Mastering the Micro Vickers Hardness Tester Explained

14, Jul. 2026

 

Mastering the Micro Vickers Hardness Tester is essential for accurately measuring the hardness of small samples and thin coatings. This testing method is based on the Vickers hardness test, developed in the 1920s, which uses a diamond pyramid indenter to make an impression on the material being tested. The corner angle of the indenter is precisely 136 degrees, allowing for consistent measurements across a wide range of materials. The Micro Vickers Hardness Tester, with its lower scale of hardness measurement, is specifically designed for minute samples, making it highly valuable for industries relying on precision.

The Origin of the Micro Vickers Test

The origins of the Micro Vickers Hardness Tester trace back to the need for more precise methods of hardness measurement. While the traditional Vickers testing method provided a standard way to assess hardness, it was often inadequate for delicate materials or small components used in modern manufacturing. The introduction of the micro Vickers test addressed this limitation, allowing for testing on small and thin sections without compromising the material's integrity.

The Testing Process

In the Micro Vickers Hardness Test, a diamond pyramid-shaped indenter is pressed into the test material with a specific load, typically ranging from 10 to 1000 grams. The resultant impression's diagonals are measured under a microscope, which allows for precise calculation of the Vickers Hardness Number (HV). This number is derived from the applied load divided by the surface area of the impression, which is determined by the lengths of the diagonals. This method not only provides accurate hardness values but also enables testing of extremely small samples, enhancing its utility in research and manufacturing.
