style="text-indent:25px">鍍銀工藝流程總結(jié)起來包括除油、拋光、鈍化、酸活化、預(yù)鍍銀、銀保護和水洗這幾個流程。除油可以簡單的理解為出去油污，除油的方式包括有高溫除油、滾桶出游、電解除油和聯(lián)合方式除油。拋光則是進一步去除零件表面的氧化層油污層為工件提供一個完整的膜層。鈍化則是處理拋光工序后殘留在零件表面上的殘渣。酸活化則是處理鈍化工藝的膜層，使得零件的表面活性和鍍層更加具有結(jié)合力。預(yù)鍍銀工序則是為了讓那個加工件的表面形成銅銀絡(luò)合物，增加加工件和鍍層的結(jié)合力并具有防變色功能。銀保護工序則是讓鍍層表面在形成以銀絡(luò)合物保護膜防止銀鍍層氧化變黑。水洗則是為了清洗各工序殘留的溶劑污漬。</p><div

鋁材鍍銀液屬于鋁材表面處理中的一種，鋁材表面化學(xué)轉(zhuǎn)化處理能為鋁材表面提供多種多樣的保護，通常采用的方法有陽極氧化法、復(fù)合氧化法、稀土轉(zhuǎn)化膜法、微弧氧化法、有機硅烷化處理等等。以其中的陽極氧化法和化學(xué)氧化法為例，鋁材使用陽極氧化法是將鋁材作為陽極，讓入***等電解液中，施加陽極電壓進行電解,讓鋁的表面形成一層致密的三氧化二鋁膜,此膜是由致密的阻礙層和柱狀結(jié)構(gòu)的多孔層組成的雙層結(jié)構(gòu)。鋁才化學(xué)氧化法是在相關(guān)的溫度條件下，借助化學(xué)反應(yīng)在加工件表面形成一層氧化膜的方法。
