本文主要对文献所述“关于布氏硬度测深度法的分析”一文进行讨论。对用千分表测深法与用读数显微镜测压痕直径法的比较,对静态、动态测量以及数据分析和结论提出了不同的看法。在分析的基础上提出了布氏硬度较精确的计算公式。静态测量文献用了图1装置来测量压痕深度。虽然图中没有标出尺寸,但从千分表上推断,测量面底孔大于8毫米。因为,一般千分表顶杆的导套部分是8毫米,加之测量装置的千分表座中孔底部有倒角,
This article mainly discussed in the literature “on the Brinell hardness depth measurement method ” article is discussed. A comparison of the method of micrometer sounding with the method of measuring the indentation diameter with a reading microscope gives different opinions on the static and dynamic measurements and data analysis and conclusions. Based on the analysis, a more precise calculation formula of Brinell hardness is proposed. Static measurement literature using Figure 1 device to measure indentation depth. Although the figure does not indicate the size, but deduced from the dial gauge, measuring the bottom hole is greater than 8 mm. Because, in general, the guide part of the top gauge mandrel is 8 mm, together with the dial gauge measuring device at the bottom of the hole chamfer,
