skin friction/surface friction drag — Drag caused by the unevenness in the skin of a body. The layers of air near the surface are retarded, and the speed of the airflow increases as the distance from the skin increases. To reduce the skin friction, the surface should be smoothened to … Aviation dictionary
Friction stir welding — (FSW) is a solid state joining process (meaning the metal is not melted during the process) and is used for applications where the original metal characteristics must remain unchanged as far as possible. This process is primarily used on aluminum … Wikipedia
