style="text-indent:25px">鎳合金鍍液主要分為兩種類型。一種為弱酸性體系，主要包括氯化銨型、氯化鉀型以及氯化銨和氯化鉀混合型，pH值一般為5．5左右。該鍍液成分簡(jiǎn)單，陰極電流效率一般都在95％以上，鍍液穩(wěn)定，容易操作，獲得的電鍍層中鎳的含量可超過(guò)l0％(質(zhì)量分?jǐn)?shù))。另一種是堿性鋅酸鹽鍍液，是近幾年來(lái)發(fā)展起來(lái)的，發(fā)展速度較快。獲得的電鍍層中鎳的含量一般在5％～l0％(質(zhì)量分?jǐn)?shù))。該鍍液的主要優(yōu)點(diǎn)是：鍍液分散性好，在較寬的電流密度范圍內(nèi)鍍層合金成分比例較均勻，鍍層厚度也均勻，對(duì)設(shè)備和工件腐蝕性小，工藝穩(wěn)定，成本低。此外堿性鋅鎳合金電鍍不能用于高碳鋼、鑄鐵零件的表面鍍覆。與電鍍鋅相似，為提高鋅鎳合金鍍層的耐蝕性，增加其裝飾性，改善涂料與基體金屬間的結(jié)合力，鋅鎳合金電鍍后也要進(jìn)行鉻酸鹽鈍化處理，使其表面生成一層穩(wěn)定性高、組織致密的鈍化膜。鋅鎳合金的鈍化膜有無(wú)色、黃色、黑色和土色四種。金山區(qū)鋅鎳哪家好</p><p
