1. Vickers hardness is the hardness value expressed by the average pressure on the unit surface area of a square pyramid indentation.
2. Under the specified test force, press the diamond indenter with a square pyramid with an angle of 136° on the opposite side into the surface and maintain the specified
Time, then remove the test force. In this way, a square pyramidal indentation is pressed on the surface, and the average length of the two diagonals of the indentation is measured.
Calculate the indentation area to obtain the hardness value.
3. It can realize continuous hardness calibration of various materials from soft to hard. For example: widely used to test metal structures, including tiny
Parts, sheets, metal foils, wires, thin hardened layers and electroplated layers. It can also be used to test large tests such as glass, jewelry and ceramics
Materials that cannot be tested by force. It can also follow the structure of the metal to test the internal hardness of materials such as induction hardening or carburization.
2. Features
1. The test force is automatically loaded, maintained and unloaded.
2. Digital display calculation hardness value does not need to look up table conversion: input the indentation diameter and loading test force keyboard, and the display screen directly reads the hardness value.
