陽極處理 (Anodizing )

陽極處理即是利用其容易氧化之特性，藉由電化學方法控制氧化層之生成，以防止鋁材進一步氧化，同時增加其表面的機械性，而氧化膜具有的耐腐蝕、耐磨耗、絕緣等特性，有效增加零件使用壽命，且可藉由陽極再生處理，大量降低零件報廢成本有效應用於光電、半導體工業等。

Anodizing is to take advantage of its easy-to-oxidize characteristics, to control the formation of the oxide layer by electrochemical methods to prevent further oxidation of aluminum materials, while increasing the mechanical properties of the surface, and the oxide film has corrosion resistance, abrasion resistance and  insulation characteristics, effectively increase the service life of parts, and can reduce the cost of scrap parts through anode regeneration treatment, and effectively apply to the optoelectronics  and semiconductor industries.

電解拋光(Electropolishing)

電解拋光是為了降低金屬表面的顯微粗糙程度，在一定電解液中進行金屬表面氧化膜的生成和溶解，使其表面粗糙度下降變平滑、且光亮度提高，並產生一定金屬光澤的技術；對於不銹鋼零件也可增加其耐蝕性，延緩銹斑與腐蝕的發生。

electropolishing is to reduce the micro-roughness of the metal surface, and generate and dissolve the metal surface oxide film in a certain electrolyte, so that the surface roughness is reduced and smoothed, and the brightness is improved, and a certain metallic luster is produced; For stainless steel parts, its corrosion resistance can also be increased to delay the occurrence of rust spots and corrosion.

不銹鋼鈍化處理(Stainless Passivation)

不銹鋼鈍化的方法，確保不銹鋼防蝕性能的流程，必須由兩步驟組成
1.清洗，這是最基本的一步，但有時候卻被忽略。
2.酸浸鈍化處理。
不銹鋼工件必須徹底清洗乾淨，將表面上可能殘存的油脂碎屑洗淨，使其具有優越的防蝕性能；但若不正確的鈍化也是有導致腐蝕的危機。
不銹鋼暴露於空氣或水分中，會自發性的形成具保護性的氧化膜，使其可隔絕腐蝕環境，增加耐蝕能力。

The method of passivation of stainless steel and the process to ensure the corrosion resistance of stainless steel must consist of two steps：

1. Cleaning, this is the most basic step, but sometimes it is ignored.
2. Acid leaching passivation treatment.

Stainless steel parts must be thoroughly cleaned, and the grease debris that may remain on the surface should be washed to make it have superior corrosion resistance; but if the passivation is not correct, there is a risk of corrosion.Stainless steel will spontaneously form a protective oxide film when exposed to air or moisture, which can isolate the corrosive environment and increase corrosion resistance.
