“…The previous schematic ( Figure 1) is a depiction of the LM process. Although LM is typically used for the fabrication of parts from metallic powders (Abe et al, 2001;Bertrand et al, 2007;Li et al, 2011;) this AM technique was identified as potentially being able to process the regolith ceramic material.…”

Purpose -The purpose of this paper is to investigate the effect of the main process parameters of Laser Melting (LM) type Additive Manufacturing (AM) on multi layered structures manufactured from JSC-1A Lunar regolith (Moondust) simulant powder.Design/methodology/approach -Laser diffraction technology was used to analyse and confirm the simulant powder material particle sizes and distribution. Geometrical shapes were then manufactured on a Realizer SLM™ 100 using the simulant powder. The laserprocessed samples were analysed via Scanning Electron Microscopy (SEM) to evaluate surface and internal morphologies, Energy-dispersive X-ray Spectroscopy (EDS) to analyse the chemical composition after processing and the samples were mechanically investigated via Vickers micro-hardness testing.Findings -A combination of process parameters resulting in an energy density value of 1.011 J/mm 2 allowed the successful production of components directly from Lunar regolithsimulant. An internal relative porosity of 40.8 %, material hardness of 670 ± 11 HV and a dimensional accuracy of 99.8 % were observed in the fabricated samples. Originality/value -This research paper is investigating the novel application of a PowderBed Fusion AM process category as a potential on-site manufacturing approach for manufacturing structures/components out of Lunar regolith (Moondust). It was shown that this AM process category has the capability to directly manufacture multi-layered parts out of Lunar regolith, which has potential applicability to future moon colonization.

The laser surface treatment of magnesium alloy was studied. ZrO2 was used as sintering ceramics, and its corrosion resistance was verified. Appropriate laser parameters were proposed for homogeneous solidification of the sintered layer. The chemical compositions of the sintered layer were analyzed with laser-induced breakdown spectroscopy. Na2SO4 was used for a corrosion test, and the resistance of the sintered sample was confirmed. The microstructures of the sintered parts were also examined. The solidified grains on the top sintered surface were observed; however, reasonable fusion was obtained at the interface between the baseline and the ceramics. Laser surface treatment using ZrO2 on magnesium alloy showed an improvement in corrosion resistance.

“…Pure yttria-zirconia powder was also sintered by a fiber laser with a wavelength of 1.064um. But the density and the mechanical properties of the produced samples can not meet the requirement for their potential medical application as dental bridges (Bertrand, 2007). Lower melting point constitutions, such as metal and organic powder were added into the ceramic powder to lower the sintering temperature and then form composite components.…”
