AbstractPure Al with high laser reflectivity is essentially incompatible with laser powder bed fusion. The retention of a large number of unmelted particles leads to inferior geometrical quality and mechanical properties of printed pure Al parts. In the present study, we propose decorating Al with a small amount of high laser absorbing Co nanoparticles on the surface of Al powders to reduce laser reflectivity and improve printability. The experimental results confirmed that the approach was very effective. The near homogenous dispersion of Co slightly modified the surface chemical composition and roughened the powder surface. This approach completely melted the particles and eliminated the internal pores, thereby favorably tuning the geometrical dimensions. Additionally, the introduction of Co provided solid solution strengthening and precipitation hardening via dispersion of second-phase Al9Co2 with a coherent interfacial relationship with the Al matrix. The tensile properties of printed Al parts were comparable to commercial medium-strength Al alloys at an optimal Cocontent of 0.5 wt.%.
