在金相显微镜下,用几种方法测量不同钢材、不同形貌的硼化层厚度,并将测量的数据进行统计处理。根据“等效体积”的思想,用图象分析仪测出硼化层的面积,求出了等效厚度。测量数据的计算结果证明等距平均值与等效厚度很接近,硼齿峰谷平均值与等效厚度也很接近,因此可用等距平均值或峰谷平均值代表等效硼化层厚度。又从统计观点出发,硼化层的厚度需根据20个点的测量值来确定。
In the metallographic microscope, several methods were used to measure the thickness of the boride layer of different steel and different shapes, and the measured data were statistically processed. According to the idea of “equivalent volume”, the area of boride layer was measured by image analyzer, and the equivalent thickness was obtained. The calculation results of the measured data prove that the equidistant average value is close to the equivalent thickness, and the average value of the boron tooth peak valleys is also close to the equivalent thickness. Therefore, the equidistant average value or the average of the peak valleys can be used to represent the equivalent boronized layer thickness. Again from the statistical point of view, the thickness of the boride layer should be based on the measured value of 20 points to determine.
