Abstract
Fluid jet polishing (FJP) is a method of contouring and polishing a surface of a component by aiming a jet of a slurry of working fluid from a nozzle at the component and eroding the surface to create a desired shape. During erosion, the end of the nozzle and the component are submerged within the working fluid, whereby air is not introduced into the closed loop of working fluid slurry. Any bubbles that are present in the system simply bubble to an air pocket at the top of the erosion chamber and are not re-circulated, thereby producing surfaces with very smooth surface finishes.
