Abstract
Marine gas turbines face many adverse conditions such as
reduced fuel quality and a salt environment which present
the sulfur, chloride, and sulfates required to initiate and
propagate hot corrosion. A particularly severe type of hot
corrosion is low temperature hot corrosion (LTHC) encountered
at the low temperatures (600-750°C) used for low power
destroyer operations. Plat inu m-aluminides have demonstrated
great success as protective coatings which delay the onset
of hign temperature hot corrosion attack (80 0- 1000°C) .
Chromium is known to provide good LTtiC resistance. The
effect of chromium addition to platinum-aluminide coatings
was investigated using two different nickel-base superalloys,
IN-738 (16% Cr) and IN-100 (10% Cr).
