| Abstract: | This paper describes chemical vapor deposition (CVD) process of depositing TiC coatedmaterials by the TiCl4-CH4-H2 system, the influence of coating conditions on coating microstructure, deposition rate and the influence of substrates (Mo, graphite and 316LSS) oncoating growth. The experimented relationship between coating thickness and process conditions is given. For TiC / graphite, TiC / Mo, TiC / 316LSS, the failure mechanism of highpower density electron beam thermal shock and thermal fatigue is discussed, the possibility ofusing them as the first wall of current operating Tokamak devices is analysed. |
