The corrosion behavior of Fe-containing directionally solidified (DS) and centrifugally cast (CC) Al-Si-Cu-Zn alloys with either Co or Ni additions has been investigated. Electrochemical and immersion corrosion methods were used to investigate the corrosion behavior in 0. 6 M NaCl after short (1-h) and long (30-day) exposure periods. https://www.popularfilm.blog/
