of Mechanics, Chinese Academy of Sciences, Beijing 100080, China) Abstract: Amorphous [Al-Si-O] coatings were deposited on aluminum alloy by plasma electrolytic oxidation(PEO). The process parameters... deposited on aluminum alloy. If sodium silicate(below 20g/L) is added in the electrolyte, the growth rate of the coatings is increased and the coatings consist of Al2O3 and Al-Si-O phase with complex......
of the structural aircraft parts. 2 EXPERIMENTAL The Al alloy assessed in this investigation was AA 7010-T7651 with a chemical composition of Zn 6.30, Mg 2.34, Cu 1.75, Zr 0.12, Fe 0.05, Si 0.04, Ti... changes of Zn, Cu, Mg, Fe and Si between the surface and this depth are 0.3%, 0.15%, 0.13%, 0.01% and -0.01%, respectively. The remaining elements Ti, Zr and Mn do not change much through the thickness......
