AN INVESTIGATION ON MECHANICAL PROPERTIES AND MICROSTRUCTURE OF Mg/Al ALLOYS USING Zn INTERLAYER DURING DIFFUSION BONDING

The general prerequisites of a part in the mechanical, automobile and aviation have given many testing conditions. New materials can be found and manufactured to some valuable segments. This work is directed to get a better understanding and portrayal of the dispersion holding of comparative and different metals. This work goes for building up a basic strategy to get diffusion bonding joints at generally not ease. In diffusion bonding, two metal surfaces are united into contact at expanded temperatures under strain for a specific timeframe. It also aimed to obtain optimum parameters for diffusion bonding of zinc coating over aluminium alloy plate and magnesium alloy. These two metals are jointed inside the die after finishing surface treatment. Then the die is kept inside the diffusion bonding machine by varying the time, temperature, pressure by means of load. Diffusion bonding equipment is fabricated and verified with experiments so that it is capable of rendering accurate diffusion bonding joints with facilities to measure parameters and to investigate the super plastic diffusion bonding joints with interlayer. This method is devised to study the mechanical and metallurgical characteristics of the joint.
