Abstract Scope |
In the aero engine components such as gas/jet turbine parts, Ti alloys are widely incorporated except some parts which are made by nickel base super alloys. Joining Ti components one with the other can be achieved by diffusion bonding technique. In this investigation, thin sheet of Ti6Al4V alloy which is having a thickness of 2 mm are diffusion bonded with the aim of analyzing the sensitivity of each process parameter on the bonding characteristics. Using response surface methodology (RSM), empirical relationships were established to predict the Ti6Al4V bond characteristics. Three factor 3 level central composite design matrix consists of 15 runs was obtained from Design Experts software. The responses such as shear strength, bonding strength and hardness were evaluated, analyzed numerically and graphically. From the sensitivity analysis, bonding temperature is found to be more influencing factor followed by bonding pressure and holding time.
