The ball screw actuator of the airplane is subjected to wear which can greatly affect flight conditions. Different materials were used for testing, subjected to different efficient coatings, while the second technique was by means of lubrication. Finally, the techniques were contrasted to determine whether the first, second or both lead to the highest efficiency, with the aim being a longer lifespan and perhaps a better operational cost. A finite element analysis has been made on different balls of different materials while coated and uncoated. After inspecting the results of the relevant studies in the literature, several conclusions were arrived to that would help reduce wear, such as an optimized return path, better choice of material, better coating, and appropriate lubricant.
