摘要

研制了一种新型掺铈磷酸锌（Ce-ZP）复合涂层，以提高其在海洋环境中的耐腐蚀性能和摩擦学性能。XRD， XPS， IR和Raman光谱证实了铈成功地掺入到Zn3(PO4)2晶格中，而ESEM和EDS分析显示了均匀的微观结构。将Ce-ZP复合材料掺入环氧-酚醛-聚四氟乙烯基体中，具有低摩擦、高耐磨性和优异的防腐蚀性能。电化学研究表明Ce3+和Zn2+之间存在协同效应，形成钝化膜，延长了涂层的使用寿命。与传统的磷酸锌抑制剂相比，Ce-ZP表现出更快的活化、更好的耐久性和更高的稳定性。摩擦学分析证实，PTFE提供了润滑，Ce-ZP增强了机械强度，协同耐蚀磨损减轻了磨损-腐蚀耦合损伤。这些发现表明Ce-ZP涂层为高盐度和腐蚀性海洋环境提供了一种很有前途的解决方案。

Trivalent cerium-doped zinc phosphate composite coating: A novel solution to the wear-corrosion coupling issue

A novel cerium-doped zinc phosphate (Ce-ZP) composite coating was developed to enhance corrosion resistance and tribological performance in marine environments. XRD, XPS, IR, and Raman spectroscopy confirmed successful cerium incorporation into the Zn₃(PO₄)₂ lattice, while ESEM and EDS analyses demonstrated a uniform microstructure. The Ce-ZP composite, incorporated into an epoxy-phenolic-PTFE matrix, exhibited low friction, high wear resistance, and superior corrosion protection. Electrochemical studies revealed a synergistic effect between Ce³⁺ and Zn²⁺, forming passivation films that prolonged the coating’s lifespan. Compared to traditional zinc phosphate inhibitors, Ce-ZP demonstrated faster activation, improved durability, and enhanced stability. The tribological analysis confirmed that PTFE provided lubrication, Ce-ZP reinforced mechanical strength, and the synergistic corrosion-wear resistance mitigated wear-corrosion coupling damage. These findings indicate that Ce-ZP coatings offer a promising solution for high-salinity and corrosive marine environments.

期刊介绍： Surface and Coatings Technology is an international archival journal publishing scientific papers on significant developments in surface and interface engineering to modify and improve the surface properties of materials for protection in demanding contact conditions or aggressive environments, or for enhanced functional performance. Contributions range from original scientific articles concerned with fundamental and applied aspects of research or direct applications of metallic, inorganic, organic and composite coatings, to invited reviews of current technology in specific areas. Papers submitted to this journal are expected to be in line with the following aspects in processes, and properties/performance: A. Processes: Physical and chemical vapour deposition techniques, thermal and plasma spraying, surface modification by directed energy techniques such as ion, electron and laser beams, thermo-chemical treatment, wet chemical and electrochemical processes such as plating, sol-gel coating, anodization, plasma electrolytic oxidation, etc., but excluding painting. B. Properties/performance: friction performance, wear resistance (e.g., abrasion, erosion, fretting, etc), corrosion and oxidation resistance, thermal protection, diffusion resistance, hydrophilicity/hydrophobicity, and properties relevant to smart materials behaviour and enhanced multifunctional performance for environmental, energy and medical applications, but excluding device aspects.
