Investigation of The Surface Properties of Laser Surface Treated AISI 2205 Stainless Steel

27864

In this study, AISI 2205 duplex stainless steel surface properties of samples were investigated. Laser surface treatment was applied on the laser welded and non‐welded samples by means of Nd:YAG laser source at laser power 50W and 150W. The base metal and the weld seam surfaces of the laser welded samples on which untreated surface had been applied and the surfaces of the samples on which laser surface treated was applied were characterized via SEM‐EDS, atomic force microscope (AFM), and at the same time, the changes in their surface hardness were identified. As a results, it was identified that the base metal surface and the weld seam region of the laser welded sample on which untreated surface had been implemented had less roughness (Ra) than the samples on which laser surface modification had been applied. It was observed that the highest surface roughness belonged to the laser welded sample on which laser trated surface was applied via 150W laser power. No significant change was observed in the hardness values.
