除了冶煉過程中加入鎳，來改善不銹鋼的耐蝕性以外，鍍鎳，也是一種增強(qiáng)產(chǎn)品耐蝕性的一種好辦法。而以鎳和銅為基本材料的Monel合金，則更是廣泛應(yīng)用于各種泵、閥、石油冶煉設(shè)備、船舶及海洋工程設(shè)備中。 </p> <p> 耐熱合金的研發(fā)與應(yīng)用中，鎳可以***提高材料的高溫穩(wěn)定性。高溫電加熱器的熱絲，一般采用鎳鉻合金或者鎢基合金，殼子則多采用鎳基合金。鎳基陶瓷，耐磨性好，可以單獨(dú)使用，或作為復(fù)合結(jié)構(gòu)材料的耐磨層使用。在電池史中，鎳鎘電池經(jīng)濟(jì)使用，鎳氫電池前景無(wú)限。 </p> <p>

電鍍工作中怎樣控制化學(xué)鍍鎳層含磷量?化學(xué)鍍鎳層中的磷含量多少是對(duì)電鍍加工后的鎳鍍層的電阻率，以及防腐性能都有影響，含磷量在電鍍加工生產(chǎn)中是一個(gè)衡量產(chǎn)品性能的重要的指標(biāo)。一般我們區(qū)分為低磷，中磷，高磷鍍層，高磷化學(xué)鎳在鋼鐵、鋁合金、銅等五金電鍍件中應(yīng)較多，低磷化學(xué)鎳在塑料電鍍件應(yīng)用或底鍍層中應(yīng)用較多。 </p> <p> 高磷配方的磷含量是10-13%左右，所以操作中基本在這個(gè)范圍內(nèi)浮動(dòng)，不會(huì)超過很多。 </p> <p> 在電鍍加工為了獲得穩(wěn)定的鍍速與鍍層質(zhì)量，濃度，溫度，PH都是固定在一個(gè)較小的范圍內(nèi)，通過調(diào)整化學(xué)鍍鎳液的成分與含量控制化學(xué)鍍鎳層含磷量，適當(dāng)多加一些蘋果酸就能在一定范圍內(nèi)提高化學(xué)鎳鍍層的磷含量。 </p> <p> <br /> </p> <p> <br /> 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33.江西紫銅化學(xué)鍍鎳廠家</p><p style="text-indent:25px">化學(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1.湖南紫銅化學(xué)鍍鎳公司</p><p
