Integrally Bladed Rotors (IBR), or Blisks, have become an important technology for the further development of the gas turbine engine. In order for blisks to be implemented in commercial flight a repair method for the aerofoils needs to be in place. This has led to the development of a number of potential repair methods, one of which is powder interlay bonding (PIB), which focuses on localised heating. This involves the incorporation of a small layer of alloyed powder in place between the two faying surfaces to be joined, acting as a catalyst to diffusion and reduces residual stresses after joining. This study involves the development of the PIB technique and the optimisation of a bond, in terms of porosity, using Ti 6246. A set of optimised bonding parameters were then characterised with the use of mechanical testing, including room temperature tensile testing and Vickers hardness testing.
