    Microhardness



    Principle

    A constant force is applied on the sample surface with an indenter – typically a Vickers pyramid – in order to create a surface deformation. Then the hardness of the test sample is determined from the load needed to create the deformation and the dimensions of the permanent deformation.
    Hv = P/S

    Where P is the load applied on the sample surface (kgf)
    and S the indentation surface (mm²)

    Equipment

    Vickers STRUERS Duramin-1

    Microhardness tester is equipped with :

    - 9 types of loads, from 10g to 2 kg (eg HV0,01 to HV2)
    - Two objectives : X10 andX40

    Microhardness measurements are performed very quickly, with high accuracy and reliability, on all types of samples (metals, ceramics, compressed materials, integrated circuits, coatings,…). This equipment also allows observing grain microstructures.
