What is a Surface treatment / Heat treatment?

Surface treatment and heat treatment are processing techniques used to improve the properties of materials. These treatments are typically applied to metals and alloys to enhance their performance, such as increasing strength, durability, wear resistance, and corrosion resistance.

Surface treatment involves processes applied to the surface of a material, typically to improve its resistance to external factors. Common surface treatments include plating (electroplating a thin metal layer onto the surface), chemical treatment (using chemical reactions to improve surface properties), and hardening (heating the surface and quenching it to increase hardness).

Heat treatment is a process in which a material is heated to a high temperature and then cooled to alter its internal crystalline structure and physical properties. Examples of heat treatments include quenching (heating the material and rapidly cooling it to increase hardness), tempering (reheating the material after quenching to adjust hardness and toughness), and annealing (slow cooling after heating to relieve internal stresses). Heat treatment improves properties like strength, toughness, and ductility.

Both surface treatment and heat treatment are essential processes for improving product quality and ensuring optimal performance in various applications and environments.
