Nozzle is one part of rocket which works at high temperatures. The S45C steel is applied for material base of nozzle. This material was coated by Thermal barrier coating (TBC) of Al2O3-SiO2. The mixing ratio of ceramic oxide were 80% Al2O3 - 20% SiO2; 70% Al2O3 - 30% SiO2, and 60% Al2O3 - 40% SiO2. Coating process is conduct by Flame Spray. The microstructure, phase and adhesion strength of TBC examined by Scanning Electron Microscope(SEM), X-Ray Diffraction and pull off test. The results shown that mullite formed at mixing ratio 70% Al2O3 - 30% SiO2. The reduction of TBC thickness was reduced to 40% of the initial thickness after heating. The adhesive strength decreases with increasing of SiO2 composition.
