Abstract
The adverse operating environments encountered by
marine gas turbine components has necessitated the
development of various protective coating systems.
Diffusion aluminide coatings have been used successfully for
many years to enhance the hot corrosion resistance of
turbine blades and vanes. Recently, it has been found that
by modifying these standard aluminide coatings with a thin
platinum underlay, significant improvements in high
temperature corrosion resistance can be achieved. Using a
laboratory furnace specifically modified to reproduce hot
corrosion attack morphologies, the effects of selected
platinum-aluminide coating deposition variables were
investigated on two nickel-base superalloy substrates ( IN-
100 and IN-738),
