Effect of Cold-Spray Parameters on Surface Roughness, Thickness and Adhesion of Copper-Based Composite Coating on Aluminum Alloy 6061 T6 Substrate

A solid-state cold-spray technique was employed for depositing the copper-coated graphite reinforced copper-based composite coatings on aluminum alloy 6061 T6 substrate under different process parameters. The optimum parameters of cold-sprayed were predicted in terms surface roughness, thickness and adhesion. roughness measured using a 3D profilometer, element constitution detected by an optical microscope scanning electron furnished with energy-dispersive spectral analyzer adhesion scratch test method. microstructures deposited also observed microscope. results show that when coating is not oxidized dense, at 800 °C, 5.5 MPa, possesses lowest maximum highest among coatings. In addition, are all linear particle velocity.
