The Vickers hardness test uses a diamond pyramid in the shape of a square pyramid with an angle of 136 ° between opposite sides. The Vickers hardness is expressed as a quotient obtained by dividing the test load of the indenter by the surface area determined by the diagonal length of the depth.
Regardless of the size of the test load, the Vickers hardness tester provides consistent results for homogeneous materials. These characteristics are unique to the Vickers hardness test.
The Vickers hardness test method can also be used to continuously test the hardness of materials, from soft to hard, using the same measuring scale.
Vickers and micro Vickers hardness testers can use both Vickers and Knoop indenters.
