Laser polishing of additive manufactured Ti6Al4V alloy: a review

Additive manufactured Ti6Al4V alloy has excellent comprehensive properties and broad application prospects in the aerospace, biomedicine, other fields. However, fabricated components are too rough to use directly. So, a corresponding postprocess is needed urgently. The conventional finishing process cannot meet requirements of green efficient processing because its time consumption, environmental pollution, low productivity. Laser polishing, as highly noncontact post-treatment technology, attracted more attention polishing additive alloy. research laser recent years expatiated includes mechanisms, surface roughness morphology, microstructure, mechanical properties, finite element simulation analysis during polishing. Furthermore, existing challenges laser-polished summarized, future development directions proposed.
