style="text-indent:25px">電鍍鋅鎳合金的技術(shù)指標(biāo):1.鍍層鎳含量：鍍層耐蝕性與其鎳含量有著密切的關(guān)系。實(shí)驗(yàn)及有關(guān)資料均證明，鎳含量為13%左右的鋅鎳合金鍍層耐蝕性較好。因此，通常鋅鎳合金鎳含量控制在8～16%范圍內(nèi)，可滿足耐蝕性的要求。2.鍍層厚度：通常鍍層厚度在5～15μm即可滿足耐蝕性要求。對(duì)無(wú)公差要求的構(gòu)件，如護(hù)欄等，厚度可達(dá)20μm以上。3.鈍化膜質(zhì)量：鋅鎳合金經(jīng)鈍化處理后耐蝕性得到了提高。鈍化膜分為白色、黑色和五彩色三種，其耐蝕性順序?yàn)椋喊咨g化<黑色鈍化<五彩鈍化。4.鍍層結(jié)合力：根據(jù)GB5270多種方法檢測(cè)合格。5.耐蝕性：鎳含量為13%左右的鍍層經(jīng)五彩鈍化后，耐中性鹽霧實(shí)驗(yàn)2500小時(shí)以上不出現(xiàn)紅銹，預(yù)計(jì)耐大氣腐蝕15年以上。電鍍鋅鎳合金應(yīng)用范圍：可經(jīng)常應(yīng)用于汽車(chē)工業(yè)、緊固件工業(yè)、電纜橋架、高速公路護(hù)欄及海水環(huán)境中的鋼構(gòu)件等進(jìn)行防腐處理。南京電鍍鋅鎳合金什么價(jià)格鋅鎳合金鍍層具有的耐蝕性能、低氫脆性能、可焊可機(jī)械加工性能。</p><div

style="text-indent:25px">據(jù)知，我國(guó)酸性鍍鋅占電鍍鋅總量的50%以上，堿性鍍鋅約占40%左右，而酸性電鍍鋅鎳合金雖未見(jiàn)全國(guó)統(tǒng)計(jì)數(shù)據(jù)但據(jù)筆者估計(jì)不會(huì)超過(guò)10%。酸性鋅鎳合金電鍍所占比例如此之低的原因就在于大量本應(yīng)采用酸性鋅鎳合金電鍍的工件目前普遍采用了堿性鋅鎳合金電鍍工藝。僅據(jù)煤礦單體液壓支柱為例，全國(guó)使用量超過(guò)100萬(wàn)支，無(wú)數(shù)專(zhuān)一為此電鍍加工的單位普遍采用堿性鋅鎳合金電鍍工藝而不是酸性鋅鎳合金電鍍工藝。根據(jù)筆者對(duì)這兩種工藝的研發(fā)與生產(chǎn)實(shí)踐，這類(lèi)加工件在鍍層鎳含量相同、鍍層厚度相同、耐蝕性相似的情況下，采用酸性鋅鎳合金電鍍工藝其生產(chǎn)成本可降低50%左右，產(chǎn)量可提高2倍以上。鍍層經(jīng)變形加工后，仍具有優(yōu)于純鋅鍍層的耐蝕性。江蘇鋅鎳合金滾鍍廠</p><p

style="text-indent:25px">長(zhǎng)期以來(lái)，鋅及鋅合金主要用做防護(hù)性鍍層。金屬鋅防腐性能好，很大一部分用于金屬防腐的噴鍍、熱浸鍍和犧牲陽(yáng)極上。鋅合金摩擦系數(shù)小。鋅鋁阻尼合金能降低工業(yè)噪音和減輕機(jī)械振動(dòng)。鋅合金還具有超塑性和強(qiáng)度。因此鍍鋅工藝一直是國(guó)內(nèi)外長(zhǎng)期以來(lái)研究熱點(diǎn)。為進(jìn)一步提高其耐蝕性，人們提出了在傳統(tǒng)工藝的基礎(chǔ)上改善鍍層質(zhì)量的新技術(shù)，如鍍鋅、鋅鋁合金電鍍，鋅鎳合金電鍍，鋅鐵合金電鍍，鋅錳合金電鍍等。電鍍鋅也叫冷鍍鋅，是利用電解設(shè)備將工件經(jīng)過(guò)除油、酸洗后放入成分為鋅鹽的溶液中，并連接電解設(shè)備的負(fù)極；在工件的對(duì)面放置鋅板連接在電解設(shè)備的正極，接通電源，利用電流從正極向負(fù)極的定向移動(dòng)，就會(huì)在工件上沉積一層鋅。利用的是電解，在制作表面形成均勻、致密、結(jié)合良好的金屬或合金沉積層的過(guò)程。江蘇薄鍍層鍍鎳合金</p><p
