工作原理/ Working principle：

洛氏硬度的試驗原理：用金剛石圓錐體壓頭或一定直徑的鋼球壓頭，在初試驗力F0和主試驗力F1先后作用下，壓入試樣表面，保持一定時間，卸除主試驗力，保留初試驗力，此時的壓入深度為h1，在初試驗力作用下的壓入深度為h0，它們之差e(h1—h0)來表示壓痕深度的永久增量。每壓入0.002mm為一個洛氏硬度單位。（圖1）

洛氏硬度的計算公式：HRA、C=100—(e/0.002)

HRB=130—(e/0.002)

The test principle of Rockwell hardness: Ball indenter or certain diameter diamond cone pressure head, in the initial test force F0 and the main test force under the action of F1 successively, pressed into the surface of the sample, keep a certain time, removable main test force, retain the initial test force, indentation depth of the H1, in the initial check depth of press force is H0, and the difference between them (e H1 H0) to represent the permanent incremental indentation depth. Each press 0.002mm as a Rockwell hardness unit. (Figure 1)

The calculation formula of Rockwell hardness:

HRA, C=100 (e/0.002)

HRB=130 (e/0.002)
