| Summary | 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 Coating evaluation and analysis |
| Advantage | 1. Applications ① Thermal barrier coating for next generation aircrafts and gas turbines ② Parts exposed to ultra high temperature and ultra light parts for military purposes 2. Benefits ① High temperatue, thermal barrier coating now locally procurable. Leadership role in parts used in extreme conditions ② Technology independence of space vehicle technologies by improving efficiency and lifetime of rocket engine thrust chamber |
