Abstract:
The three different methods, the NRLM-type Vickers indenter verification instrument, the scanning white light interferometry and the atomic force microscope, are used for the wide-range verification of a Vickers indenter. Those methods are available in different range of indenter surface and it was found that the integration of different instruments are helpful for the better understanding of the thorough geometry of a Vickers indenter. In addition, an improved instrument is developed for low-force and microhardness range and evaluated its availability. The results show that it can indicate the similar value to the most reliable instrument even in the smaller range of indenter and it suggests that the range of the reliable verification may be expanded to low-force and microhardness.
