Investigation of Wear Behavior of Centrifugal Disc Finishing on Additively Manufactured Ti6Al4V Samples

As-built Additively Manufactured (AM) metallic parts require secondary processing in most applications to improve surface finish and mechanical strength. Mass Finishing (MF) processes are gaining popularity as effective and economical surface improvement methods for metal AM parts. This study investigates the wear behavior of post-processing both Laser Powder Bed Fusion (LPBF) and Electron Beam Melting (EBM) fabricated Ti6Al4V parts via Centrifugal Disc Finishing (CDF). Both AM orientation-based surface finish and wear behavior are compared for better understanding on key mechanisms of AM+MF hybrid manufacturing system. The areal surface roughness results showed that wear rate on side surfaces were higher than top surfaces for both LPBF and EBM samples in CDF. In addition, LPBF samples exhibited higher material removal than EBM samples based on weight loss measurements.
