  • kõvadus, mis mõõdetakse teemantpüramiidi katsetatavasse materjali sisse surumise teel
  • microindendatio hardness employing a 136o angle diamond pyramid indenter and variable load
Vickersi kõvadus
Usage examples
  • Vickersi kõvaduse tähistamise näide 440 HV30/20, kus 440 on kõvaduse number, HV kõvadusskaala Vickers tähis, 30 tähistab kasutatud koormust/massi kilogrammides ja 20 näitab koormamisaega, kui see erineb 10 s kuni 15 s.
Vickers hardness preferred
Usage examples
  • Vickers hardness numbers are reported as 440 HV30/20, where 440 is the hardness number, HV names the hardness scale Vickers, 30 indicates the load/mass used in kg, and 20 indicates the loading time if it differs from 10 s to 15 s.
