【導(dǎo)讀】這些復(fù)合鍍層的形成除了通。之加入到鍍層中。最常用的硬度高的彌散化合物是碳化硅，金剛石粉末，氧化鋁，碳化鈦，氮化硼，碳化鉻或碳化鎢。最近，含PTFE的化學(xué)鎳做為復(fù)合材料被使用。PTFE的聚合和鍍層中磷含量，耐磨性和抗腐蝕性。層有許多性能都優(yōu)于其它鎳鍍層[4]?；瘜W(xué)鎳復(fù)合鍍層結(jié)合了傳統(tǒng)化學(xué)鎳鍍層特有的性能例如復(fù)雜鑄型。濃度的顆粒，與電鍍相比，高濃度的顆粒必將出現(xiàn)高比例的聚合。依于還原劑被用于鍍液中。共沉積PTFE顆粒以水分散的形式被添加到溶液中[10,11]。二者通過大于300℃的熱處理后硬度值分。均勻分布在含量為的化學(xué)Ni-P基體上比重為。受非離子和陽離子表面活性劑的影響。擦傷和干潤滑性能和較低的摩擦系數(shù)。問題，可以以正常方式過濾溶液。鍍層在350℃下處理1小時能。到最合適的鍍液組成。坩堝過濾并加入蒸餾水混合至需求量。承裝鍍液的容器要定期更換，攪拌器被攪拌，為保持顆粒懸浮和保持溫度均勻。
