style="text-indent:25px">掛鍍和滾鍍是兩種常用的電鍍方法，這兩種方法適用于各種五金、電力配件等加工，但是兩種電鍍方法還是有一定區(qū)別的。掛鍍適合用在一般尺寸的制品，是使用方式較為普遍的一種，在鍍膜開(kāi)始時(shí)，需要吧鍍件掛在導(dǎo)電性能較好的爪型掛具上，然后浸泡在電解液中，然后再兩邊適當(dāng)?shù)木嚯x放入陽(yáng)極，通電后使得金屬離子在零件表面沉積。滾鍍是將零件置于布滿小孔的滾筒中，內(nèi)有一條導(dǎo)線，與依靠鍍件自身的重量與導(dǎo)線作不固定接觸，滾桶在鍍液中慢慢滾動(dòng)，電流和鍍液經(jīng)過(guò)小孔出入滾桶，在滾筒轉(zhuǎn)動(dòng)的過(guò)程中實(shí)現(xiàn)金屬電沉積的方法。</p><div

style="text-indent:25px">另外可以從鍍銅工件和改善幾何因素入手去排查這些會(huì)在鍍銅過(guò)程中造成鍍層不均勻的情況。在鍍銅過(guò)程會(huì)發(fā)現(xiàn)，同樣一批掛件，有的工件鍍出來(lái)的層會(huì)發(fā)花發(fā)霧面，反復(fù)鍍層也是無(wú)法解決，造成這樣的問(wèn)題可能是上部工件與鍍液太近，所以其電力線比較低而影響質(zhì)量。改善鍍銅過(guò)程的幾何因素，可以采用象形陽(yáng)極法、保護(hù)陰極法、輔**極法、調(diào)整陽(yáng)極表面積法、控制鍍液導(dǎo)電空間法、多次鍍鉻法等方法，來(lái)改善電力線分布的均勻性，可以是單獨(dú)使用某一種方法，也可以是多種方法聯(lián)合使用。</p><div
