英文摘要	A La2O3 modified ZrB2-SiC coating on SiC coated graphite was prepared by slurry brushing and subsequent siliconizing. The coating exhibited much better oxidation and cracking resistances compared with ZrB2-SiC coating. The weight gain of ZrB2-SiC-La2O3 coated sample was 3.85 x 10(-3) g/cm(2) after isothermal oxidation at 1800 degrees C for 30 min and it was 6.49 x 10(-3) g/cm(2) after short cyclic oxidation at 1500 degrees C for 30 times, while they were 4.25 x 10(-3) g/cm(2) and -7.12 x 10(-3) g/cm(2) for the ZrB2-SiC coated sample, respectively. The good comprehensive performance of La2O3 modified ZrB2-SiC coating was attributed to the continuous La dissolved oxide scale with lower oxygen permeability and lower internal stress.
