The diffusing hardening element in case of the carburizing process is-
Carbon
The fundamental principle behind carburizing is the diffusion of an element from a carbon-rich atmosphere or medium into the surface of the steel. Therefore, the primary element that diffuses into the steel surface during the carburizing process to enable subsequent hardening (via quenching) is carbon.
