abstract = {Testing of the corrosion resistance of environmental
barrier coating (EBC) systems is necessary for developing
reliable coatings. Unfortunately tests under realistic gas
turbine conditions are difficult and expensive. The
materials under investigation as well as parts of the test
setup have to withstand high temperatures (>= 1200 degrees
C), high pressure (up to 30 bar) as well as the corrosive
atmosphere (H2O, O-2, NOx). Therefore most lab scale
test-rigs focus on simplified test conditions. In this work
water vapor corrosion testing of EBCs with a high velocity
oxy fuel (HVOF) facility is introduced which combines high
temperatures and high gas velocities. It leads to quite high
recession rates in short periods of time, which are
comparable to results from literature. It was found that
high flow velocities can easily compensate low gas
pressures. HVOF-testing is a simple and fast way to measure
the recession rate of an EBC-system. As proof of concept the
recession rates of an oxide/oxide CMC with and without EBC
were measured.},
