1、電鍍分為:鍍鋅(彩鋅,白鋅,藍鋅,黑鋅),鍍鎳,鍍鉻等; 主要是在料件表面形成一層防護層,起保護及裝飾的作用;

1. Electroplating is divided into: galvanizing (color zinc, white zinc, blue zinc, black zinc), nickel plating, chrome plating, etc; The main function is to form a protective layer on the surface of the material, which plays a protective and decorative role;

2、噴涂分噴漆及噴粉兩種,是將料件經過前處理以后,用噴槍,氣體把涂料噴到鈑金工件表面上,涂料在工件表面形成涂層.烘干后,起防護的作用;

2. Spray painting can be divided into two types: spray painting and powder spraying. After pre-treatment of the material, the coating is sprayed onto the surface of the sheet metal workpiece with a spray gun and gas, forming a coating on the surface of the workpiece After drying, it has a protective effect;

3、其它的表處方式:陽出彩氧化,鉻酸鹽,拉絲,噴砂,氧化等;

3. Other surface treatment methods: anodizing, chromate, wire drawing, sandblasting, oxidation, etc;

注意事項!

matters needing attention!

1. 所有電化學處理都應在零件狀態下進行，因為處理過程中的化學溶液會被截留在組合件的縫隙之中而引起腐蝕;

1. All electrochemical treatments should be carried out in the state of the parts, as the chemical solution during the treatment process can be trapped in the gaps of the assembly and cause corrosion;

2. 點焊的零件可進行化學處理，但不能進行電化學處理(包括電鍍、陽出彩化);

2. Spot welded parts can undergo chemical treatment, but cannot undergo electrochemical treatment (including electroplating and anodizing);

3. 鋁合金鑄件不能進行硫酸陽出彩氧化處理;

3. Aluminum alloy castings cannot undergo sulfuric acid anodizing treatment;

4. 細而長的管形(其長度大于2倍直徑)零件一般不宜進行電化學處理，因為其內表面將沒有膜層;(特殊情況可采取非常措施來滿足要求)

4. Thin and long tubular parts (with a length greater than twice the diameter) are generally not suitable for electrochemical treatment because their inner surface will not have a film layer; (Special measures can be taken to meet the requirements in special circumstances)

5. 有較深凹槽或細孔(一般指深度大于2倍直徑或開口寬度，但優良的工藝可不受此限)的零件電鍍后，其內表面將不能完全覆蓋鍍層;

5. Parts with deep grooves or pores (generally referring to depths greater than twice the diameter or opening width, but excellent processes may not be limited to this) will not be able to fully cover the coating on their inner surface after electroplating;
