Abstract

The paper aims to analyze the effect of the specific parameters values and the surface preparation on the microhardness measurement accuracy. The various force and different time of penetration values has been applied in order to establish the measurement uncertainly in the case of a Bainitic steel sample. Also, the effect of the surface roughness and the scratching test behavior has been analyzed in order to study the superficial material characteristics.
