航空航天工業(yè)為化學(xué)鍍鎳的使用大戶之一，比較突出的應(yīng)用實例是：美國俄克拉荷馬航空后勤中心，自1979年以來，以及西北航空公司自1983年以來均采用化學(xué)鍍鎳技術(shù)修復(fù)飛機(jī)發(fā)動機(jī)零件。普拉特－惠特尼公司的JT8D噴氣發(fā)動機(jī)雖已經(jīng)停產(chǎn)，可是迄今仍有上千臺這種發(fā)動機(jī)在波音727和麥道DC-9飛機(jī)上使用，原因是：一種高磷，壓應(yīng)力的化學(xué)鍍鎳技術(shù)用于修復(fù)JT8D六種型號的噴氣發(fā)動機(jī)的葉輪，確保了這種發(fā)動機(jī)的重新使用。在航空發(fā)動機(jī)的渦輪機(jī)或壓縮機(jī)的葉片上，通常鎳磷合金化學(xué)鍍厚為25～75um，以防止燃?xì)飧g，其疲勞強(qiáng)度的降低比電鍍鉻少25%。俄克拉荷馬航空后勤中心采用超厚層化學(xué)鍍鎳修復(fù)飛機(jī)零件，鍍厚達(dá)275～750um。原采用電鍍工藝時的返工率達(dá)50%，采用化學(xué)鍍鎳后合格率達(dá)90%以上，可見取得了明顯的經(jīng)濟(jì)效益。</p><p style="text-indent:25px">銅稱為特殊黃銅。常用的合金元素有硅、鋁、錫、鉛、錳、鐵與鎳等。在黃銅中加鋁能提高黃銅的屈服強(qiáng)度和抗腐蝕性，稍降低塑性。含鋁小于4%的黃銅具有良好的加工、鑄造等綜合性能。在黃銅中加1%的錫能改善黃銅的抗海水和海洋大氣腐蝕的能力，因此稱為“海軍黃銅”。錫還能改善黃銅的切削加工性能。黃銅加鉛的主要目的是改善切削加工性和提高耐磨性，鉛對黃銅的強(qiáng)度影響不大。錳黃銅具有良好的機(jī)械性能、熱穩(wěn)定性和抗蝕性；在錳黃銅中加鋁，還可以改善它的性能，得到表面光潔的鑄件。黃銅可分為鑄造和壓力加工兩類產(chǎn)品，上海眾霖五金有限公司為上海眾新五金有限公司下屬子公司，主要從事各類金屬零件電鍍業(yè)務(wù)，其鍍種主要有：鍍鋅、鋅鎳合金、化學(xué)鍍鎳、電鍍鎳、鍍金、鍍銀、鍍錫等。如您需要鍍錫業(yè)務(wù)，請聯(lián)系我們。電鍍生產(chǎn)線找哪家？上海眾霖讓您放心電鍍。</p><div

style="text-indent:25px">早期的鍍錫常采用熱浸工藝，這種生產(chǎn)方式需消耗較多能源，不*較難獲得均勻光潔的鍍層，而且易造成錫的浪費，相繼人們成功地研究了堿性鍍錫、中性鍍錫和酸性鍍錫并穩(wěn)定地運用于生產(chǎn)實踐中。以錫酸鈉為主的堿性鍍錫溶液通常采用氫氧化鈉和氫氧化鉀作絡(luò)合劑進(jìn)行電鍍，自20世紀(jì)40年代以來，幾乎取代了所有的較古老的鍍錫工藝；隨著添加劑研究和開發(fā)的深入，特別是裝飾性的晶紋鍍錫的使用，酸性硫酸亞錫鍍錫有了很大的發(fā)展。在簡單的硫酸及硫酸亞錫溶液中加入抗氧化劑和其他附加劑可獲得質(zhì)量良好的無光或光亮的鍍層。氟硼酸鹽鍍錫工藝雖然有優(yōu)越性，但是由于環(huán)境保護(hù)的原因，現(xiàn)在已經(jīng)不推薦使用。另外，為了在鉛基或鋅基上獲得結(jié)合良好的錫鍍層，使得中性鍍錫電解液也得到一定的運用和發(fā)展。高質(zhì)量鍍錫，高效率，眾霖讓您放心鍍錫。安徽省鋁材亮光鍍錫商家</p><p
