摘　　要：研究了在(Ni-P)-纳米WC复合刷镀液中添加阴离子型表面活性剂SDS、阳离子型表面活性剂PEI、非离子型表面活性剂OP对分散体系分散效果的影响。结果表明:表面活性剂能有效阻止复合刷镀液中微粒的絮凝、团聚,其用量对复合刷镀液分散效果有显著的影响。当阴离子型表面活性剂SDS的质量浓度为0.2 g/L,阳离子型表面活性剂PEI为0.8 g/L时,刷镀液中沉降粉体体积最小,添加非离子型表面活性剂OP的分散体系分散效果较差。The impact of anion surfactant SDS, cation surfactant PEI, non-ionic surfactant OP added in the composite brush plating bath on the dispersity of nano-WC is investigated, The results show that surfactants can effectively prevent particles in the bath from flocculation and aggregation, therefore have an obvious impact on the dispersity of the composite brush plating bath. When the mass concentration of cation surfactant PEI is 0.8 g/L and anion surfactant SDS is 0.2 g/L in the bath,nanometer WC will obtain the best dispersity. Non-ionic surfactant OP shows a worse effect on nanometer WC dispersity.
