The Vickers Hardness Test entails utilizing a diamond indenter to apply force (also known as a “load”) to the test material in order to produce an indentation. The measurement of the specimen’s hardness is determined by the depth of the indentation in the material. Generally speaking, the harder the object is, the smaller the depression. Depending on the force used to indent the test material, hardness testing can be divided into micro-indentation tests and macro-indentation tests. (Micro-indentation tests normally employ loads up to 200 gf; macro-indentation tests typically employ loads up to 1000 gf.) The two most popular tests that can be used for both micro- and macro-indentation are the Vickers and Knoop hardness tests.

By pressing the diamond indenter into the surface being tested, the test is carried out. The indenter has a square base, a pyramidal shape, and opposite faces that are at an angle of 136 degrees with one another. Loads typically range from 1 to 100 kgf. Typically, the entire load is applied for 10 to 15 seconds.
