Brittle particle cold spray (bpcs) technology for the deposition of nanostructured and microstructured multicompound composite materials

Abstract

Brittle Particle Cold Spray (BPCS) deposition technology is controlled primarily by particle size distribution and particle shapes. Therefore, composite materials with unique material compositions and functional properties can be supersonic cold spray deposited by combining powders of the same or different functional brittle material types that have the same particle size distribution or by combining powders with complimentary particle size distributions that when mixed together produce the required particle size distribution for successful brittle particle cold spray deposition of the mixed compound. High temperature capability ceramic and carbon micro and nano fibers can also be incorporated into the cold spray material powder mix that when cold spray deposited produce random fiber Ceramic Matrix Composite (CMC) materials for high temperature thermal protection systems and other applications. Nanostructured composite and multicompound materials can also be supersonic cold spray deposited.
