. The conclusions are as follows, the thickness of the as-prepared ZrB2-SiC based composite ceramic coating is about 200 μm. The densification and the anti-oxidation properties of the coating can be improved by the addition of Si3N4 and MoSi2, effectively. While the anti-oxidation properties of the coating can not be improved by the addition of TaC effectively at 900 ℃. At 900 ℃, the oxidation process......
