The Vickers hardness (HV), is pressed into the sharp corners of the diamond test material, the size of the pits formed at this time to determine the hardness. Corresponding with the Brinell hardness of the ball indenter, and this test uses the pyramid indenter.
Due to the principle of Vickers hardness Brinell hardness, so these two cemented carbide tool hardness test values are very similar.
Cemented carbide tool hardness in the Rockwell hardness (HR) is the most commonly used machine shop. Especially after heat treatment, hardness test parts generally Rockwell hardness test. Rockwell hardness test method is widely used, its causes is the Rockwell hardness of the method is simple. Whether Brinell hardness, Vickers hardness, and the test method are required to measure the diameter or diagonal length of the pits indenter is very troublesome.
The rockwell hardness test method consists of indenting the test material with a diamond cone, hardened steel or tungsten carbide ball indenter.
