Zn–Ni and Zn–Ni/PTFE coatings were produced by the electrodeposition technique. The effect of PTFE particles concentration on co-deposition of these particles was investigated. Morphology of Zn–Ni and Zn–Ni/PTFE coatings along with their corrosion and tribological behavior were studied. The results showed that maximum incorporation of PTFE particles was obtained in the presence of 30 g l −1 of these particles in the bath. Clusters of cauliflower-like morphology of Zn–Ni film became coarser by the incorporation of PTFE particles. Potentiodynamic polarization and electrochemical impedance spectroscopy results revealed that Zn-14Ni film had the best corrosion resistance between all the samples. The corrosion resistance of the alloy film was decreased by the incorporation of PTFE particles. However, Zn–Ni/PTFE film had higher corrosion resistance than the steel substrate. According to hardness and wear results, while Zn-14Ni film had the highest hardness between all the sa...

PTFE对Zn-Ni电沉积物的特性，腐蚀和摩擦学行为的影响

Zn-Ni和Zn-Ni / PTFE涂层是通过电沉积技术生产的。研究了PTFE颗粒浓度对这些颗粒共沉积的影响。研究了Zn-Ni和Zn-Ni / PTFE涂层的形貌及其腐蚀和摩擦学行为。结果表明，在浴中存在30gl-1的这些颗粒时，获得了最大的PTFE颗粒掺入。Zn-Ni膜的花椰菜状形态簇由于加入PTFE颗粒而变得更粗糙。电位动力学极化和电化学阻抗谱结果表明，在所有样品中，Zn-14Ni膜具有最佳的耐蚀性。通过引入PTFE颗粒降低了合金膜的耐腐蚀性。然而，Zn-Ni / PTFE膜具有比钢基底更高的耐腐蚀性。从硬度和磨损结果来看，Zn-14Ni薄膜在所有合金中硬度最高。
