Brinell hardness of diamond

WebUnlike Brinell’s and Vickers’s methods, Rockwell’s method does not measured the size of the imprint, but the depth of penetration of the indenter. That is why in case of Rockwell the hardness is read on the … Web√ Brinell Hardness Test. This test is one of the most widely accepted hardness tests used by a machinist. Here a ball of 10mm is used as an indenter to make an impression on the material to help calculate its Brinell hardness value. The ball is held in place for a few seconds, usually 30 seconds, while a force is applied.
