HARDNESS TESTING (HT)
Hardness is a characteristic of a material, not a fundamental physical property. It is defined as the resistance to indentation, and it is determined by measuring the permanent depth of the indentation.Hardness tests that measure the depth of indenter penetration include: Rockwell, Instrumented Indentation Testing, and Ball Indentation Hardness
Hardness tests that measure the size of the impression left by the indenter include: Vickers, Knoop, and Brinell
Before hardness testing of metallic materials or other materials, you must prepare the surface.
Advantages of HARDNESS TESTING (HT)
- It is the most rapid method and is fully automated.
- It has a rapid testing time.
- This test can be used for a wide range of materials.
