Ultra-Strong High-Temperature Bonding of Titanium to Ceramic Materials
Agency / Branch:
DOD / MDA
Currently the IRBAS ceramic radomes of the PAC-3 missiles are being attached at the Lockheed Martin Missile & Fire Control Corp (LMMFC) using an adhesive bonding process that is not capable to sustain high mechanical and thermal stresses required for this application. Conventional high-temperature brazing in a furnace cannot be applied due to the large size of the components being bonded and high cost associated with it. A furnaceless bonding process was previously proposed by BAE Systems Emerging Technologies. However this process has not been implemented by LMMFC due to insufficient bond strength resulting from material interface issues. Integrated Micro Sensors Inc. (IMS) proposes an efficient laser-assisted process for fabrication of Micro Column Arrays (MCA) on pre-bonded surfaces, which will allow for significant improvement of the furnaceless brazing process developed at BAE Systems. The objective of this project is to bring the IMS MCA laser ablation process to maturity and demonstrate commercial integration of this process with BAE brazing processes using LMMFC tooling and PAC-3 MSE Radome hardware. As a result of the Phase II project Integrated Micro Sensors Inc. will demonstrate and test a pre-commercial prototype of a PAC-3 missile IRBAS ceramic radome brazed to a Ti alloy attachment ring.
