Carburizing is a critical surface hardening process widely used in high-performance bearing manufacturing. By diffusing carbon atoms into the surface of low-carbon alloy steel at elevated temperatures, carburizing creates a hardened martensitic case layer with hardness exceeding HRC 60, while maintaining a tough and ductile core (HRC 33–48). This unique combination significantly improves wear resistance,
