摘　　要：目的提高Ni-P-PTFE复合镀层的防垢性。方法采用化学镀的方法,在45#碳钢表面制备NiP-PTFE复合镀层,研究镀液中活性剂和PTFE(聚四氟乙烯)含量对复合镀层中PTFE含量、镀层结垢速率的影响,从而得到最佳施镀参数。结果随着活性剂含量的增加,镀层中PTFE含量先上升,后下降,而镀层的结垢率呈现出先下降、后上升的变化趋势。结论当镀液中活性剂含量为0.3 g/L,PTFE乳液添加量为6 mL/L时,镀层的结垢速率最低,为0.004 85 g/(m2·h),此时镀层的防垢性能最佳。Objective To improve the ant/fouling properties of Ni-P-PTFE composite coatings. Methods Electroless Ni-P-PTFE composite coating was prepared on the surface of 45# carbon steel by Electroless plating method, and the effects of active agents and Ni-P-PTFE content in the plating solution on the PTEE content and fouling rate of the electroless Ni-P-PTFE composite coating were investigated to get the best parameters. Results As the surfactant concentration increased, the PTFE content of coating increased and then decreased, while the fouling rate of the coating firstly decreased and then increased. Conclusions The fouling rate of the composite coating reached the minimum of 0. 004 85 g/（ mE . h） at an active agent concentration of 0.3 g/L and a PTFE concen-tration of 6 mL/L. At this point, the best antifoulin3erformance was achieved for the comuosite coating.
