Gordon,
Metco suggested that we consdier the 2043 or 2042 coatings. While
they say that they are only good to 1800F in their literature the
feel we can likely get by with them for a limited test time with
our gaspath temp in the 1900F range. Not optimal for a production
application, but it should work for a short term demo. The
substrate temp shouldn't be over 1800 and they felt comfortable
with that.
