style="text-indent:25px">化學(xué)鍍鎳沉積的特性：①以次磷酸鈉為還原劑時，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，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。</p><p style="text-indent:25px">用次磷酸鹽作還原劑的化學(xué)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(dá)99.5%以上。剛沉積出來的化學(xué)鍍鎳層是無定型的，呈非晶型薄片狀結(jié)構(gòu)物質(zhì)。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(xué)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(xué)鍍鎳廢液中含有蘋果酸、酒石酸和檸檬酸等絡(luò)合劑時，可使用CaO調(diào)節(jié)廢液的pH值。</p><div
