Abstract

For inspecting the structure of surfaces that are difficult to access, such as the walls of narrow drilled holes, without destroying the workpiece, silicon paste or a similar material is applied to the surface, cured, and removed. Then, the surface structure of the imprint can be microscopically inspected. When applied in drilled holes of a very small diameter, the cylinder with the hole imprint changes in the elastic range during removal but subsequently resumes its original shape which is representative of the wall structure and the dimension of the drilled hole.
