- Abstract:
- The current paper describes the results of measurements conducted during the improvement of the national primary hardness standard machine on Vickers scales. As a result of improvement, the range of applied loads has been expanded from 0,098 N to 0,0098 N. This helped to provide the uniformity of hardness measurements on Vickers scales HV0,005, HV0,002 and HV0,001, expand the standard machine application area as well as reduce measurements uncertainty on the primary standard machine as a result of studying geometrical parameters of reference indenters with the help of a new high-precision complex. A base for the development of a new national hardness standard machine in the field of nanoindentation at the loads of less than 0, 0098 N has been created.
