The Mohs hardness test is one of the earliest attempts at defining and comparing the hardness of mineral materials. The Mohs scale consists of values from 1 to 10, which correlate with the ability of the test material to withstand scratching by progressively harder minerals. It is typically used for geological purposes.

You can measure the rebound or dynamic hardness of a material by dropping a diamond-tipped hammer on it. They then measure the hammer’s bound after striking the surface. If the hammer returns closer to the original dropping height, the material has a high value for rebound hardness. On the other hand, if the hammer didn’t get closer to the dropping height, the material has a low rebound

The Vickers hardness measurement principle is similar to Brinell hardness. A diamond quadrangular pyramid indenter with an opposite angle of 136 ° was used to press the surface of the material with a specified test force F. The test force is removed after holding for a specified time, and the hardness value is expressed by the average pressure on the unit surface area of the regular
