DiamantEindringkörper

DiamantEindringkörper refers to a hardness testing indenter shaped from diamond. These indenters are a critical component in various hardness testing methods, most notably the Vickers and Rockwell hardness tests. The diamond's exceptional hardness, ranked at 10 on the Mohs scale, allows it to penetrate or impress upon a material without itself being significantly deformed. This ensures that the measurement of indentation size or depth accurately reflects the hardness of the tested material.

The geometry of the diamond indenter is precisely manufactured. For Vickers testing, it typically takes the form of a square-based pyramid with an angle of 136 degrees between opposite faces. In Rockwell testing, the indenter can be either a diamond cone with a tip angle of 120 degrees or a hardened steel ball of a specified diameter. The choice of indenter type and its precise dimensions are crucial for obtaining reliable and repeatable hardness measurements across a wide range of materials. The use of diamond is preferred due to its durability and its ability to create a clean, well-defined impression, which is essential for accurate measurement.
