<br /> </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，新型電鍍?cè)O(shè)備值得信賴。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> <br /> </p>

<p> 掛具是電鍍加工**重要的輔助工具。它是保證被電鍍制品與陰極有良好連接的工具，同時(shí)也對(duì)電鍍鍍層的分布和工作效率有著直接影響的裝備。已經(jīng)有專業(yè)掛具生產(chǎn)和供應(yīng)商提供行業(yè)中通用的掛具并根據(jù)用戶需要設(shè)計(jì)和定做掛具。 </p> <p> 6.鍍前清洗設(shè)備 </p> <p> 超聲波清洗在電鍍前工藝應(yīng)用 </p> <p> 產(chǎn)品電鍍前處理工藝非常重要，一般的傳統(tǒng)工藝使用酸液對(duì)工件進(jìn)行處理，對(duì)環(huán)境污染較重，工作環(huán)境較差，同時(shí)，比較大的弊端是結(jié)構(gòu)復(fù)雜零件酸洗除銹后的殘酸很難沖洗干凈。工件電鍍后，時(shí)間不長(zhǎng)，沿著夾縫出現(xiàn)銹蝕現(xiàn)象，破壞電鍍層表面，嚴(yán)重影響產(chǎn)品外觀和內(nèi)在質(zhì)量。超聲波清洗技術(shù)應(yīng)用到電鍍前處理后，不僅能使物體表面和縫隙中的污垢迅速剝落，而且電鍍電鍍層牢固不會(huì)返銹。環(huán)保電鍍?cè)O(shè)備廠家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)生的極化稱濃差極化。</p><div

<br /> </p> <p> 電鍍工藝，對(duì)工件表面清潔度要求較高，而超聲波清洗技術(shù)是能達(dá)到此要求的理想技術(shù)。利用超聲波清洗技術(shù)，可以替代溶劑清洗油污；可以替代電解除油；可以替代強(qiáng)酸浸蝕去除碳鋼及低合金鋼表面的鐵銹及氧化皮。 </p> <p> 電鍍所需要的設(shè)備主要是整流電源、鍍槽、陽(yáng)極和電源導(dǎo)線，還有按一定配方配制的鍍液。要使電鍍過(guò)程具有科研的或工業(yè)的價(jià)值，需要對(duì)電鍍過(guò)程進(jìn)行控制，也就是要按照一定的工藝流程和工藝要求來(lái)進(jìn)行電鍍，并且還要用到某些輔助設(shè)備和管理設(shè)備，比如，過(guò)濾機(jī)、加熱或降溫設(shè)備、化驗(yàn)設(shè)備、檢測(cè)設(shè)備等。 </p><p> 在盛有電鍍液的鍍槽中，經(jīng)過(guò)清理和特殊預(yù)處理的待鍍件作為陰極，用鍍覆金屬制成陽(yáng)極，兩極分別與直流電源的正極和負(fù)極聯(lián)接。電鍍液由含有鍍覆金屬的化合物、導(dǎo)電的鹽類、緩沖劑、pH調(diào)節(jié)劑和添加劑等的水溶液組成。通電后，電鍍液中的金屬離子，在電位差的作用下移動(dòng)到陰極上形成鍍層。陽(yáng)極的金屬形成金屬離子進(jìn)入電鍍液，以保持被鍍覆的金屬離子的濃度。在有些情況下，如鍍鉻，是采用鉛、鉛銻合金制成的不溶性陽(yáng)極，它只起傳遞電子、導(dǎo)通電流的作用。電解液中的鉻離子濃度，需依靠定期地向鍍液中加入鉻化合物來(lái)維持。電鍍時(shí)，陽(yáng)極材料的質(zhì)量、電鍍液的成分、溫度、電流密度、通電時(shí)間、攪拌強(qiáng)度、析出的雜質(zhì)、電源波形等都會(huì)影響鍍層的質(zhì)量，需要適時(shí)進(jìn)行控制。電鍍層比熱浸層均勻，一般都較薄，從幾個(gè)微米到幾十微米不等。</p><div

整平能力：整平能力（即微觀分散能力）是指在金屬表面上形成鍍層時(shí)，鍍液所具有的能使鍍層的微觀輪廓比基體表面更平滑的能力。它表達(dá)了基體金屬的粗糙度比較小，波穴的深度小于0.5mm，波峰與波谷的距離很小的表面上鍍層分布的均勻性。 </p> <p> <br /> </p> <p> 或麻點(diǎn)：氫氣呈氣泡形式粘附在陰極表面上，阻止金屬在這些部位沉積，它只能沉積在氣泡的周圍，如果氫氣泡在整個(gè)電鍍過(guò)程中一直停留在陰極表面，則鍍好的鍍層就會(huì)有空洞或貫通的縫隙；若氫氣泡在電鍍過(guò)程中粘附得不牢固，而是間歇交替地逸出和粘附，那么這些部位將形成淺坑或點(diǎn)穴，在電鍍工業(yè)中通常稱它為或麻點(diǎn)。所謂極化就是指有電流通過(guò)電極時(shí)，電極電位偏離平衡電極電位的現(xiàn)象。新型電鍍?cè)O(shè)備值得信賴</p><p

電鍍需要一個(gè)向電鍍槽供電的低壓大電流電源以及由電鍍液、待鍍零件(陰極)和陽(yáng)極構(gòu)成的電解裝置。其中電鍍液成分視鍍層不同而不同，但均含有提供金屬離子的主鹽，能絡(luò)合主鹽中金屬離子形成絡(luò)合物的絡(luò)合劑，用于穩(wěn)定溶液酸堿度的緩沖劑，陽(yáng)極活化劑和特殊添加物（如光亮劑、晶粒細(xì)化劑、整平劑、潤(rùn)濕劑、應(yīng)力消除劑和抑霧劑等）。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。因此，這是一個(gè)包括液相傳質(zhì)、電化學(xué)反應(yīng)和電結(jié)晶等步驟的金屬電沉積過(guò)程。新型電鍍?cè)O(shè)備值得信賴</p><p
