Precision forged components refer to parts that are formed or deformed by heating metal billets, which have high strength, wear resistance, precision, and complex shapes. These parts are often used in mechanical equipment, automotive, aerospace, and medical equipment fields. Therefore, surface treatment is very important for them.
In China, policies and standards for surface treatment are constantly improving. Among them, “Environmental protection use identification of automotive industry products” (QC/T 681-2002) and “Guidelines for Energy-saving technology in the production process of automotive industry” (JT/T 693-2008) specify that environmentally friendly surface treatment processes must be adopted in the manufacturing of automotive components. Therefore, more and more manufacturers are beginning to replace traditional processes such as cadmium plating, which are serious environmental pollutants, with new technologies such as cyanide-free electroplating and chromate-free copper plating. These new technologies improve the surface quality and performance of parts while avoiding environmental impacts.
In practical production, different surface treatment methods can be used for different components. For example, acid pickling, phosphating, electroplating, anodizing and other methods can be used for high-strength forging parts to improve their corrosion resistance and surface hardness. For precision forged components, polishing, grinding, sandblasting, electrochemical polishing and other methods can be used for surface processing to improve their smoothness and accuracy.
In addition, in recent years, laser surface treatment technology has gradually been applied to precision forging component manufacturing. This technology can achieve precise control of the depth and shape of the part surface by controlling laser energy and scanning parameters, greatly improving the surface quality of the part. This technology is easy to operate, fast and produces good results. At present, laser surface treatment technology has been widely used abroad and is gradually being popularized in China.
In summary, it is very important to choose the appropriate surface treatment technology for different precision forging workpieces. Meanwhile, more environmentally friendly surface treatment processes will also be increasingly valued and promoted.
