The Vickers and Knoop microhardness testing methods have become invaluable for the testing of a variety of parts, which have what can be referred to as “shallow layer hardness.” Such characteristics as surface hardness, thin cross section, coating hardness, and case depth are measured using the microhardness testing methods. These methods also can be useful for selective testing of particular grains or constituents such as those found in powdered metal parts.
