Application of bilayer silanisation treatment to improve corrosion resistance and bond durability of aluminium alloy

A universal laser marking approach for treating aluminum alloy surfaces with enhanced anticorrosion, hardness and reduced friction

“…15 However, these improvements are still limited owing to the low solid solubility (<1 at.%) between the doped metals and Al. 29 Although various surface modications have been successfully carried out, there still are some challenges, including the current methodology requiring rigorous and time consuming fabrication processes. [16][17][18][19][20][21] Through depositing a coating on their surface, their corrosion and wear resistance could be enhanced.…”

“…28 By forming compact Al-O-Si and Si-O-Si covalent bond network bridges with sulphide phases in the interface zone, Guo et al have produced a bilayer silanisation lm layer on AA2024-T3 alloy and remarkably improved the corrosion resistance of the alloy. 29 Although various surface modications have been successfully carried out, there still are some challenges, including the current methodology requiring rigorous and time consuming fabrication processes. More importantly, the processes cannot be performed on the large scale and most of the fabricated surface lms, which are reported to date, are easily destroyed.…”
