| Abstract: | An environmental barrier coating system was applied on SiCf/SiC composite specimens with the silicon bond coat and mullite intermediate coat sprayed using APS processes and the ytterbium silicate topcoat sprayed using a PS–PVD process.The sprayed environmental barrier coating system is dense in microstructure and the PS–PVD ytterbium silicate topcoat possesses lamellar structure with a porosity less than 1%.The static oxidation,cyclic oxidation,water vapour corrosion and thermal impact resistances of the environmental barrier coating system were investigated.It was demonstrated that the environmental barrier coating sprayed on the SiCf/SiC composite specimens had a desirable oxidation resistance as it kept intact with no obvious evidence of spallation observed after 100h static oxidation,100h cyclic oxidation test at 1200℃and 1300℃.Moreover,the coating had a thermal impact resistance life more than 100 cycles as heated to a high temperature of 1300℃by a hot gas stream and it had a preferable corrosion resistance at 1200℃in an environment containing 15%H2O water vapour. |
