Abstract
In this study, we compared the physical and chemical properties evaluation for each size in the SUS316L metal powder produced by water atomization and gas atomization. and we analyzed the experimental data in order to find the basis of a suitable metal powder (SUS316L) for DED (Direct Energy Deposition) processing. Also it evaluated the properties of each layered surface and cross section according to the number of deposition and deposition speed. In the result of optical microscopy measurements, the metal powder by water atomization was the crack generated between the deposition layer, the deposition layer was poor quality. However, metal powder by gas atomization was obtained a relatively good deposition results than metal powder by water atomization.
