Özet

The purpose of this study was to investigate the effect adding Pb at different ratios had on the corrosion properties of Mg alloys. Pb, at a rate of 0.2%, 0.5%, and 1%, was added to Mg-10% Al-12Si. The microstructure characterisation, mechanical and corrosion properties of alloys, produced using a casting method was investigated. Light Optical Microscopy (LOM), X-Ray Diffraction (XRD) analyses and a Scanning Electron Microscope (SEM) were used to conduct the microstructure characterisation of investigated alloys. Corrosion tests were performed by suspending the samples of certain sizes into the 3.5% NaCl solutions measuring the weight loss, and also by potentiodynamic polarisation measurements in the same solution. According to corrosion experiment results, I-kor decreased with the addition of Pb, causing an increase in the corrosion resistance. (C) 2012 Elsevier Ltd. All rights reserved.
