Abstract
A plated product and apparatus for forming recesses or grooves on material to be plated to produce such a product. The product includes material having a surface having many recesses, each having an opening of size d, where d is in the range 5-100 microns, a depth in the range from 0.2 d to d, or many grooves. In preferred embodiments, each groove or recess has an anchor portion. In some embodiments, each groove has a ridge portion at each of both edges of its opening. The angle of each groove to the surface of the material and each groove's depth and opening width are preferably in specified ranges. When the material is plated, part of the thin metal film enters the anchor portions of its grooves or recesses, so that the plated metal has superior capacity to resist peeling off of the plated metal.
