Thermal Barrier Coating for Space Launch Vehicles 사업화 기술의 기술분야, 기술소개, 특징 및 활용방안, 첨부파일을 표시합니다.

Field New Material
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
