Protection of aluminum alloys AMg6 and D16 from atmospheric corrosion with aqueous solutions of inhibitors
Abstract
The article discusses the possibilities of protecting aluminum alloys AMg6 and D16 with aqueous solutions of corrosion inhibitors such as carboxylates and trialkoxysilanes. The effectiveness of their inhibition of anodic dissolution of the AMg6 alloy in a neutral borate buffer solution (pH 7.4) was studied. The protective ability of the layers was assessed using the drop test method, tests in a thermal moisture chamber and a salt fog chamber. The effectiveness of processing aluminum alloys in aqueous solutions of organic inhibitors is correlated with the protective ability of chromate films. It has been shown that modification of aluminum alloys with a mixture of oleyl sarcosinate and aminoethylaminopropyltrimethoxysilane at a ratio of 3:1 is the most effective method of protection against atmospheric corrosion.
