As a noble surface modification technique, friction stir processing (FSP) has been established based on the principle of friction stir welding that refines the microstructure and localized plastic deformation of the material. Nevertheless, despite notable technological progress, challenges persist in utilizing FSP to improve material characteristics. This review paper offers a concise overview, summarizing the influence of process parameters on the microstructure mechanical and tribological properties of aluminium alloy subjected to FSP. In particular, the performance of aluminium alloy is discussed about FSP factors such as tool travel speed, rotating speed, reinforcement particles, multiple passes and tool tilt angle. This paper also reviewed the effect of different process parameters on the wear properties, corrosion and tribological characteristics of the processed alloy, which will facilitate researchers and business organizations in creating the needed upgraded composite.
