摘　　要：压头面积函数是影响纳米硬度测量的一个主要因素。本文对由于压头端部钝化对纳米硬度测量的影响进行了分析,并通过实验进行了验证。结果表明,面积函数校准对提高纳米硬度等材料力学性能参数的测量准确性十分必要。Area function is a main factor that affects the measurement of hardness by nanoindentation. The influence of tip rounding on measurement of nanohardness is analyzed and verified by experiments. It is shown that the calibration of area function of an indenter is very important for improving the measurement accuracy of nanohardness and other mechanical properties of materials by nanoindentation method.
