A Galvanic Corrosion Approach to Investigating Chromate Effects on Aluminum Alloy 2024-T3
The effects of chromate treatment on the corrosion of an aluminum/copper aircraft alloy were examined with a galvanic corrosion apparatus composed of two electrodes and a zero resistance ammeter. Combinations of pure Al, pure Cu, and AA2024-T3 electrodes were immersed in 0.1 M NaCl solution, which was saturated with air, O2 , or argon. Selection of electrode material or differential aeration re...
متن کاملCORROSION RESISTANT SOL–GEL COATING ON 2024-T3 ALUMINUM
The inherent reactivity of the Al–Cu alloys is such that their use for structural, marine, and aerospace components and structures would not be possible without prior application of a corrosion resistance system. Historically these corrosion resistance coatings were based on the use of chemicals containing Cr (VI) compounds. Silane coatings are of increasing interest in industry due to th...
متن کاملEffects of Anodizing Parameters in Tartaric-Sulphuric Acid on Coating Thickness and Corrosion Resistance of Al 2024 T3 Alloy
2024 T3 is one of aluminium alloys which are widely used in the aircraft structures. Anodizing of alluminium alloy in tartaric-sulphuric acid (TSA) electrolyte is developed to obtain more environmentally-friendly process and to produce anodize layer with better corrosion resistance. In this research work, the influences of anodizing parameters of Al 2024 T3 in TSA on the thickness, weight and c...
متن کاملLocalised corrosion in aluminium alloy 2024-T3 using in situ TEM.
An approach to carry out chemical reactions using aggressive gases in situ in a transmission electron microscope (TEM), at ambient pressures of 1.5 bar using a windowed environmental cell, called a nanoreactor, is presented here. The nanoreactor coupled with a specially developed holder with platinum tubing permits the usage of aggressive chemicals like hydrochloric acid (HCl).
متن کاملplasma electrolytic oxidation of 2024-t3 aluminum alloy and study of its corrosion resistance and tribological behavior
in this study, plasma electrolytic oxidation of 2024-t3 aluminum alloy was investigated. the electrolyte used in this investigation was an alkaline solution containing additives of silicate, phosphate, potassium hydroxide and glycerin. a conventional dc power source with a low applied voltage was employed. corrosion resistance of the oxide layer was investigated by means of tafel plots and elec...
