Universal nanomechanical testing machine Zwick ZHN

The test machine is used for indentation, scratch, wear and compression tests of materials and surface layers at room temperatures. The maximal loading capacity is 2N. The machine is equipped with diamond tips of Vickers, Berkovich type, spherical with diameters of 20 and 50 μm and flat tips with diameters 5 and 100 μm.

Three different types of holders allow fixing testing samples with sizes up to 50mm. The test machine is able to perform hardness tests with a slow, fast and ultrafast loading cycle. The elastic modulus can be measured according to ISO14577, by the QCSM method and by using a spherical tip. The testing machine further allows performing fatigue tests using spherical tip, scratch and wear tests.
