THE COMPARISON OF CALCULATED METHOD OF MATERIAL SURFACE NANO - AND MICROHARDNESS DEFINITION WITH OLIVER AND PHARR METHOD
Comparative tests of the hardness definition by the method which was offered in ISO 14577 and the KhNAHU technique in the range of nano- and microindentation were conducted. Monotonous character of the change of nano- and microhardness values in dependence on load which were calculated by the KhNAHU technique unlike zigzag character of the change of the curves which were plotted with the Oliver and Pharr method was established.
