二、洛氏硬度计(一)洛氏硬度试验法洛氏硬度测量方法是 Rocwell 于1923年提出的。测定系在先后两次施加负荷(初负荷 P_0,总负荷 P)的作用下,将标准压头(金刚石圆锥或钢球)压入试样表面来进行。
Rockwell Hardness Tester Rockwell Hardness Test Rockwell hardness measurement method was proposed by Rocwell in 1923. The measuring system is to press the standard indenter (diamond cone or steel ball) into the surface of the sample under the action of twice the applied load (initial load P_0, total load P).
