Increasing the friction and wear performance of AISI 316L under dry, aqueous and oil lubricated sliding conditions with surface textures fabricated by laser-powder bed fusion (L-PBF)

In this study, it is aimed to examine the effects of surface textures on the friction and wear performance of materials under different sliding conditions (dry, aqueous and oil). AISI 316 L samples with hexagonal, circle, square and rhombus geometries were produced using Laser Powder Bed Fusion (L-PBF) and non-textured samples were produced using casting and L-PBF. L-PBF samples showed high peak intensity due to rapid heating- cooling and small shifts in Bragg angles occurred. L-PBF samples had higher hardness than casting samples since they had a finer microstructure. Textured samples exhibited better tribological performance because they trapped wear debris. A higher friction was observed in samples with sharp corners due to stress concentrations. The highest tribological performance occurred in oil-lubricated conditions.
