Abstract Scope |
Cold spray is a solid-state powder deposition process in which particles are accelerated via a supersonic gas flow to impinge on and deposit onto substrates. Cold spray metal onto metal have been widely studied, but few studies have been devoted to deposition of metal onto polymer composites. One of the main problems reported is the erosion of fiber and thermoset substrates. To avoid erosion of the carbon fiber reinforced polymer (CFRP) and achieve cold-weld of impinging particles, a bond layer (BL) is required. There is a need to engineer a bond layer compatible with cold spray and develop understanding of the quantitative effects of bond layer microstructure on coating adhesion. Adhesion of cold-sprayed coating is determined by the BL-CFRP, particle-BL and particle-particle bonding. Interface engineering of the bond layer microstructure can enable hybrid process routes to impart metal-like durability on composites for light-weighting of metallic components and facilitating rapid repair. |
