ABSTRACT:
A method of nondestructive testing of the surface of an object using vapor condensation, such as sputtering, evaporation, or gas disassociation, to lay a thin solid film upon the surface of the object to be tested. The film is either highly reflective or highly absorptive. Portions of the solid film are then removed from the surface, for example, by abrasion while the remaining coating material is in a pattern depending on anomalies. The surface is then irradiated and inspected under light and the differential reflection between the remaining coating material and the surface itself enhances the visibility of the crack or other surface characteristic. The technique is especially useful for detecting very small cracks in cutting or grinding implements made of compacted material.
