style="text-indent:25px">化學鍍鎳層的性能有如下諸多優(yōu)點：⑴利用次磷酸鈉作為還原劑的化學鍍鎳過程得到的是Ni-P合金，控制鍍層中的磷含量可以得到Ni-P非晶態(tài)結構鍍層。鍍層致密、孔隙率低、耐腐蝕性能均優(yōu)于電鍍鎳。⑵化學鍍鎳層的鍍態(tài)硬度為450~600HV，經(jīng)過合理的熱處理后，可以達到1000-1100HV，在某些情況下，甚至可以代替硬鉻使用。⑶根據(jù)鍍層中的含磷量，可以控制鍍層為磁性或非磁性。⑷鍍層的磨擦系數(shù)低，可以達到無油潤滑的狀態(tài)，潤滑性與抗金屬磨損性方面也優(yōu)于電鍍。⑸低磷鍍層具有良好的可焊性。</p><p style="text-indent:25px">用次磷酸鹽作還原劑的化學鍍鎳溶液中鍍得的鍍層含有4%～15%的磷，是一種鎳磷合金，以硼氫化物或胺基硼烷作還原劑得到的鍍層才是純鎳層，含鎳量可達99.5%以上。剛沉積出來的化學鍍鎳層是無定型的，呈非晶型薄片狀結構物質。鍍層中磷含量主要決定于溶液的pH值，隨著pH值降低，磷含量增大。常規(guī)的酸性化學鍍鎳溶液中沉積出的鍍層含磷量為7%～12%，而堿性溶液中沉積的鎳層含磷量為4%～7%。此外，溶液的組成及各組分的含量和它們的相對比率，以及溶液的工作溫度等都對含磷量有一定的影響。化學鍍鎳液中可以添加各種絡合劑。</p><div

style="text-indent:25px">石油和天然氣是化學鍍鎳的重要市場之一，油田采油和輸油管道設備普遍地采用化學鍍鎳技術。典型的石油和天然氣工業(yè)腐蝕環(huán)境為井下鹽水、二氧化碳、硫化氫，溫度高達170～200℃，并伴有泥沙和其他磨粒沖蝕等等，腐蝕環(huán)境相當惡劣。低碳鋼油氣管道在如此苛刻的條件下，*有2～3個月的壽命。經(jīng)過50～100um厚的高磷化學鍍鎳層保護之后，其腐蝕速率降低到與哈氏合金相當?shù)某潭?。考慮到耐蝕合金價格昂貴，從性能價格比上講，碳鋼管道采用化學鍍鎳保護的技術經(jīng)濟性能較好。錫、銅和銅合金制件要先用鋁片接觸其表面上1-3分鐘，以加速化學鍍鎳。鹽城化學鍍鎳配方技術</p><p
