Using the cone anvil made by self, inspect the hardness of small steel ball on WELSON - A653T Rockwell hardness tester ,solve the problem of the small steel ball is slip on the pedestal anvil and "V" shape anvil, difficult to fix,and make the variance analysis to the result compare with traditional method,and to prove the result , of inspect by this way is correct.
在WELSON—A653T洛氏硬度计上,采用自制凹锥形砧座测试微小钢球的硬度,解决了微小钢球在常用平面砧座和V形砧座上易打滑,不易固定,致使压头打在砧座上,损坏压头和砧座的难题,并采用方差分析的方法,将该法与传统试验方法相比较,验证其检测结果与传统法所获检验结果无显著性差异。

testing method for Rockwell superficial hardness
bi。)Tlian Luoshi Yingdu shi四nfo表面洛氏硬度试验法(testing meth记fo:Rock-wen supe币cialhi”diless)它的原理与洛氏硬度试验法相同，只是预负荷F0为29.4N，总负荷F为147N、294N、441N，深度差每1卿为一个表面洛氏硬度单位。它的标尺也有巧种，但常用的只有巧N、扔N、45N和巧T、30T、45T6种。前面的数字表示总负荷(以呵为单位的力值)，后面的N表示压头为金刚石圆锥体，T表示压头为直径1.588Inm的钢球。例如，刃闭解SN就表示用金刚石圆锥体在45呵(即44lN)总负荷时获得的表面洛氏硬度值为50。表面洛氏硬度试验方法适用于氮化、氛化、渗碳零件及薄试件表面硬度的测定。例如:巧N、3ON、45N标尺可用于硬质合金、氮化钢、渗碳钢、表面淬火钢、薄钢板、刀具及零件边缘部分和表面部分等，而巧T、30T、45T标尺可用于软钢、黄铜、青铜、铝合金等薄板。(施昌彦)
