Abstract The scanning vibrating electrode technique was employed to monitor the in situ localised electrochemical activity on aluminium alloy 2024-T3 at free corrosion potential aggressive NaCl solutions with and without inhibitors 2-mercaptobenzimidazole (MBI) octylphosphonic acid (OPA). MBI is a very effective inhibitor against pitting corrosion, even chloride environment reservoir of MBI. In...

Since their development, third-generation aluminum–lithium alloys have been used in aeronautical and other applications due to good properties, replacing conventional Al-Cu Al-Zn resulting an increase payload fuel efficiency. The aim of this work was investigate the influence different heat treatments on electrochemical corrosion behavior AA2055 AA2024 presence three electrolytes at room temper...

Günümüzde savunma, havacılık ve uzay sanayinde, otomobil sanayiinde çeşitli endüstriyel alanlarda alüminyum alaşımları imalatı büyük önem kazanmıştır. Üretim aşamasında malzemelerin birleştirilmesinde kullanılan ergitmeli kaynak yöntemleri problemli zordur. Ayrıca, bu alaşımların birbirine benzemeyen metaller ile geleneksel birleştirme katı hal kadar cevap verememektedir. Alüminyum alaşımlarını...

In this work some organic natural products were studied, namely tannic acid, gallic mimosa tannin and chestnut tannin, as potential green corrosion inhibitors of the aluminium alloy AA2024-T3. The anodizing treatment was performed in a solution referred compounds diluted sulfuric acid. electrochemical impedance spectroscopy potentiodynamic polarization to assess sealing quality protection grant...

This paper proposes a finite element model implemented in ANSYS using Lagrangian formulation to assess heat generation and friction dynamics of stir welding process on AA2024-T3 aluminum plates. For that aim, the is enriched by estimating temperature-dependent coefficient theoretical relationships, considering multilinear isotropic hardening equation as plasticity representing material. Both qu...
