What is a Surface treatment / Heat treatment?

Surface treatment is a process that affects the exterior of an object and improves its performance and durability. This includes painting, plating, polishing, hardening, etc. Painting and plating contribute to corrosion prevention and improve appearance, and polishing improves surface smoothness. Surface treatments are selected depending on the material and tailored to the intended use of the product.

Heat treatment is a temperature-controlled process used to change the physical and mechanical properties of materials. Quenching improves hardness by heating and rapidly cooling the metal, while tempering reduces brittleness while maintaining a constant hardness. Heat treatment is applied to steel materials and alloys to improve their hardness, strength, and wear resistance, helping to improve the lifespan and performance of the material.
