This research focuses on metal additive manufacturing (MAM) and examines the impact of alloying materials anodized produced layer, placing particular emphasis its use in construction NARSSCube satellite's frame. To enhance AA6061-T6 Al alloy's mechanical physical qualities, Mg, Mn, Si, Cr concentrations were changed. As a result, seven different alloys cast, their characteristics assessed. It is essential to anodize aluminum alloy H2SO4 solution order produce an oxide film (AOF) that increases corrosion wear resistance. study looked into how chemical composition alloy, particularly affected production nano hard (NHAOF) at fixed anodization conditions 4 °C 20 V. Calculations made thickness variation various operating voltages throughout anodizing process. The differences NHAOF investigated using optical scanning electron microscopes. Finally, with low Mn Wt.% (0.005 wt% S6) °C, V, duration period 120 min 10 % coating highest (53 μm) high-performance attributes. An increase hardness ratio, resistance plastic indentation, elastic recovery are all results surface's harder (5.86 Gpa) than un-anodized sample's (1.18 surface.
