貴金屬電鍍通常都使用不溶性陽(yáng)極，且為導(dǎo)電良好，會(huì)使用貴金屬不溶解性陽(yáng)極(如白金)。陰極一般指的就是鍍件，但此處所述的陰極為鍍件導(dǎo)電用的陰極導(dǎo)電頭，一般陰極導(dǎo)電頭使用銅合金或不銹鋼材料，必須考慮導(dǎo)電，耐蝕，作業(yè)，成本，方可定材料。而陰極導(dǎo)電頭與鍍件接觸需良好，且摩擦越小越好。17.攪拌器：為促使電鍍效率，增加電鍍均勻度，提高電流密度，故必須加強(qiáng)攪拌效果。一般有用強(qiáng)水流攪拌，陰極震蕩攪拌，超音波攪拌，空氣攪拌等方式。大型電鍍?cè)O(shè)備烘道被鍍的零件為陰極，與直流電源的負(fù)極相連，金屬陽(yáng)極與直流電源的正極聯(lián)結(jié)，陽(yáng)極與陰均浸入鍍液中。</p><div

1.pH值的影響 </p> <p> 鍍液中的pH值可以影響氫的放電電位﹐堿性?shī)A雜物的沉淀﹐還可以影響絡(luò)合物或水化物的組成以及添加劑的吸附程度。但是﹐對(duì)各種因素的影響程度一般不可預(yù)見(jiàn)。比較好的pH值往往要通過(guò)試驗(yàn)決定。在含有絡(luò)合劑離子的鍍液中﹐pH值可能影響存在的的各種絡(luò)合物的平衡﹐<而必須根據(jù)濃度來(lái)考慮。電鍍過(guò)程中﹐若pH值增大﹐則陰極效率比陽(yáng)極效率高﹐pH值減少則反之。通過(guò)加入緩沖劑可以將pH值穩(wěn)定在一定范圍。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p><p> 第四節(jié) 金屬的電積過(guò)程 </p> <p> 電鍍過(guò)程是鍍液中的金屬離子在外電場(chǎng)的作用下﹐經(jīng)電極反應(yīng)還原成金屬原子并在陰極上進(jìn)行金屬沉積的過(guò)程。下圖(1-2)是電沉積過(guò)程示意圖﹐完成電沉積過(guò)程必須經(jīng)過(guò)以下三個(gè)步驟﹕ </p> <p> 液相傳質(zhì)﹕鍍液中的水化金屬離子或絡(luò)離子從溶液內(nèi)部向極界面遷移﹐到達(dá)陰極的雙電層溶液一側(cè)。 </p> <p> 電化學(xué)反應(yīng)﹕水化金屬離子或絡(luò)離子通過(guò)雙電層﹐并去掉它周?chē)乃肿踊蚺湮惑w層﹐從陰極上得電子生成金屬原子。有三種方式﹕電遷移﹐對(duì)流和擴(kuò)散。 </p> <p> 電結(jié)晶﹕金屬原子沿金屬表面擴(kuò)散到結(jié)晶生長(zhǎng)點(diǎn)﹐以金屬原子態(tài)排列在晶格內(nèi)﹐形成鍍層。 </p> <p> 電鍍時(shí)﹐以上三個(gè)步驟是同時(shí)進(jìn)行的﹐但進(jìn)行的速度不同﹐速度最慢的一個(gè)被稱(chēng)為整個(gè)沉積過(guò)程的控制性環(huán)節(jié)。不同步驟作為控制性環(huán)節(jié)﹐的電沉積結(jié)果是不一樣的。由于鄰近電極表液層的濃度與溶液主體的濃度發(fā)生差異而產(chǎn)生的極化稱(chēng)濃差極化。</p><div
