Abstract Scope |
Cold spray depositions are an increasingly relevant repair technology for light metal parts in maritime and aerospace applications. As helium gas becomes costlier to acquire and use, nitrogen gas provides a viable alternative for use as a carrier gas for cold spray depositions when combined with metal matrix composites. The metal matrix composites were deposited using high pressure cold spray with three different combinations of ceramic media and aluminum 6061 matrix material. Residual stress profiles were compiled using x-ray diffraction, electrochemical milling, and laser confocal profilometry. Grain size, phase composition, and crystallographic orientation was collected using scanning electron microscopy and electron backscatter diffraction. Mechanical testing was carried out using three lug shear, adhesion testing, and tensile testing of the coating-substrate system. |
