چکیده
Actual marine atmospheric pre-corrosion behavior and its effect on the fatigue performance of 7075-T73 aluminum alloy were studied by means outdoor exposure testing testing. The surface cross-sectional microstructures specimens after different numbers days analyzed. Localized pitting, intergranular exfoliation corrosion occurred during in a atmosphere. degree severity increased with increasing duration exposure. effects Fe-rich constituent particles (Al23CuFe4) grain boundary precipitates (MgZn2) discussed. In addition, when time was from 0 to 15 days, average life decreased dramatically about 125.16 × 104 cycles 16.58 cycles. As further 180 slowly 6.21 fracture characteristics mechanism also

متن کاملSurface Characterizations of Fretting Fatigue Damage in Aluminum Alloy 7075-T6 Clamped Joints: The Beneficial Role of Ni–P Coatings
This paper aims to characterize the surface damage as a consequence of fretting fatigue in aluminum alloy 7075-T6 plates in double-lap bolted joints through XRD, surface profilometry, and SEM analyses. The main focus was on the surface roughness and chemical phase composition of the damaged zone along with the identification of fretting fatigue crack initiations over the surface of the material...
متن کاملInfluence of Temperature on Corrosion Behavior of 2A02 Al Alloy in Marine Atmospheric Environments
The corrosion behavior of 2A02 Al alloy under 4 mg/cm² NaCl deposition at different temperatures (from 30 to 80 °C) has been studied. This corrosion behavior was researched using mass-gain, scanning electron microscopy-SEM, laser scanning confocal microscopy-LSCM, X-ray photoelectron spectroscopy-XPS and other techniques. The results showed and revealed that the corrosion was maximal at 60 °C a...
