Abstract

Corrosion behaviors of AlCrFeTi and AlCrFeTiMo multi-principal elements coatings in 0.5 ~ 1 × 10-6 wt. % oxygen containing liquid lead bismuth eutectic (LBE) was investigated, static LBE immersion tests were conducted at 500 °C, 550 °C and 600 °C up to 2000 h. Both AlCrFeTi and AlCrFeTiMo coatings had experienced phase transformation from amorphous to BCC. Bi-layered oxide scales were formed on AlCrFeTi coating which consist of outer Fe/Cr mixed oxides and inner Al/Ti oxides, the interior Al/Ti oxide layer was strengthened with temperature raising and amorphous features of oxide scales were confirmed. The addition of Mo improved the system stability at elevated temperature but degraded the corrosion resistance of coating. Underlying corrosion mechanism of AlCrFeTi and AlCrFeTiMo coatings were discussed.
