The surface treatment technology of copper forgings in construction machinery usually includes coating, spraying and anodizing. Here’s an assessment of these technologies and how effective they are:
- Coating: Copper forgings can be metal coating, such as nickel plating, chromium plating, etc. The coating can provide good corrosion resistance and decorative effect, make the forging surface more beautiful, and improve the load bearing capacity.
- Spraying: Construction machinery copper forgings commonly used spraying materials are polyether polyol (PU), polymer (PCT) and so on. The spray layer provides better corrosion protection against chemical corrosion and wear, while also increasing the wear and corrosion resistance of forgings.
- Anodizing: After anodizing copper forgings, a dense oxide layer can be formed. This oxide layer not only provides better corrosion resistance, but also enhances the hardness and wear resistance of the forgings. In addition, anodizing also has a ceramic texture, which can change the appearance of the forging color and improve its decoration.
For different construction machinery copper forgings, the choice of the appropriate surface treatment technology depends on the specific application needs and environmental conditions. Therefore, in practical applications, it is necessary to consider comprehensive factors such as the functional requirements of forgings, working environment and budget. At the same time, when selecting and evaluating surface treatment technology, it is also necessary to consider the cost, efficiency, construction technology and environmental friendliness involved.
