plating），也可以稱為自催化電鍍（Autocatalytic plating）[1]。具體過(guò)程是指：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)基體表面上的過(guò)程。ASTM B374（ASTM，美國(guó)材料與試驗(yàn)協(xié)會(huì)）中定義為Autocatalytic plating is “deposition of a metallic coating by a controlled chemical reduction that is catalyzed by the metal or alloy being deposited”。這一過(guò)程與置換鍍不同，其鍍層是可以不斷增厚的[2]，且施鍍金屬本身也具有催化能力。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88.</p><div style="width:100%;text-align: center;"><img style="max-width:

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>
