What is a Vickers hardness tester?
The Vickers hardness tester is a hardness tester that presses an indenter against the test material and judges the hardness based on the size of the surface area of the dent formed at that time. Similarly, the Brinell hardness tester is a hardness tester that determines hardness based on the size of the surface area. The Brinell hardness tester uses a 10 mm iron ball, while the Vickers hardness tester uses a diamond square pan with a facing angle of 136 °. To determine the surface area of the indentation on the test surface, the Vickers hardness tester measures the length of the diagonal line. Since the Brinell hardness meter is a spherical indenter, it measures the diameter.
Application of Vickers hardness tester
Vickers hardness is a test method that uses the value obtained by dividing the surface area of the indentation by the test load to determine the hardness. Since the facing angle of the indenter is fixed when calculating the surface area, the surface area is calculated by measuring the length of the diagonal line of the indentation. The lineup of test loads ranges from 10gf to 100kgf. A weight of 1 kg or less is called a Micro Vickers hardness tester. Basically, if the material is not uneven, the hardness value will not change even if the load is changed. As the notation of hardness, Hv is written after the test value, followed by the test load kgf. For example, if you get a result of 450Hv with a test load of 1kgf, it is written as 450Hv1.
