Rockwell Hardness Test
The Rockwell hardness test involves a mechanical operation where an indentation tool made of diamond is placed against the test subject. Then, a preliminary force is applied, and the indentation depth is measured. Next, the total force load is added, with the indentation depth measured again. The total force load is then removed, so only the preliminary force remains in action. The difference between penetration depth before and after the total force is applied is then used to calculate the Rockwell hardness number. The Rockwell Hardness number is calculated by the equation:
100 – (H/0.002) = Rockwell Hardness number ; Where H = the depth of indentation in mm.
