The Rockwell hardness tester only needs to touch the sample on one side to test the hardness of the metal. The Rockwell hardness tester is magnetically attached to the surface of the steel without supporting the sample. When we use the Rockwell hardness tester, there will inevitably be some problems

Micro hardness tester is often used to measure the hardness of individual phases in a material or very thin layers on a metal surface (e.g. plating, nitride layer). Its value can be expressed as Mohs hardness HM, Vickers hardness HV or Nuptial hardness HK. The specimen must be ground and polished to
