Lightweight, flexible, stiff, and hard, metal matrix composites have numerous applications. In addition to its high strength and corrosion resistance, aluminium 6061 has a wide range of mechanical properties as well as good working ability. In addition to Marine equipment, trucks, buses, and transmission towers, these products are used because of their high corrosion resistance. Friction stir welding is being employed in various fields like automobile, aeronautical, shipbuilding, and food industries due to its robustness. In FSW, The rotating tool generates heat by friction with the workpiece material, which results in a softened region near the tool. Through mechanical pressure applied by the tool, the hot and softened metal is then forged by the tool as it traverses along the joint line. Compared to fusion stir welded joints, friction stir welded joints are 34% stronger. Among the most common alloys that FSW can join are aluminium, copper, titanium, mild steel, stainless steel, and magnesium metals. The present work is focused on the problems such as rust development and corrosion of aluminium MMC in automobile, aircraft, and marine applications. The corrosion test of FSW Aluminium MMC plates can be done by the following methods Immersion test, Salt spray test, and electrochemical test. Our study intends to investigate corrosion behaviour on FSW Aluminium Metal Matrix Composite (MMC) by performing an Immersion test in Acidified Sea water solution. The immersion samples were 1 cm2 in size. The pH of the seawater used was 7.71 and by the use of a mixture of acids, the pH of the seawater was reduced to 2 in which they were immersed. The zones involved in this study are the Nugget zone (NZ), Thermo-mechanically affected zone (TMAZ) and Base metal zone.
