Embodiment 1
[0031] 1) Pretreatment of aluminum alloy samples
[0032] The pretreatment of the aluminum alloy samples is carried out according to the provisions of the aviation industry standard HB / Z 233-1993 "Sulfuric Acid Anodizing Process of Aluminum and Aluminum Alloys".
[0033] 2) Sol preparation
[0034] First, add 5ml of anhydrous acetic acid to 300ml of anhydrous methanol at room temperature, then slowly add 400ml of γ-glycidyl etheroxypropyltrimethoxysilane, stir evenly for 1 hour, and obtain an organosiloxane sol. At the same time, 8 ml of anhydrous acetic acid and 80 ml of zirconium propoxide were poured into 100 ml of anhydrous methanol, and stirred evenly for 1 hour to obtain a metal alkoxide sol. Under stirring, the organosiloxane sol and the metal alkoxide sol were mixed, and stirred at room temperature for 2 hours to obtain a mixed sol.
[0035] Then, at room temperature, a solution containing 5% chloroauric acid in anhydrous methanol was prepared.
[0036] Finally, und...

[0043] 1) Pretreatment of aluminum alloy samples
[0044] The pretreatment of the aluminum alloy samples is carried out according to the provisions of the aviation industry standard HB / Z 233-1993 "Sulfuric Acid Anodizing Process of Aluminum and Aluminum Alloys".
[0045] 2) Sol preparation
[0046] First, add 5ml of anhydrous acetic acid to 300ml of anhydrous methanol at room temperature, then slowly add 500ml of 3-glycidyl etheroxymethyldiethoxysilane, stir evenly and continue for 1 hour to obtain an organosiloxane sol . At the same time, 5 ml of citric acid and 50 ml of tetrabutyl titanate were poured into 100 ml of anhydrous methanol, and stirred evenly for 1 hour to obtain a metal alkoxide sol. Under stirring, the organosiloxane sol and the metal alkoxide sol were mixed, and stirred at room temperature for 2 hours to obtain a mixed sol.
[0047] Then at room temperature, a solution containing 4% chloroauric acid in anhydrous methanol was prepared.
[0048] Finally, und...
Embodiment 3
[0055] 1) Pretreatment of aluminum alloy samples
[0056] The pretreatment of the aluminum alloy samples is carried out according to the provisions of the aviation industry standard HB / Z 233-1993 "Sulfuric Acid Anodizing Process of Aluminum and Aluminum Alloys".
[0057] 2) Sol preparation
[0058] First, at room temperature, 5ml of anhydrous acetic acid was added to 300ml of absolute ethanol, and then 600ml of γ-glycidyloxypropyltrimethoxysilane was slowly added, stirred evenly and continued for 1 hour to obtain an organosiloxane sol. At the same time, 8 ml of anhydrous acetic acid and 60 ml of zirconium n-propoxide were poured into 100 ml of anhydrous methanol, and stirred evenly for 1 hour to obtain a metal alkoxide sol. Under stirring, the organosiloxane sol and the metal alkoxide sol were mixed, and stirred at room temperature for 2 hours to obtain a mixed sol.
[0059] Then, at room temperature, a solution containing 6% chloroauric acid in anhydrous methanol was prepar...
