corrosion fatigue performance in simulated sea water of aluminium 6061-T651 welded using ER4043 filler wire

Author: Mutombo, K ; Du Toit, M Date: Oct 2010 The fatigue life of Al6061-T651 for various applied stress amplitudes in the unwelded and welded conditions was significantly lower in 3.5% NaCl simulated sea water solution, compared to that in air. The damage ratio increased with a decrease ... Read more
Influence of liquid surface segregation on the pitting corrosion behavior of semi-solid metal high pressure die cast alloy F357

Author: Moller, H ; Masuku, EP Date: 2009 Semi-solid metal processing results in liquid segregation at the surface of the components. The pitting behaviour of this surface layer of semi-solid metal processed alloy F357 was compared with the centre (or bulk) of cast plates in 3.5% ... Read more
Intermetallic particles-induced pitting corrosion in 6061-T651 aluminium alloy

Author: Mutombo, K Date: Jul 2011 The polished 6061-T651 aluminium alloy was immersed in 3.5% NaCl solution with about 7 ppm dissolved oxygen. Scanning Electron Microscopy equipped with Energy dispersive Xray Spectroscopy revealed the presence of Al-Si-Fe-containing particles ... Read more
