  • materjali kõvadust iseloomustav näitaja, mis on määratud Vickersi meetodil (vrd Rockwelli kõvadusarv, Brinell kõvadusarv)
  • a number related to the applied load and surface area of the permanent impression made by square-based pyramidal diamond indenter (compare: Rockwell hardness number, Brinell hardness number)

VHN
  • Vickersi katsega saadud kõvadusväärtus
  • unit of hardness given by the test is known as the Vickers Number (HV)
Vickersi kõvadusarv
Usage examples
  • Vickersi kõvadusarvu saab teisendada paskalitesse, kuid seda ei tohiks segi ajada rõhuga, mis kasutab samu ühikuid, kuna kõvadusarv mõõdetakse koormusega süvendi pindalal, mitte jõu suhtes normaalsel alal, ning seetõttu ei ole see rõhk.
Vickers hardness number preferred
Usage examples
  • The Vickers hardness number can be converted into units of pascals, but should not be confused with pressure, which uses the same units. The hardness number is determined by the load over the surface area of the indentation and not the area normal to the force, and is therefore not pressure.
