Surface treatment is a process that improves the surface properties of metals through various methods. These include corrosion prevention, enhancing wear resistance, and improving aesthetic appearance. Unlike other processing techniques, surface treatment does not alter the shape or dimensions of a part; instead, it modifies its surface characteristics. While appropriate surface treatment can extend the service life of metal products, it also increases production costs.
Regarding the selection of metal materials, different materials possess distinct characteristics. For instance, steel exhibits high strength and hardness, making it suitable for applications involving heavy loads; aluminum and its alloys are lightweight and offer superior corrosion resistance, though their strength is relatively lower; and copper and its alloys possess excellent electrical conductivity, making them frequently utilized in electrical components. Selecting the appropriate material requires a comprehensive assessment of the operating environment, performance requirements, and cost considerations.
