Intermetallic Particles-Induced Pitting Corrosion in 6061-T651 Aluminium Alloy
View through CrossRef
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 X-ray Spectroscopy revealed the presence of Al-Si-Fe-containing particles that acted as cathodic sites and promoted the matrix dissolution. The effect of pH and chloride solution is assessed.
