Processing And Corrosion Behavior Of Metal Powder Blends In LPBF

World PM2022 Proceedings, 2022
Laser Powder Bed Fusion (LPBF) has become an attractive alternative to conventional processing routes over the past years. While some alloys are already processed in series production, the overall amount of available materials is low. Due to the high price of specially atomized powders, material variation is often neglected.
