Bicycles are often exposed to the outdoor environment as a means of transportation, the surface treatment of its forgings is very important to improve the corrosion resistance and beauty. By using appropriate surface treatment technology, the service life of forgings can be effectively extended, while improving the appearance quality of bicycles. This article will introduce several common surface treatment techniques for bicycle forgings, including galvanizing, anodizing, and spraying.
First of all, galvanizing is a common surface treatment technology. By dipping the forgings into the molten zinc solution, a uniform layer of zinc alloy is formed to cover the surface of the forgings, thus achieving anti-corrosion protection of the forgings. Zinc has good corrosion resistance, can effectively resist the erosion of water, oxygen and acid and alkali substances, delay the oxidation and corrosion rate of forgings. In addition, the galvanized layer can also provide a certain wear resistance, scratch resistance, enhance the service life of the forging. At the same time, the galvanized layer is silver white, which can improve the beauty of the bicycle.
Secondly, anodizing is a common surface treatment technology for aluminum alloy bicycle forgings. In the anodic oxidation process, the forgings are soaked in an electrolyte containing oxidants, and direct current is applied to form a dense and uniform oxide film on the surface of the forgings. The oxide film has good corrosion resistance and hardness, which can effectively prevent oxidation, corrosion and scratches. In addition, the oxide film also has certain adsorption properties, which can be used for dyeing treatment to increase the appearance of the bicycle. Anodizing technology is not only suitable for aluminum alloy forgings, but also can be applied to the surface treatment of other metal materials.
In addition, spraying technology is also a common surface treatment method for bicycle forgings. By spraying a specific color of paint on the surface of the forgings to form a uniform coating, corrosion protection and aesthetic improvement of the forgings are achieved. Spraying technology can choose different kinds of coatings, such as epoxy resin, polyester powder, etc., according to the need for color and effect selection. In addition, the spray coating can also provide certain wear resistance and scratch resistance, extending the service life of the forging.
In summary, the surface treatment technology of bicycle forgings is crucial to improve corrosion resistance and aesthetics. Galvanizing, anodizing and spraying are common surface treatment methods for bicycle forgings, which achieve anti-corrosion protection and appearance improvement of forgings by forming a covering layer or coating on the surface of the forgings, respectively. When choosing a bicycle, in addition to paying attention to the quality of core components such as frames and wheels, riders should also pay attention to the surface treatment of forgings to ensure the safety and beauty of the bicycle.
