carburizing
Steel surface hardening
Carburizing is a heat treatment process that hardens the surface of steel by infusing it with carbon.
The metal is heated in a carbon-rich environment—historically charcoal, now often gas—allowing carbon atoms to diffuse into the surface layer.
The result is a hard, wear-resistant exterior while the core remains tough and ductile: The gears were carburized to prevent surface wear.
Also spelled carburising in British English.
