THE INVESTIGATION ON INTERFACE OF THE OXIDATION RESISTANT COATING OF CARBON-CARBON COMPOSITE

The component and processing of the carbon-carbon (C/C) composite with diffusion type coating have been studied,and the results of the oxidation resistant performance and dynamic environment tests are given.It has been shown by analyzing the microstructure,that SiC coating formed by the reaction on C/C composite surface is the combination of chemical convetting coating and C/C composite,which is gradient interface of which components are continuously changing where it constructs the functionally gradient material,makes SiC coating have excellent performances.
