Sandblasting (SB) of the surface of the AlSi10Mg aluminium alloy is performed after additive synthesis by selective laser melting (SLM) and additional T6 heat treatment (annealing at a temperature of 520 ± 10°C for 1.5 hours followed by water quenching and subsequent artificial ageing at a temperature of 150 ± 10°C for 10 hours followed by air cooling). A standard SB scheme with abrasive Al2O3 particles in air is used for 10–120 s. As shown, the main differences between additively printed and heat-treated samples after SB relate to their mass loss, microhardness, surface roughness and morphology, and residual stresses. The microstructure, phase and chemical compositions are studied in detail, and the hardening mechanisms are discussed.
Key words: additive manufacturing, selective laser melting, sandblasting, morphology, deformation, AlSi10Mg alloy.
