style="text-indent:25px">電鍍鋅鎳合金具有一下優(yōu)勢：1.優(yōu)異的耐腐蝕性。同樣厚度時，鋅鎳合金層耐腐蝕性為純鋅鍍層的4-8倍，鍍層本身對鋼鐵基體為陽極性鍍層，可提供有效的陰極保護(hù)作用。2.厚度保持在螺紋公差范圍內(nèi)5～15μm的厚度，可獲得較長時間的耐蝕性。顯示涂層本身具有非常低的腐蝕速率。3.鍍層與基體間有足夠的結(jié)合力，以保證鍍層發(fā)揮其高耐蝕性。4.優(yōu)良的耐熱疲勞性能。在-60-250℃之間鍍層經(jīng)激冷激熱處理后，表面處理鋅鎳合金生產(chǎn)供應(yīng)，其耐蝕性無變化。5.可加工性與電鍍純鋅層相當(dāng)。鍍層經(jīng)變形加工后，仍具有優(yōu)于純鋅鍍層的耐蝕性。6.低氫脆性。鋅鎳合金鍍層氫脆率*為1.5%，而電鍍純鋅的脆化率一般均在40%以上，光亮鍍鎘層為18%左右。7，表面處理鋅鎳合金生產(chǎn)供應(yīng).鋅鎳合金鍍層的硬度比純鋅高，表面處理鋅鎳合金生產(chǎn)供應(yīng)，因而具有更好的耐磨性。8.工藝操作簡便。電鍍鋅鎳合金的工藝流程及設(shè)備與電鍍純鋅一樣，不需增加特殊的裝備。電鍍鋅鎳合金溶液的維護(hù)一般每周都需要對鍍液進(jìn)行分析并進(jìn)行調(diào)整。表面處理鋅鎳合金生產(chǎn)供應(yīng)</p><div

style="text-indent:25px">我國酸性鍍鋅占電鍍鋅總量的50%以上，堿性鍍鋅約占40%左右，而酸性鋅鎳合金電鍍雖未見全國統(tǒng)計(jì)數(shù)據(jù)但據(jù)筆者估計(jì)不會超過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。*據(jù)煤礦單體液壓支柱為例，全國使用量超過100萬支，無數(shù)專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)筆者對這兩種工藝的研發(fā)與生產(chǎn)實(shí)踐，這類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。南京金屬鍍鋅制造商鈍化之后的鋅鎳合金鍍層的耐蝕性要比鋅鍍層高出多倍。</p><div

style="text-indent:25px">無氰鍍鋅又分為兩大類：弱酸性鍍鋅與堿性鍍鋅；弱酸性鍍鋅又分為硫酸鹽鍍鋅與氯化物鍍鋅，堿性鍍鋅又分為鋅酸鹽鍍鋅和焦磷酸鹽鍍鋅；而應(yīng)用普遍的是鋅酸鹽鍍鋅，氯化物鍍鋅也有一定的應(yīng)用。鋅鎳合金電鍍是在無氰鍍鋅的基礎(chǔ)上發(fā)展起來的，目前鋅鎳合金分為兩個體系：弱酸性體系和堿性體系。氯化鉀鋅鎳合金鍍液是由氯化鉀鍍鋅演變而來，其優(yōu)點(diǎn)是電流效率高，通?？蛇_(dá)到95%以上，沉積速度快，對鋼鐵基體氫脆小，污水處理簡單，容易得到高鎳含量的合金鍍層，其缺點(diǎn)是鍍液的分散能力及覆蓋能力不好，氯離子對設(shè)備腐蝕性大，鍍層含鎳量高于15%時，鈍化困難，膜有缺陷，耐蝕性差，含鎳量低于9%時，耐蝕性也差，含鎳量在13%左右，耐蝕性好。</p><p style="text-indent:25px">鍍鋅鎳合金，隨著工業(yè)技術(shù)的發(fā)展，對防腐技術(shù)的要求越來越高。尤其在惡劣環(huán)境中，以往常規(guī)的防腐手段，如發(fā)藍(lán)、鍍鋅、浸鋅等已不能滿足緊固件等鋼鐵構(gòu)件的長效防腐要求。鍍鋅鎳合金層技術(shù)具有高耐蝕、薄鍍層、低氫脆、可加工、易操作等特點(diǎn)。可普遍應(yīng)用于汽車工業(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)件等的防腐處理。鍍鋅鎳合金有優(yōu)異的耐腐蝕性。同樣厚度時，鋅鎳合金層耐腐蝕性為純鋅鍍層的4～8倍，鍍層本身對鋼鐵基體為陽極性鍍層，可提供有效的陰極保護(hù)作用。電鍍工藝過程：一般包括電鍍前預(yù)處理，電鍍及鍍后處理三個階段。</p><div

除氫為了消除高的強(qiáng)度鋼零件電鍍過程中因酸洗及滲入氫元素造成氫脆斷裂，在電鍍鋅鎳合金12h之后，采用熱風(fēng)循環(huán)電熱鼓風(fēng)干燥箱除氫:溫度190～210℃，時間為8h。(2) 鈍化150mL/LFinidip128鈍化液，pH值為2.8～3.0;溫度25～45℃，時間30～60s。(3) 封閉780～820mL/LFinigard105封閉劑，pH值8.8～9.2，溫度20～30℃，時間20～30s。在生產(chǎn)過程中，采用ISO17075:2007或DIN53314:2006方法對鈍化膜中的六價(jià)鉻進(jìn)行檢測，執(zhí)行GMW3034鍍鋅鎳層六價(jià)鉻含量的規(guī)定，零件電鍍、鈍化后放置1個月，膜層中六價(jià)鉻含量<0.01μg/cm2為合格。電鍍鋅鎳合金是一種適合鋼鐵緊固件的可靠的防護(hù)層。表面處理鋅鎳合金生產(chǎn)供應(yīng)</p><p
