Why is it sometimes necessary to heat treat the surface and not the core? I.E. Why are surface hardening processes used? I tried to Google but to no avail. Thanks.

Surface hardening is a process used to increase the hardness and durability of a material's surface. This is achieved by altering the surface layer of the material through various techniques, such as heating, cooling, or adding a coating.
Some common types of surface hardening processes include case hardening, carburizing, nitriding, induction hardening, and flame hardening. Each process uses different techniques to alter the surface properties of a material.
Almost any material can be surface hardened, including metals, plastics, and ceramics. However, the most common materials that undergo surface hardening are steel, aluminum, and titanium.
The main benefit of surface hardening is increased surface hardness and durability, which can improve the wear resistance, strength, and longevity of a material. It can also improve resistance to corrosion and other forms of damage.
The choice of surface hardening process depends on various factors, such as the type of material, desired surface properties, production time and cost, and the size and geometry of the part. It is important to consult with a materials expert to determine the best process for a specific application.
