The primary objectives of this research effort were to synthesize and characterize several kinds of ceramic films, and to develop in situ techniques for monitoring the growth process of these coatings. Chemical vapor deposition was used for film growth. An FT-IR spectrometer was configured for in situ monitoring of chemical reactions and film composition during growth. The work contributes to the Air Force structural materials program, particularly to the area of improved protective coatings for glass and related materials. Capabilities reported include the ability to monitor chemical composition during thin film growth. Chemical species on the surface of a growing diamond film on a sapphire substrate were monitored in situ using grazing incidence infrared reflectance spectroscopy. Continuation of this work will evaluate the use of polarization modulation reflectance for in situ monitoring. This work will assist in the development of new materials for coatings and the establishment of new research capabilities in the fabrication of nanomodulated ceramicoxide coatings on a variety of materials of interest to the Air Force.
