工作原理/ Working principle：

洛氏硬度的试验原理：用金刚石圆锥体压头或一定直径的钢球压头，在初试验力F0和主试验力F1先后作用下，压入试样表面，保持一定时间，卸除主试验力，保留初试验力，此时的压入深度为h1，在初试验力作用下的压入深度为h0，它们之差e(h1—h0)来表示压痕深度的永久增量。每压入0.002mm为一个洛氏硬度单位。（图1）

洛氏硬度的计算公式：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)
