摘　　要：里氏硬度计是比较常用的硬度测试工具之一,通常都是采用里氏硬度块对其进行校准工作,但如果不具备里氏硬度块就需要另寻它法。文章通过采用比较常用的里氏硬度块、布氏硬度块和洛氏硬度块对3个比较常见的里氏硬度计进行校准工作,在保证里氏硬度块校准数据合格的情况下,通过分析其它硬度块校准数据,给出用标准布氏硬度块和标准洛氏硬度块校准里氏硬度计偏差较大的原因,并找出了相应的规律,最后对里氏硬度计的校准工作给出了一定的建议。Richter hardness tester is one of the commonly used hardness testing tools,usually using Richter hardness block for its calibration work,but if there is no Richter hardness block,we need to find another way.In this paper,three kinds of common Richter hardness testers are calibrated by using the Richter hardness block,Brinell hardness block and Rockwell hardness block,by analyzing the calibration data of other hardness blocks,this paper gives the reasons for the large deviation in calibrating the Richter hardness gauge with standard Brinell hardness blocks and standard Rockwell hardness blocks,and finds out the corresponding rules.Finally,some suggestions on the calibration of the Richter hardness tester are given.
