Tempering Tempering is a heat treatment process commonly applied to metal materials to improve their mechanical properties, including hardness, strength, and toughness. In laser engraving, tempered metals exhibit enhanced resistance to wear and deformation, making them ideal for applications requiring durability and longevity.
During the tempering process, metal workpieces are heated to a specific temperature and then rapidly cooled to induce microstructural changes, such as the formation of fine-grained structures and precipitation of secondary phases. Laser engraving on tempered metals requires careful selection of laser parameters to avoid altering the material's microstructure or compromising its mechanical properties. |
