Metal matrix composites (MMCs) play a crucial role in the aerospace, automotive and mineral processing industries. The properties of aluminum (AMC) that are renowned for their high strength, good stiffness excellent thermal conductivity can be enhanced by incorporating various reinforcements. In this investigation, Al7075 alloy with TiC (3, 6, 9 wt.%) reinforcements was processed via stir casti...

Extrusion at 450?C of hot compacted premixed aluminium alloy powder 7075 resulted in full density and banded microstructure with the average transverse grain size 13.6 ?m after T6 heat treatment. It increased mechanical properties to yield tensile stresses 457 492 MPa, respectively elongation 6.4 %. These meet requirements ASTM standard ASM for 7075T6 conventionally manufactured similar chemica...

In this work, polypyrrole/ZnO nanocomposite (PPy/ZnO NC) was produced through synthesis of polypyrrole polymer in the presence of ZnO nanoparticles. The corrosion behavior of polyvinyl butyral coatings without and with different weight percentages of nanocomposite on the surface of 7075 Al alloy was investigated in 3.5% NaCl solution at different immersion times using electrochemical impedance ...

In the present study, corrosion behavior of aluminum Al-7075 tempered (T-6 condition) alloy was evaluated by immersion testing and electrochemical in 1.75% 3.5% NaCl environment at acidic, neutral basic pH. The data obtained both tests (potentiodynamic polarization impedance spectroscopy tests) that rate specimens is minimum for pH=7 condition solution due to formation dense well adherent thin ...
