Abstract
An oxidation protective coating of SiBCN(O) is prepared by slurry method, using polyborosilazane (PBSZ)-ethanol solution as the precursor. The dense and uniform coatings are obtained by pyrolysis and sintering at 1573K. The sintering temperature is significantly reduced and the densification is improved by introducing oxygen. The coating shows high oxidation protecting performance during the thermal shock between 1773K and room temperature for 10 cycles. The oxidation mechanism of the coating is studied and the results show that two stages are included: the relatively stable stage and the weight loss stage.
