  2. Case-hardening - Wikipedia

    en.wikipedia.org/wiki/Case-hardening

    This causes carbon to diffuse into the surface of the steel. The depth of this high carbon layer depends on the exposure time, but 0.5mm is a typical case depth. Once this has been done the steel must be heated and quenched to harden this higher carbon 'skin'. Below this skin, the steel core will remain soft due to its low carbon content.

  7. Rockwell hardness test - Wikipedia

    en.wikipedia.org/wiki/Rockwell_hardness_test

    The depth of penetration from the zero datum is measured, on which a harder material gives a lower measure. That is, the penetration depth and hardness are inversely proportional. The Rockwell test does not use any optical equipment to measure the hardness indention, rather all calculations are done within the machine to measure the indention ...
