| Abstract Scope |
In this study, the influence of various surface modification techniques and scanning strategies on the mechanical performance of Ti6Al4V was investigated. The test pieces were fabricated using a layer thickness of 60 µm on a Renishaw’s 500Q multi-laser machine with one laser per part. Flat dog bone test pieces of varying thickness (1mm, 3mm and 5mm) were tensile tested and cylindrical test pieces of 6 mm diameter were tested under high cycle fatigue (HCF). All samples were heat treated and the only variable was the surface condition which varied between as-built, bead blasted and machined. The tensile testing results obtained from the as built and bead blasted specimens were lower than machined test pieces. This drop off in performance was more prominent in specimens with wall thickness < 3mm, highlighting the importance of selecting the appropriate scan strategies for the respective part geometry. |
