technological innovation
Heat treatment: By precisely controlling the heating and cooling processes, the microstructure of the tungsten rod is changed, thereby improving its strength and hardness.
Deformation strengthening: Using cold processing (such as cold rolling, cold drawing) or hot processing (such as forging, extrusion) methods to cause plastic deformation of tungsten rods, thereby enhancing their mechanical properties.
Composite strengthening: Combining tungsten with other metallic or non-metallic elements to form composite materials, utilizing synergistic effects to enhance overall performance.
Result: After strengthening treatment, the key indicators such as tensile strength, yield strength, and hardness of tungsten rods have been significantly improved.
3. Surface treatment technology
Background: Tungsten rods are susceptible to corrosion due to environmental factors during use, therefore surface treatment technology is crucial.
technological innovation
Coating technology: Apply a corrosion-resistant coating (such as ceramic coating, metal coating, etc.) on the surface of the tungsten rod to effectively isolate the external medium from direct contact with the tungsten rod, thereby delaying the corrosion process.
Anodizing: By electrochemical methods, a dense oxide film is formed on the surface of tungsten rods to improve their corrosion resistance.
Ion implantation: Using ion implantation technology to inject corrosion-resistant elements (such as chromium, nickel, etc.) into the surface of tungsten rods, forming a stable compound layer to enhance their corrosion resistance.
Result: After surface treatment, the corrosion resistance of tungsten rods has been significantly improved, and they can maintain long-term stable working conditions in harsh environments.
4. Expansion of application areas
