style="text-indent:25px">在鋁的基礎上進行鍍銀是行業(yè)內(nèi)比較常用的，鋁金屬本身具有良好的導電性能，傳熱效率快，比重輕，容易加工成形，但卻存在硬度較低，不耐磨，不易焊接的缺點。銀金屬則擁有良好的導電性（強于鋁金屬），并且有良好的額導熱性和焊接性能，化學性能穩(wěn)定，但是價錢偏高的缺點。在鋁的基礎上進行鍍銀就能很好的運用兩種金屬的特性，鍍銀鋁常應用在電器開關的接觸頭，用來防止銅氧化導電不良而引起的斷電跳閘現(xiàn)象；也應用在通信器上（雙工器，廣州筆記本外殼鍍銀、濾波器等），廣州筆記本外殼鍍銀，廣州筆記本外殼鍍銀，從而滿足電通要求，國內(nèi)的華為、中興等廠商的網(wǎng)絡通信器材就有使用到。因為當引入一些取代**物的化學品時，很難保證這些物質(zhì)對環(huán)境沒有新的污染；廣州筆記本外殼鍍銀</p><div

style="text-indent:25px">銀材料上電鍍白金也是近些年逐漸流行起來的一種電鍍工藝，電解鍍白金是采用正負電荷相吸的原理，在電介質(zhì)中帶電的貴金屬離子被異質(zhì)電荷的受體電場吸引并吸附在其上，在受體上形成貴|金屬涂層。純銀鍍白金基本上都是在裝飾行業(yè)中使用，因為純銀飾品在遇上空氣中的二氧化硫等含硫氣體或者含硫物質(zhì)，會發(fā)生反應而變黑。為了防止變黑和增加美觀度，所以在表面上要鍍白色金屬。電鍍不僅能使設備表面美觀，還能防止生銹、腐蝕，因此在生產(chǎn)實踐中得到諸多應用。另外，飾品行業(yè)選擇用純銀鍍白金這種方式加工銀飾品，也能使得產(chǎn)品價錢有更多的利潤空間。廣州手機攝像頭基座鍍銀廠商改善銀的性能和節(jié)約銀材，也開發(fā)了許多銀合金，如銀銅合金、銀鋅合金、銀鎳合金、銀鎘合金等。</p><div

對于絕大多數(shù)人而言都是不能有效的分辨純銀和鍍銀的區(qū)別，外觀上兩者基本上是同一種樣式，因此在裝飾品行業(yè)很多不良商家會使用鍍銀產(chǎn)品來坑騙消費者。鍍銀和純銀絕不是同一種產(chǎn)品，鍍銀只是單純的在基體表面上鍍上一銀層，其內(nèi)部可以是各種非銀物質(zhì)組成；而純銀產(chǎn)品則是因含量較為接近***銀的，鍍銀更多的是外在美，純銀更多的是內(nèi)在美。從飾品店購買回來的產(chǎn)品可以防止高溫焊搶下燒紅，待產(chǎn)品冷卻后若是出現(xiàn)黑色、暗黑色或發(fā)黃的情況，則是鍍銀產(chǎn)品或銀含量不高的產(chǎn)品。而純銀產(chǎn)品則會呈現(xiàn)如白紙一般的顏色。這個方法是蕞為簡單有效直接的方法，但是對于購買回來的產(chǎn)品很多消費者是不愿意這樣操作檢驗的。 </p><p> 材料表面化學處理中真空處理法，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程，主要的方法有物***相沉積法、離子注入法和化學氣相沉積法。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程。所謂的化學氣相沉積則指的是低壓（或常壓）下，氣態(tài)物質(zhì)在工件表面因化學反應而生成固態(tài)沉積層的過程。其他金屬如銅、等大多數(shù)金屬在鍍銀時，都會因銀的電位較正而在電鍍時發(fā)生置換反應，使鍍層結(jié)合力出現(xiàn)問題。</p><div
