6061 Aluminium Alloy

The influence of AlFeSi and Mg2Si phases on corrosion behaviour of the cast 6061 aluminium alloy was investigated. Scanning Kelvin probe force microscopy (SKPFM), electron probe microanalysis (EPMA), and in situ observations by confocal laser scanning microscopy (CLSM) were used. It was found that Mg2Si phases were anodic relative to the matrix and dissolved preferentially without significantly affecting corrosion propagation. The AlFeSi phases’ influence on 6061 aluminium alloy local corrosion was greater than that of the Mg2Si phases. The corroded region width reached five times that of the AlFeSi phase, and the accelerating effect was terminated as the AlFeSi dissolved.

6061 Aluminium Alloy

In this work, the green chemistry conversion coating on 6063 aluminium alloy surface was made and studied by means of (NH4)2Ce(NO3)6-H2O2 as inhibitor, HF-FeCl3 as accelerator. The coating was evaluated in 3.5% NaCl at room temperature by using polarization curve and electrochemical impedance spectroscopy (EIS). The results show the corrosion current density and the conversion coating resistance, for the untreated or treated alloy, are 1.566 uA•cm-2 and 6.621kΩ cm2, 0.0545 uA•cm-2 and 208.56 kΩ cm2 respectively. It indicates the (NH4)2Ce(NO3)6-H2O2 treated surface presents better corrosion behaviour in chloride media than the original material surface. The morphologies, composition and valence state of the coating were examined by scanning electron microscopy (SEM), energy dispersive spectrometry (EDS) and X-ray photoelectron spectroscopy (XPS), respectively. The result indicates that the Ce-Mn conversion coating was made on aluminium alloy surface.
