通過電解或化學(xué)方法在金屬或某些非金屬上鍍上一層鎳的方法，稱為鍍鎳。鍍鎳分電鍍鎳和化學(xué)鍍鎳。電鍍鎳是在由鎳鹽（稱主鹽）、導(dǎo)電鹽、pH緩沖劑、潤濕劑組成的電解液中，陽極用金屬鎳，陰極為鍍件，通以直流電，在陰極（鍍件）上沉積上一層均勻、致密的鎳鍍層。從加有光亮劑的鍍液中獲得的是亮鎳，而在沒有加入光亮劑的電解液中獲得的是暗鎳。 </p> <p> <br /> </p> <p> 化學(xué)鍍又稱為無電解鍍（Electroless plating），也可以稱為自催化電鍍（Autocatalytic plating）。具體過程是指：在一定條件下，水溶液中的金屬離子被還原劑還原，并且沉淀到固態(tài)基體表面上的過程。ASTM B374（ASTM，美國材料與試驗(yàn)協(xié)會(huì)）中定義為Autocatalytic plating is “deposition of a metallic coating by a controlled chemical reduction that is catalyzed by the metal or alloy being deposited”。這一過程與置換鍍不同，其鍍層是可以不斷增厚的，且施鍍金屬本身也具有催化能力，上海眾霖五金有限公司為上海眾新五金有限公司下屬子公司，主要從事各類金屬零件電鍍業(yè)務(wù)，其鍍種主要有：鍍鋅、鋅鎳合金，江蘇常熟市銅排鍍錫廠，江蘇常熟市銅排鍍錫廠、化學(xué)鍍鎳、電鍍鎳，江蘇常熟市銅排鍍錫廠、鍍金、鍍銀、鍍錫等。如您需要鍍錫業(yè)務(wù)，請聯(lián)系我們。

世紀(jì)的巴伐利亞，當(dāng)時(shí)的工人曾在鍛制的薄鐵板上進(jìn)行鍍錫。這種工藝后來傳至薩克森和波西米亞，至17 世紀(jì)，德累斯頓成為鍍錫板貿(mào)易中心。 </p> <p> 電鍍錫半球 </p> <p> 1720 年，英國南威爾士出現(xiàn)了熱鍍錫工廠，改用熱軋薄鐵板為基板，基板金屬及生產(chǎn)工藝的革新，使英國在19 世紀(jì)初確立了其作為世界主要鍍錫板生產(chǎn)國的地位。在隨后的發(fā)展中又出現(xiàn)了機(jī)械化的鍍錫機(jī)組，并以鋼代鐵作為基板。 </p> <p> 20 世紀(jì)30 年代，德國以前以商業(yè)性生產(chǎn)規(guī)模用冷軋帶鋼進(jìn)行電鍍錫。電鍍錫鍍層較薄，可以節(jié)約資源和成本。二戰(zhàn)期間，錫的供應(yīng)短缺促進(jìn)了電鍍錫工藝的發(fā)展。 </p> <p> 之后，連續(xù)電鍍錫取代熱鍍錫，在世界范圍內(nèi)被經(jīng)常采用。由于高速電鍍技術(shù)具有沉積速度快、產(chǎn)品質(zhì)量穩(wěn)定等優(yōu)點(diǎn)，在現(xiàn)代鍍錫板工業(yè)的發(fā)展中，高速電鍍錫技術(shù)日漸成熟，發(fā)展成為具有多種鍍液體系的高速電鍍技術(shù)。 </p> <p> <br /> </p><p style="text-indent:25px">鍍錫：是一種可焊性良好并具有一定耐蝕能力的涂層，電子元件、印制線路板中廣泛應(yīng)用。錫層的制備除熱浸、噴涂等物理法外，電鍍、浸鍍及化學(xué)鍍等方法因簡單易行已在工業(yè)上廣泛應(yīng)用。浸鍍是把工件浸入含有欲鍍出金屬鹽的溶液中，按化學(xué)置換原理在工件表面沉積出金屬鍍層。這與一般的化學(xué)鍍原理不同，因其鍍液中不含還原劑。與接觸鍍也不一樣，接觸鍍是把工件浸入欲鍍出金屬鹽溶液中時(shí)必須與一活潑金屬緊密連接，該活潑金屬為陽極進(jìn)入溶液放出電子，溶液中電位較高的金屬離子得到電子后沉積在工件表面。浸鍍錫只在鐵、銅、鋁及其各自的合金上進(jìn)行，上海眾霖五金有限公司為上海眾新五金有限公司下屬子公司，主要從事各類金屬零件電鍍業(yè)務(wù)，其鍍種主要有：鍍鋅、鋅鎳合金、化學(xué)鍍鎳、電鍍鎳、鍍金、鍍銀、鍍錫等。如您需要鍍錫業(yè)務(wù)，請聯(lián)系我們。如何鍍錫，請咨詢眾霖五金。</p><div

因?yàn)樵诠I(yè)大氣、海洋氣候或潮濕的大氣環(huán)境中很容易氧化發(fā)黑或產(chǎn)生銅綠，所以為了增加接觸面積，降低搭接面的接觸電阻，增強(qiáng)導(dǎo)電性而在銅排表面鍍錫。鍍錫層在空氣中有較好的穩(wěn)定性，兩種不同金屬材料之間在各種環(huán)境溫度中達(dá)到長久性的原子晶間結(jié)合，并且銅層鍍錫、鋅層分布均勻。硫酸鹽光亮鍍錫液成分簡單，主要有硫酸亞錫、硫酸、光亮添加劑、穩(wěn)定劑等成分。硫酸亞錫含量高時(shí)可用較大的電流密度，使沉積速度加快，含量過高會(huì)使鍍錫層粗糙。含量低時(shí)，允許的陰極電流密度降低，鍍層容易燒焦，對形狀簡單的零件可用硫酸亞錫含量低一些的鍍液。
