Abstract
Laser metal deposition (LMD) is a metal additive manufacturing technique where in a metal component is built through layer-by-layer approach. Laser metal deposition is broadly used in fabrication and repairing of complex components for aerospace applications. The objective of this research paper is to focus on the bonding strength of Ti–6Al–4V alloy deposit fabricated under optimal process parameters and the substrate. Three-point bending test has been carried out on Ti–6Al–4V deposit and substrate shown that the bending strength of Ti–6Al–4V deposit is closer to the Ti–6Al–4V substrate. This result helps in restoration of complex aero engine parts with reduced lead-time and cost.
