Abstract:
Vickers hardness is widely used in the performance testing of the metallic medical devices. It discusses the relationship between different test force and the uncertainty by mathematical simulation and experiment. With the increase of test force its uncertainty becomes smaller at 400 times magnification. If you can, you should try to choose a large test force, in order to improve the accuracy and repeatability. In the actual testing process, it is best not to use the micro vickers hardness test.
