Metal tool forgings have a wide range of applications in modern industry, including automotive, aviation, energy and other fields. Because these forgings often need to withstand complex working stress, so the research and application of surface treatment technology is particularly important. This paper will introduce the application and effect of surface treatment technology for metal tool forgings.
In the metal tool forging surface treatment technology, heat treatment, electroplating and spraying are the most common treatment methods.
Heat treatment is the method of heating and cooling to change the internal structure of a material, thereby improving its mechanical properties. In metal tool forgings, heat treatment can reduce the stress inside the metal and improve its hardness and corrosion resistance. For example, the quenching treatment of carbon steel can improve its hardness and wear resistance, while the solution treatment of stainless steel can improve its corrosion resistance and mechanical strength.
Electroplating is a technique in which a coating with special properties is added to the surface of a metal. In metal tool forgings, electroplating can increase its hardness, wear resistance and corrosion resistance. For example, plating a layer of hard chromium on the surface of a tool can make it more wear-resistant while also improving its resistance to corrosion.
Spraying is a technique for spraying paint evenly on a metal surface. In the metal tool forgings, spraying can form a protective film to improve its corrosion resistance and appearance quality. For example, spraying a coat of paint on the surface of a tool can make it more beautiful, while also preventing the erosion of moisture and oxide substances.
The application of different processing technologies can bring different effects on the performance and life of hardware tool forgings. Heat treatment can reduce the stress inside the metal and improve its fatigue resistance. Electroplating can increase its hardness, wear resistance and corrosion resistance, thereby improving its service life; Spraying can form a protective film to improve its corrosion resistance and appearance quality. Each of these processing technologies has advantages and disadvantages, so the selection should be balanced according to the specific application scenario.
In summary, the surface treatment technology of hardware tool forgings has an important impact on its performance and life. Heat treatment, electroplating and spraying are the most common treatment methods, each with its own unique advantages and disadvantages. When selecting a treatment method, it is necessary to choose the most appropriate surface treatment technology according to the specific application scenario and material of the forging. In the future, with the continuous emergence of new materials and new processes, we believe that the surface treatment technology of hardware tool forgings will be further improved and promoted.
