style="text-indent:25px">電鍍鋅鎳合金是取代鍍鋅工藝的較佳選擇,其獨(dú)到之處,不*鍍層防護(hù)性能遠(yuǎn)遠(yuǎn)超過普通鍍鋅,而且氯化物鍍鋅溶液可以直接轉(zhuǎn)化為氯化物鋅鐵合金溶液。上這種新工藝很容易,只需將原溶液進(jìn)行大處理,基本去除原有光亮劑,加入鐵鹽和新的光亮劑就成為新工藝了,這種調(diào)整改變基本不增加投資。通過氯化鉀鍍鋅與鋅鐵合金的生產(chǎn)比較,我們有如**會:鋅鐵合金鍍層比鉀鹽鍍鋅層結(jié)晶更細(xì)小致密,防護(hù)性能更優(yōu)異。鉀鹽鍍鋅溶液分散能力不如鋅鐵合金溶液好,80ｄｍ2的工件,鉀鹽鍍鋅時(shí),平面件中間部位呈蛋形發(fā)霧不亮。轉(zhuǎn)化為鋅鐵合金鍍液后這種現(xiàn)象消除,整個(gè)色澤光亮一致。鉀鹽鍍鋅低鉻彩鈍易脫膜,白鈍易變色,轉(zhuǎn)化為鋅鐵合金鍍液后,這種現(xiàn)象未出現(xiàn)過。鉀鹽鍍鋅特別是滾鍍液每月需大處理一次,否則不能正常生產(chǎn),轉(zhuǎn)化為鋅鐵合金鍍液后一年不處理照常生產(chǎn)。鍍鋅鐵合金的綜合成本低于鉀鹽鍍鋅,有較好的經(jīng)濟(jì)效益。</p><p style="text-indent:25px">電鍍鋅鎳合金的特點(diǎn)有哪些?1.優(yōu)異的耐腐蝕性。同樣厚度時(shí)，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(shí)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，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。評價(jià)任何電鍍工藝都要用到若干通用指標(biāo)。</p><div
