化學(xué)鍍鎳技術(shù)能廣為應(yīng)用的原因之一是鍍層具有優(yōu)越的耐蝕性能，它是陰極性鍍層，所以鍍層厚度及完整性是保護(hù)基材效果好壞的關(guān)鍵，否則反而加快基材的腐蝕，這點(diǎn)需充分予以重視。那么該如何提高化學(xué)鍍鎳的耐腐蝕性能呢？下面小編就為大家具體介紹一下： </p> <p> 基體質(zhì)量這是鍍層持量的基本保證，但往往被人們忽視。鍍前需了解工件材料的成分、狀態(tài)、冶金質(zhì)量及加工成型的過(guò)程，不適當(dāng)?shù)募庸?huì)造成應(yīng)力、微裂紋。工件上不應(yīng)有折疊、焊屑、毛刺、孔洞及砂眼等缺陷。鋼中的夾雜物，尤其是硫化物，不*影響鍍層的耐蝕性，還會(huì)毒化鍍液。 </p> <p> 鍍前處理基材上原有的潤(rùn)滑油或緩蝕劑是很難清洗凈的，處理不好不*會(huì)降低鍍層結(jié)合力，還會(huì)產(chǎn)生***而降低耐蝕性。除化學(xué)清洗法外，碳鋼基材常推薦使用電解清洗法，但這種清洗方法明顯地影響鍍層的耐蝕性。例如在堿性介質(zhì)中陽(yáng)極清洗會(huì)嗇鍍層孔隙率；陰極清洗雖然孔隙率低，但又可能引起氫脆。用堿性除銹劑，若換向周期性地反復(fù)清洗，即在85℃浸泡10分鐘、再陽(yáng)極清洗2分鐘，效果不如浸泡后改用陰極清洗更耐蝕。上海鐵化學(xué)鍍鎳加工處理學(xué)鍍鎳是一種化學(xué)溶液，在鋼部件的表面形成一層化學(xué)鍍鎳膜，有效的隔斷鋼部件與腐蝕性介質(zhì)的接觸5.</p><div

化學(xué)鍍鎳相信大家通過(guò)之前的介紹對(duì)其有了一定的了解了，化學(xué)鍍鎳是一種化學(xué)溶液，能與碳鋼等部件發(fā)生化學(xué)反應(yīng)，在鋼部件的表面形成一層化學(xué)鍍鎳膜，有效的隔斷鋼部件與腐蝕性介質(zhì)的接觸，從而達(dá)到防腐的目的。那么大家是否知道化學(xué)鍍鎳在不同行業(yè)的應(yīng)用呢？下面就為大家具體介紹一下： </p> <p> 1、電子、計(jì)算機(jī)行業(yè) </p> <p> 鋁鎂合金硬盤(pán)、線路板、薄膜電阻器、金屬元件等，利用化學(xué)鍍鎳合金可提高其耐磨、耐蝕性能和特殊的物理化學(xué)性能。 </p> <p> 2、機(jī)械制造工業(yè) </p> <p> 凡需要耐磨，耐蝕的零部件一般都可以用化學(xué)鍍鎳合金層來(lái)提高其壽命，如液壓軸、曲軸、傳動(dòng)鏈帶、齒輪、工卡量具等。 </p> <p> 3、模具行業(yè) </p> <p> 鎳合金鍍層因其耐磨、耐蝕、結(jié)合力強(qiáng)、固體自潤(rùn)滑性能以及工藝上的均勻，可控厚度等的優(yōu)勢(shì)，能夠起到強(qiáng)化模具的理想效果，**提高模具的抗磨損、抗擦傷、抗咬傷的能力，脫模容易，既延長(zhǎng)了模具壽命，又提高了模加工件的表面質(zhì)量，用ENP工藝處理模具時(shí)表面厚度均勻無(wú)變形，模具表面尺寸超差時(shí)，可以修復(fù)。
