Fiber Interface Coatings - CCI can deposit both the standard carbon and boron nitride fiber interface coatings for use in ceramic matrix composites. In addition, multi-layered fiber interface coatings for advanced high temperature composites have been developed. One was based on a C-SiC-TiC trilayer system. Multiple layers of this trilayer system have also been examined. The second was a Ti₃SiC₂ coating. Both interface coatings were developed for ceramic matrix composites to be used in high temperature propulsion component applications. Both these systems demonstrated outstanding oxidation resistance for both the SiCf/SiC and Cf/SiC composite systems while providing the desired mechanical properties. CCI's automated process control system enables a high level of reproducibility.
