Abstract: In order to study the effect of glass powder on the structure of polysilazane ceramic coating, the pyrolysis processes of polysilazane and polysilazane/glass powder mixture were studied by TGA and FTIR. The results show that the pyrolysis trend of the samples before and after adding glass powder is basically the same. In the whole pyrolysis process, the polysilazane will release gas, in which ammonia will be produced when the temperature is below 500 ℃ and methane will be mainly released at 500—700 ℃. Glass/ceramic composite coating was prepared on TP 347 substrate by dip coating, and its micro morphology was characterized by SEM. The results show that glass powder can significantly improve the critical thickness of the coating. In order to prevent the composite coating from forming large pores after sintering, the sintering temperature can be increased as high as possible under the allowable substrate temperature.
