"Pelorisation" is a term used in the field of metallurgy to describe a specific heat treatment process that enhances the properties and characteristics of metals. It involves subjecting a metal object or component to a combination of high heat and pressure in order to improve its durability, resistance to wear, and overall strength.
During the pelorisation process, the metal is first heated to a temperature below its melting point but above its recrystallization temperature. It is then placed under high pressure using specialized equipment such as hydraulic presses. The combination of heat and pressure promotes molecular rearrangement, which leads to the creation of a more uniform and refined microstructure within the metal.
This refinement of the metal's microstructure through pelorisation results in several beneficial outcomes. It enhances the material's hardness, making it less susceptible to scratches, dents, and other forms of surface damage. Additionally, pelorisation improves the metal's resistance to fatigue, allowing it to withstand repeated stress without deformation or failure. It also enhances the metal's resistance to corrosion, making it more suitable for applications in aggressive environments.
Pelorisation is commonly used in industries such as manufacturing, engineering, and construction where the strength and durability of metals are paramount. It is particularly effective in treating hardened steels, alloys, and other metal materials that require enhanced performance characteristics. Through pelorisation, these metals can be made more reliable, long-lasting, and capable of withstanding harsh operating conditions.
