MHVS-10V plus Vickers hardness tester

Unlike the traditional Vickers hardness tester, this Visual Vickers hardness tester cancels the use of traditional measuring eyepiece, projectes the Vickers indentation image to the operating screen, and can measure the indentation diagonal in the screen. The test process is faster and more intelligent to meet your requirement of high efficiency, convenience and precision hardness testing

Sample requirements
Although Vickers hardness can be used to measure both soft and hard materials, it also has its own requirements for specimens. Only by choosing the appropriate sample can the error be avoided and the accurate Vickers hardness value be obtained.

Sample appearance requirements
The surface of Vickers hardness specimen should be smooth and smooth, no oxide scale and impurities, no oil stain. Generally speaking, the surface roughness parameter Ra of Vickers hardness specimen is not more than 0.40μm, that of small load Vickers hardness specimen is not more than 0.20μm, and that of micro Vickers hardness specimen is not more than 0.10μm. (μm is the unit of surface roughness parameter Ra.)

Requirements for sample preparation
During the preparation of Vickers hardness specimen, the influence of superheat or cold hardening on surface hardness should be minimized.
In addition, for specimens with small cross-section or irregular shape, such as spherical or conical, it is necessary to mosaic the specimens or use special platforms.
