On the surface integrity of additive manufactured and post-processed AlSi10Mg parts
Abstract
The research centres on the evaluation of surface integrity of AlSi10Mg parts produced via laser-based powder bed fusion (LPBF) process,<br/>followed by vibratory surface finishing. The alloy is chosen for its applications in lightweight components used in electronic packaging,<br/>automotive and aerospace sectors. Initial experiments involve optimisation of key LPBF process parameters by analysing the surface roughness<br/>and density data of the built parts. A Taguchi L18 orthogonal array is used for the optmisation trials with variations in the laser power (P), beam<br/>scanning speed (v), hatch spacing (H) and island size (I). Latter experimental phase deals with microhardness and microstructure assessment of<br/>heat treated LPBF specimens that are produced using the optimised LPBF parameters, i.e. P: 250 W, v: 1500 mm/s, H: 75 μm and I: 2 mm.<br/>Microhardnesses of the annealed samples reduce by ~12% with respect to the as-built parts and the values remain almost unchanged from the<br/>annealed state following solution treatment and ageing. The fish-scale like melt-pools observed on the unheat treated samples begin to fade off<br/>in the annealed specimens and completely disappear after solution treatment and ageing, with silicon particles dispersed all over the aluminium<br/>matrix. The final experimental phase involves vibratory surface finishing of the as-built LPBF parts using a vibrating ceramic media mixed<br/>with different acid and amine based liquid compounds for 1-6 hours, followed by vibrating in a maize based media for another 1-6 hours.
