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> 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?；罨瘯r(shí)鐵基體如用鹽酸活化會(huì)使腐蝕率上升，如果以稀硫酸活化效果就好一些，且時(shí)間越短越好?；罨褐胁荒苡镁徫g劑。基材中含鉛將使鍍層出現(xiàn)微孔、降低結(jié)合力，還毒化鍍液。這類基材不宜用硫酸活化，以25%HBF4為宜，先閃鍍一下也可。
