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 Ni-P-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 antifouling 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 / ( m²·h) at an active agent concentration of 0. 3 g / L and a PTFE concentration of 6 mL / L. At this point, the best antifouling performance was achieved for the composite coating.
