Abstract
The corrosion resistance of MOCVD Al2O3 coating system was investigated to protect a
TA6V Alloy under hot salt corrosion conditions: This coating was corroded with a salt deposit
without mechanical loading at 480°C during 100 h. Corrosion products formed in salted areas were
studied by Energy Dispersive Spectroscopy (EDS). Although all coated specimens were damaged
with corrosion products presence in salted area, Al2O3 coatings showed the lowest salt damage on
titanium substrate after a metallographic cross section observation compared to uncoated ones. As
well as these interesting experimental results, coated specimens exhibit a good adherence on
titanium substrate
