Transport Phenomena Studies by Computational Simulation in Structural Materials Processing

Abstract

Chemical vapor deposition (CVD) is one of the most important techniques for the processing of structural materials. It is extremely versatile in that a wide range of materials and coatings is done by CVD, perhaps more than by any other technique. The process is flexible enough to accommodate a variety of sizes and shapes of objects to be processed and allow continuous change of composition of the material or coating. In this report we discuss the application of CVD processes to structural materials'. The classification 'structural materials' here is based on the end use being in aerospace, mechanical and related applications (as opposed to electronics materials) and hence covers coatings and high temperature aerospace materials such as composite structures, ceramic matrix composites (CMC), functionally gradient materials (FGM), etc. Representative examples are SiC (fiber, coating), Si3N4, BN, other carbides and nitrides, composites such as SiC-SiC, carbon-SiC, carbon-carbon, and carbon-BN.
