AA7075 is a candidate alloy which is extensively used in aerospace, defence and automobile applications due to its high strength, but key the problem associated with this alloy is low resistance towards corrosion. In this present investigation friction, stir processing technique was employed to modify the surface of AA7075 alloy. In the present work, AA7075-T6 plate is used as a substrate and is friction surfaced by a consumable rod (AA6061-T6) using a manual vertical milling machine. The microstructure of the surfaced region revealed the break-up and dispersion of coarse eutectics. It was observed that the corrosion resistance was improved when AA6061 is deposited on AA7075.
