DIFFERENCE BETWEEN SURFACE AND CORE TEMPERING

Question

Accepted Answer

Surface tempering and core tempering are heat treatment processes used to improve the properties of materials.

Surface tempering involves heating the surface of a material to a specific temperature and then cooling it rapidly to increase its hardness and wear resistance.
Core tempering, on the other hand, involves heating the entire material to a specific temperature and then cooling it slowly to improve its toughness and reduce brittleness.
Surface tempering is commonly used for tools and components that require high hardness, such as drill bits and cutting blades.
Core tempering is often used for materials that need to be both strong and tough, such as structural steel or automotive parts.
Both surface and core tempering are important processes in the field of metallurgy to enhance the mechanical properties of materials.
