Abstract

Deposits are made by spraying powder particles at high speeds onto a substrate in the cold spray (CS) technique. Cold spray (CS) is the only thermal deposition technique in which particles are deposited below their melting temperature, making it a solid-state processing technique. Coatings created using CS have distinct properties than coatings created using other technologies, which could make CS a viable option for self-standing component repair and possibly fabrication. But, a particle's deformation behaviour is influenced by a variety of material and process parameters which are determined by powder properties, geometric parameters, and processing parameters. Changing any of these parameters causes the deposit's microstructure to evolve and, as a result, the deposit's mechanical characteristics to alter. The purpose of this study is to study the mechanical properties of 7075 al-t6 cold sprayed with 6065 aluminum powder. Important factor such as coating temperature, pressure, coating thickness, particle size which affect the resistane, physcial and mechanical properties of 7075 Al-T6 are stated. Impact testing, tensile strength testing, rockwell hardness testing, surface roughness testing and focus ion beam are used to assess the effectiveness of the CS coating process.
