Abstract:  
The method of inspecting shot peened surfaces of a workpiece for the extent of coverage comprises coating the surface to be peened of a workpiece with a material containing a fluorescent dye and then shot peening the part to be peened until the amount of fluorescent coating remaining, as indicated by the amount of fluorescent radiation given off when exposed to ultraviolet light, compares with the amount of fluorescent radiation given off from a previously prepared control specimen which has the same material characteristics as the workpiece and was coated with the same fluorescent material and shot peened to a desired coverage.
