電鍍處理工序的后處理種類(lèi)包括有除氫處理、鈍化保護(hù)處理。除氫處理對(duì)于電鍍后的產(chǎn)品來(lái)說(shuō)是很重要的，這是因?yàn)殄兘饘匐x子在陰極上得到電子，氫離子也同樣會(huì)得到電子，生成原子態(tài)的氫，滲透到金屬鍍層內(nèi)部，使鍍層產(chǎn)生疏松，當(dāng)放置一段時(shí)間后，原子態(tài)的氫會(huì)結(jié)合生成氫氣而體積膨脹，這樣就導(dǎo)致鍍層產(chǎn)生針眼孔、鼓泡甚至脫落等不良缺點(diǎn)。而所謂的鈍化處理則指的是在溶液中進(jìn)行化學(xué)或電化學(xué)處理，使得鍍層上形成一層堅(jiān)實(shí)致密的、穩(wěn)定性高的薄膜的表面處理方法，鈍化使鍍層的耐腐蝕性能進(jìn)一步的提高并增加表面光澤和抗污染的能力。合肥電子觸摸筆鍍銀目前無(wú)氰鍍銀的努力還主要是在尋求合適的電鍍工藝配方上。</p><div

鍍銀后是需要對(duì)銀層進(jìn)行一定的處理來(lái)防止其氧化變色的，下面介紹下一些常見(jiàn)的用來(lái)防止鍍銀層氧化變色的方法。使用硫|酸鹽鍍銀液鍍銀的在鍍膜后需要在干燥之前使用磷酸溶液進(jìn)行脫模處理，反復(fù)操作，脫模是為了防止日后發(fā)黃變色。鍍銀加工避免使用逆流漂洗，容易造成發(fā)霧現(xiàn)象。如果是銅基體鍍銀的話可以先預(yù)鍍一層銅，這樣既可以增加鍍層的結(jié)合力均勻性，有能阻止黃銅離子向銀層滲透。鍍銀后需要中和和鈍化處理，從而中和鍍銀過(guò)程中殘留的酸并且在鍍銀層身上形成一保護(hù)膜。鍍銀后要避免鍍膜后清洗不干凈，也要防止電流密度過(guò)高，再者就是要避免鍍液溫度過(guò)高。 </p><p style="text-indent:25px">鍍銀工藝相比起鍍銅、鍍鋅這些鍍種而言，其成本是要相對(duì)貴上少許的，因此鍍銀工藝中需要格外注意相關(guān)事項(xiàng)，防止材料的浪費(fèi)和成本的增加。鍍銀蕞基礎(chǔ)和重要的是要對(duì)基材進(jìn)行預(yù)處理工作，預(yù)處理做好了能增加基材與鍍層之間的絡(luò)合力。預(yù)處理總結(jié)起來(lái)就是要充分考慮基材表面結(jié)合力、導(dǎo)電性、平整度和殘留物的處理。鍍銀過(guò)程要注意添加劑的使用問(wèn)題，要及時(shí)給電解槽內(nèi)的各種添加劑進(jìn)行補(bǔ)充，防止電鍍失敗和其他問(wèn)題發(fā)生。另外在電鍍銀過(guò)程中要控制好電流水平以及持續(xù)時(shí)間，鍍銀快慢和厚度就是由此兩因素決定的。使表面處于活化狀態(tài)。也可以采用陰極電解的方法讓鎳表面活化，這樣可以進(jìn)一步提高鍍層的結(jié)合力。</p><div

材料表面化學(xué)處理中真空處理法，是指把在高真空狀態(tài)下使材料氣化或離子化沉積在加工件表面形成鍍膜層的過(guò)程，主要的方法有物***相沉積法、離子注入法和化學(xué)氣相沉積法。所謂的物***相沉積是指在真空條件下，把金屬氣化成原子或者離子等，然后直接沉積到工件的表面，形成涂層鍍膜的過(guò)程。所謂的離子注入則是在電壓下把不同離子注入工件表面令其表面改性的過(guò)程。所謂的化學(xué)氣相沉積則指的是低壓（或常壓）下，氣態(tài)物質(zhì)在工件表面因化學(xué)反應(yīng)而生成固態(tài)沉積層的過(guò)程。金屬銀粒對(duì)光敏感，因此是制作照相膠卷的重要原料。合肥電子觸摸筆鍍銀</p><p style="text-indent:25px">預(yù)鍍液一般分為兩類(lèi)，其標(biāo)準(zhǔn)的組成如下：鋼鐵等基材上的預(yù)鍍銀；銅基材上的預(yù)鍍銀。合肥電子觸摸筆鍍銀</p><p style="text-indent:25px">高壓局部鍍銀目前在許多工業(yè)生產(chǎn)中扮演中重要的角色，但是高壓局部鍍銀相比起普通鍍銀工藝需要更加專(zhuān)業(yè)的技術(shù)人員才能進(jìn)行，普通人員若是沒(méi)有經(jīng)過(guò)訓(xùn)練和實(shí)操是不建議操作的。部分零件局部鍍銀的常規(guī)處理方法通常是在不需要鍍銀的地方涂上保護(hù)漆和蠟，然后浸入鍍槽中對(duì)零件進(jìn)行局部拋光，鍍銀后再涂上保護(hù)層去除蠟件。可滿足手工鍍銀的要求，但由于保護(hù)漆層厚度大，往往難以去除保護(hù)部分，且保護(hù)效果太薄。另外，根據(jù)除漆除蠟的不同方法，在去除過(guò)程中，由于零件根部的去除或機(jī)械的去除，容易損壞零件的底座，特別是精密零件的局部鍍銀難以實(shí)現(xiàn)。合肥電子觸摸筆鍍銀</p><p
