This technology is about ensuring the durability of the thermal barrier coating layer after
over 10 times of testing lasting over a total of 600 seconds, including the longest combustion of
150 seconds per test, in a thermal environment equivalent to that of the actual thrust chamber of
a liquid fuel rocket engine (combustion pressure of 6-8MPa, O/F ratio of 2.4-2.5, total flow rate of 20-30 kg/s).
Constituting technologies
MCrAlY bond coating, VPS/APS coating
ZrO2 ceramic thermal barrier coating
Cylinder/nozzle interior coating, actual product coating
Fabrication and mixing of spray powder with low thermal conductivity
FGM-TBC coating
