Abstract Scope |
This study focuses on investigating the corrosion behavior of different percentage of Aluminium doped CoCrFeMnNi high entropy alloys (HEAs). HEAs have shown promising mechanical properties and unique microstructural traits, making them potential candidates for corrosion-resistant applications. CoCrFeMnNiAlx samples were prepared using the powder metallurgy method to achieve a homogenous microstructure and sintered under argon atmosphere at 600°C for 2 hours. Immersion tests in a 3.5% NaCl solution were carried out to calculate corrosion rates and potentiodynamic polarization technique was used to evaluate the corrosion behavior. Preliminary findings indicate that higher aluminum content in the HEAs leads to improved corrosion resistance which also form more protective passive films on their surfaces, contributing to enhanced corrosion resistance and changes in mechanical hardness. These results provide valuable insights into the corrosion behavior of CoCrFeMnNiAlx alloys that can be used for specific corrosion-resistant applications such as aerospace, marine, and high-performance materials. |
