The Vickers hardness measurement scale
The Vickers hardness measurement scale – is the hardness tester scale for hardness testing by the Vickers method. The essence of the method consists in pressing a regular tetrahedral diamond pyramid with an angle of 136 ° between opposite faces into the test material.Vickers hardness is calculated by dividing the load P by the surface area of the resulting pyramidal imprint. The Vickers method determines the hardness of nitride and cement surfaces, as well as thin sheet materials.
