AlSi10Mg is widely used material in automobile, aerospace industries owing to good strength-to-weight ratio. Fabrication of AlSi10Mg using Laser Powder Bed Fusion (L-PBF) process allows to fabricate complex structures having high strength due to grain refinement. However, in the SLM process, the microstructure on the plane parallel (XY-plane) to the build direction is different from the plane perpendicular (XZ-plane) to the build direction. It results in different mechanical properties in different planes of the L-PBF product. So, in the present study, the tribological and corrosion tests are carried on the different planes of the AlSi10Mg samples. The wear volume, corrosion rate is studied and their surface morphologies are observed to understand the wear and corrosion mechanism.

摘要

AlSi10Mg is widely used material in automobile, aerospace industries owing to good strength-to-weight ratio. Fabrication of AlSi10Mg using Laser Powder Bed Fusion (L-PBF) process allows to fabricate complex structures having high strength due to grain refinement. However, in the SLM process, the microstructure on the plane parallel (XY-plane) to the build direction is different from the plane perpendicular (XZ-plane) to the build direction. It results in different mechanical properties in different planes of the L-PBF product. So, in the present study, the tribological and corrosion tests are carried on the different planes of the AlSi10Mg samples. The wear volume, corrosion rate is studied and their surface morphologies are observed to understand the wear and corrosion mechanism.
