Surface Engineering of Steels: Understanding Carburizing

Surface Engineering of Steels: Understanding Carburizing

Carburizing is the addition of carbon to the surface of low carbon steels. It is generally accomplished at temperatures between 8501,000°C. Once quenched, the highcarbon surface layer yields a high hardness martensitic case with excellent wear and fatigue resistance [1]. This carburized case surrounds the tough, low carbon steel core.

The pack carburizing of dense parts from iron powder

1. When an active carburizer (charcoal mixed with barium or sodium carbonates) is used, the carburizing temperature of dense iron powder parts should not exceed 1223° K, as otherwise blister formation, swelling, and layering may take place on the surface of the parts. It is recommended that carburizing should be performed at ° K.
