化學(xué)鍍鎳是指在一定條件下，水溶液中的金屬離子被還原劑還原，并且沉淀到固態(tài)基體表面的過(guò)程。這一過(guò)程與置換鍍不同，其鍍層是可以不斷增厚，且施鍍金屬本身也具有催化能力，那么化學(xué)鍍鎳層的作用都有哪些呢？下面就為大家具體介紹一下： </p> <p> （1）利用次磷酸鈉作為還原劑的化學(xué)鍍鎳過(guò)程得的是Ni-P合金，控制鍍層中的磷含量可以得Ni-P非晶態(tài)結(jié)構(gòu)鍍層。鍍層致密、孔隙率低、耐腐蝕性能均優(yōu)于電鍍鎳。 </p> <p> （2）化學(xué)鍍鎳層的鍍態(tài)硬度為450~600HV，經(jīng)過(guò)合理的熱處理后，可以達(dá)到1000-1100HV，在某些情況下，甚至可以代替硬鉻使用。 </p> <p> （3）根據(jù)鍍層中的含磷量，可以控制鍍層為磁性或非磁性。 </p> <p> （4）鍍層的磨擦系數(shù)低，可以達(dá)到無(wú)油潤(rùn)滑的狀態(tài)，潤(rùn)滑性與抗金屬磨損性方面也優(yōu)于電鍍。 </p> <p> （5）低磷鍍層具有良好的可焊性。 </p> <p> 除此之外，化學(xué)鍍鎳可以簡(jiǎn)化電鍍工藝，尤其采用膠體鈀直接活化時(shí)更是如此，化學(xué)鍍鎳層上可直接進(jìn)行光亮鍍鎳加厚，化學(xué)鍍鎳溶液較化學(xué)鍍銅溶液穩(wěn)定，沉積速度快。福建汽車(chē)配件化學(xué)鍍鎳加工學(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55.</p><div

style="text-indent:25px">當(dāng)然，與很多技術(shù)一樣，化學(xué)鍍鎳自身也存在很多缺點(diǎn)：⑴與電鍍鎳相比，鍍液的組成復(fù)雜，某些原材料要求較為苛刻。⑵化學(xué)鍍的操作比較麻煩，鍍覆中必須不斷進(jìn)行分析補(bǔ)加，調(diào)整pH。⑶化學(xué)鍍?nèi)芤罕旧硎且粋€(gè)熱力學(xué)不穩(wěn)定體系，容易發(fā)生分解等事故。⑷對(duì)比電鍍，化學(xué)鍍的鍍速慢，大多化學(xué)鍍的鍍速在10-30μm/h之間。⑸很多化學(xué)鍍的工作溫度都在90℃左右，維持這個(gè)溫度也要消耗大量能源。⑹化學(xué)鍍層的裝飾性不如電鍍，光亮性不足。。。。</p><p style="text-indent:25px">用化學(xué)鍍鎳沉積的鍍層，有一些不同于電沉積層的特性。①以次磷酸鈉為還原劑時(shí)，由于有磷析出，發(fā)生磷與鎳的共沉積，所以化學(xué)鍍鎳層是磷呈彌散態(tài)的鎳磷合金鍍層，鍍層中磷的質(zhì)量分?jǐn)?shù)為1%～l5%，控制磷含量得到的鎳磷鍍層致密、無(wú)孔，耐蝕性遠(yuǎn)優(yōu)于電鍍鎳。以硼氫化物或氨基硼烷為還原劑時(shí)，化學(xué)鍍鎳層是鎳硼合金鍍層，硼的含量為1%～7%。只有以肼作還原劑得到的鍍層才是純鎳層，含鎳量可達(dá)到99．5%以上。②硬度高、耐磨性良好。電鍍鎳層的硬度*為l60～180HV，而化學(xué)鍍鎳層的硬度一般為400～700HV，經(jīng)適當(dāng)熱處理后還可進(jìn)一步提高到接近甚至超過(guò)鉻鍍層的硬度，故耐磨性良好，更難得的是化學(xué)鍍鎳層兼?zhèn)淞肆己玫哪臀g與耐磨性能。③化學(xué)穩(wěn)定性高、鍍層結(jié)合力好。在大氣中以及在其他介質(zhì)中，化學(xué)鍍鎳層的化學(xué)穩(wěn)定性高于電鍍鎳層的化學(xué)穩(wěn)定性。與通常的鋼鐵、銅等基體的結(jié)合良好，結(jié)合力不低于電鍍鎳層和基體的結(jié)合力。④由于化學(xué)鍍鎳層含磷（硼）量的不同及鍍后熱處理工藝的不同，鍍鎳層的物理化學(xué)特性，如硬度、抗蝕性能、耐磨性能、電磁性能等具有豐富多彩的變化，是其他鍍種少有的。所以，化學(xué)鍍鎳的工業(yè)應(yīng)用及工藝設(shè)計(jì)具有多樣性和**性的特點(diǎn)?；瘜W(xué)鍍鎳合金層的耐蝕、耐磨性能。如形狀復(fù)雜的散熱器、齒輪、噴油嘴、制動(dòng)瓦片、減振器等等2.</p><div

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。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00.河南銅化學(xué)鍍鎳</p><p

機(jī)械法除銹是對(duì)工件表面進(jìn)行噴砂、研磨、滾光或擦光等機(jī)械處理,在工件表面獲得整平的同時(shí)除去表面銹層?；瘜W(xué)法除銹是用酸或堿溶液對(duì)金屬制品進(jìn)行強(qiáng)浸蝕處理使制品表面的銹層通過(guò)化學(xué)作用和浸蝕過(guò)程所產(chǎn)生氫氣泡的機(jī)械剝離作用而除去。電化學(xué)除銹是在酸或堿溶液中對(duì)金屬制品進(jìn)行陰極或陽(yáng)極處理除去銹層。陽(yáng)極除銹是化學(xué)溶解、電化學(xué)溶解和電極反應(yīng)析出的氧氣泡的機(jī)械剝離作用而去除。陰極除銹是化學(xué)溶解和陰極析出氫氣的機(jī)械剝離作用而去除。用于化學(xué)鍍鎳前處理除銹工藝基本與電鍍的除銹工藝相同。 </p> <p> 化學(xué)沉鎳工藝是為了增強(qiáng)工件表面的耐腐蝕性和耐磨性，對(duì)工件表面顏色的改變和美觀(guān)度有很好的處理。通常工件在沒(méi)進(jìn)過(guò)處理的時(shí)候與空氣接觸，容易與空氣中的氧氣和水產(chǎn)生反應(yīng)從而氧化。比如說(shuō)銹就是氧化的一種現(xiàn)象?；瘜W(xué)鍍鎳工藝就可以隔離空氣與工件的接觸。簡(jiǎn)單的來(lái)說(shuō)就是將一種金屬離子以固態(tài)的形式附在工件表面?？梢愿鶕?jù)時(shí)間和水溶液中金屬離子的密度適當(dāng)增加電鍍層?；瘜W(xué)鍍鎳的保護(hù)，不*是一種物理保護(hù)，也增加工件的耐磨能力，也能增加工件的使用時(shí)間。山東紫銅化學(xué)鍍鎳加工廠(chǎng)家</p><p
