金屬製品在製造過程中，往往需要進行一系列的表面處理，以提高其耐腐蝕性、耐磨性和美觀度。其中，電鍍和酸洗是兩種常見的金屬表面處理技術。
電鍍是一種利用電化學原理，在金屬表面上鍍上一層金屬的方法。常見的電鍍包括鍍金、鍍銀、鍍鋅、鍍鎳、鍍鉻等，在不同的應用場合具有不同的效果。通過電鍍，可以使金屬製品表面更加光滑、耐磨、防腐蝕，同時還可以提高其導電性和導熱性。
另一種重要的金屬表面處理技術是酸洗。酸洗是通過浸泡金屬製品在酸性溶液中，去除表面氧化層和雜質，提高金屬表面的清潔度和光澤度。酸洗可以有效地去除金屬表面的氧化物，達到清潔和光亮的效果，為後續的表面處理工藝打好基礎。
金屬表面處理技術的選擇和應用，直接影響到金屬製品的質量和性能。通過適當的電鍍和酸洗處理，可以大大提高金屬製品的耐用性和美觀度，延長其使用壽命，滿足不同的應用需求。

Title: The Importance of Metal Surface Treatment Techniques
Article: During the manufacturing process, metal products often require a series of surface treatments to improve their corrosion resistance, wear resistance, and aesthetics. Among them, electroplating and acid cleaning are two common metal surface treatment techniques.
Electroplating is a method of depositing a metal layer on the surface of a metal using electrochemical principles. Common electroplating processes include gold plating, silver plating, zinc plating, nickel plating, chrome plating, etc., each with different effects in various applications. Through electroplating, the surface of metal products can be made smoother, more wear-resistant, corrosion-resistant, and can also improve their conductivity and heat conduction.
Another important metal surface treatment technique is acid cleaning. Acid cleaning involves immersing metal products in acidic solutions to remove surface oxide layers and impurities, improving the cleanliness and brightness of the metal surface. Acid cleaning can effectively remove metal surface oxides, achieving a clean and bright appearance, laying a solid foundation for subsequent surface treatment processes.
The choice and application of metal surface treatment techniques directly impact the quality and performance of metal products. Through proper electroplating and acid cleaning treatments, the durability and aesthetics of metal products can be greatly enhanced, prolonging their service life and meeting various application requirements.
