| Abstract: | One of the materials processing processes, currently in use by researchers and at an international industrial level, is Friction Stir Processing (FSP), an innovative solid-state processing process for the surfaces of metallic materials, developed from the friction stir welding process FSW. The FSP process is environmentally friendly and versatile, used for local processing, on welldefined areas, of the surfaces of metallic materials used in various applications. An interesting FSP processing method is the one in which the process takes place in a liquid working medium. Due to the water used as a working medium, the process temperature can be better controlled, avoiding excessive heating of the processing tool and the material to be processed, thus increasing the service life of the processing tool. Cast aluminum alloys are found in various industrial applications. The cast aluminum alloy EN AC 5083 has good mechanical properties, corrosion and chemical resistance, with applicability in the shipbuilding, aeronautics, automotive, chemical industries, etc. The paper presents results of experimental research carried out at ISIM Timi oara on friction stir processing in two different working mediums (underwater - SFSP and in ambient environment - FSP), in one pass and in multiple passes, of the cast aluminum alloy EN AC 5083 of 5 mm thickness. A comparison of the results obtained after evaluating the processed material by visual examination, with penetrating radiation, structural analysis, mechanical tensile and static bending tests is also presented, these being more favorable in underwater processing conditions.
