The influence of duplex post-processing treatment on the surface characteristics of additively manufactured AlSi10Mg alloy is studied. Duplex treatment consists of post-heat treatment and shot-peening processes, resulting in enhanced surface finish and hardness compared to as-printed samples. The multi-scale roughness parameters were determined, such as amplitude and spatial parameters and statistical functions. Shot peening decreased the amplitude parameter values by ~ 50% more than as-printed samples. The spatial parameter analysis indicated that the SP process transformed the surface more uniformly than the as-printed samples. The surface under the SP with peening pressure (6 bar) condition has non-uniformity compared with the surface under peening pressure with 3 bar condition due to higher peening pressure resulting in strong directional textures. The material ratio curves revealed uniform surface morphology development due to shot peening and fewer surface irregularities than the as-printed samples. [ABSTRACT FROM AUTHOR] |
