Title: Development and Evaluation of Oxidation Protective Coatings for Carbon-Carbon Composites
Agency / Branch: DOD / USAF
Contract: FA8201-05-C-0071
Award Amount: $749,994.00


Aircraft brake pressure plates made of carbon-carbon composites are subjected to very high heat over 1000 degrees F causing oxidation, thus limiting the life span. Oxidation protective coating system needs to be developed that can substantially improve the performance characteristics and life span. In Phase I, UES, Inc. has demonstrated the feasibility of depositing silicon and boron based multilayer coating system using physical vapor deposition methods. Formation of SiC by subsequent heat treatment together with a boron containing coating clearly showed excellent oxidation resistant properties of the coatings. In Phase II, UES proposes to optimize the coating process for fast deposition and formation of SiC and boron containing glasses for improved oxidation and environmental protection. Optimized, well-adherent coatings will be subjected to lab-scale simulated exposure tests up to 2000 degrees F. Scale up of the coating process for actual brakes will also be pursued in Phase II.
