hardnessdepth
Hardness depth, also known as case depth, refers to the depth to which a material has been hardened by a surface treatment process. This hardening is typically achieved through methods like carburizing, nitriding, or induction hardening, which alter the microstructure of the material's surface layer. The depth of this hardened layer is a critical parameter that influences the component's performance and durability, particularly its resistance to wear, fatigue, and indentation.
The measurement of hardness depth is usually performed using a Vickers or Rockwell hardness test. A hardness
Factors influencing hardness depth include the type of surface hardening process used, the duration of the
