Abstract In this study, the possibility of obtaining a corrosion indicator from time series electrochemical impedance spectra acquired during immersion intact organic coatings was inspected. To generate wide distribution in performance, with different pigment volume concentrations were applied on AA2024‐T3 and cold‐rolled mild steel tested four electrolytes for exposure times. The relative rank...

Plasma electrolytic oxidation (PEO) was applied to functionalise the surface of AA2024 alloy. A potassium titanium-oxide oxalate dihydrate based aqueous electrolyte used, which allowed direct formation a TiO2 layer on aluminium alloy substrate. The effect PEO treatment time and additional presence anatase particles in solution its properties (corrosion, wear photocatalytic activity) were invest...

The influence of high energy-ball milling (HEBM) on corrosion and hardness age hardening aluminum alloys was investigated. Nanocrystalline (AA2024, AA6061 AA7075) were produced by HEBM pre-alloyed powder subsequent cold compaction under uniaxial pressure 3 GPa. Cyclic potentiodynamic polarization immersion tests conducted in 0.6 M NaCl solution which revealed significantly increased pitting pro...

This study deals with fatigue crack growth prediction for thin sheet AA2024 specimens residual stresses introduced through laser shock peening and heating treatments. Different weight functions are used to calculate the stress intensity factor due presence of stresses. A superposition principle is by calculating total considering applied loads The predicted using Paris' law based on effective r...

In this study, it was aimed to produce Al-matrix composite materials with B4C-SiC and B4C-Y2O3 particle reinforcement using the Powder Metallurgy (PM) method. composites in which were used at different sizes ratios, AA2024 powders selected as matrix material. The homogeneously mixed compacted room temperature under a pressure of 525 MPa. raw specimens sintered by keeping them temperatures for 4...
