Flow And Transport In Combustion Flame Cvd Of Diamond Thin Films


This paper presents a numerical model to understand and predict diamond film deposition by combustion film assisted chemical vapor deposition method, which is perceived as a suitable technique to produce synthetic diamond under micro-gravity conditions. In this method, diamond thin film is deposited with a laminar, premixed C2H2/O2 flame. The effect of two major operating parameters, substrate-to-nozzle distance and premixed gas composition, on the rate of diamond deposition was investigated. Deposition rate increases with higher C2H2/O2 ratio, and decreases with increasing substrate-to-nozzle distance. This observation is explained with flow and transport characteristics of the flame. © 2000 by the American Institute of Aeronautics and Astronautics, Inc. All rights reserved.
