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.
