For this study, a fixed high-end primary parameter set with respect to gas pressure and temperature was selected for depositing Al6061 powder feedstock on Al6061-T6 substrate sheets. The influences of different parameter variations on spray deposit build-up and performance were investigated by evaluations of deposit efficiency, deposit microstructures, porosities, deposit hardness, and electrical conductivity.
