The dispersion and non-agglomeration of hard reinforcement particles in the electrolytic bath play a vital role in the electrodeposition of composite coatings. Hence, the influences of surfactant types i.e., anionic (sodium dodecyl sulphate, SDS), cationic (cetyltrimethylammonium bromide, CTAB), and non-ionic (polyethylene glycol, PEG), on the characteristics and properties of Ni-HEA composite coatings have been studied. The CoCrMoNiW HEA particles are fabricated through mechanical alloying of elemental powders. The x-ray diffraction analysis reveals mixed phase consisting of BCC phase with minor quantity of FCC phase in the mechanically alloyed HEA particles. The coating prepared with SDS surfactant achieved the highest thickness, approximately 140 μm. The critical load of 57 N in the scratch test, Vickers hardness number of 721 VHN, coefficient of friction of 0.28, and specific wear rate of 1.9 × 10<sup>−7</sup> mg/N-m were obtained for the composite coatings fabricated using SDS surfactant, these represent the highest performance values among all the fabricated coatings. The corrosion resistance is also high for the composite coating obtained using SDS surfactant (0.13 mpy) compared to the other coatings. The superior properties of the composite coating produced with SDS surfactant can be attributed to the higher zeta potential of the HEA particles, which promotes better dispersion in the electrolyte, which contributes to the uniform and stable dispersion of HEA particles without agglomeration, leading to the homogeneous distribution of HEA particles in the electrodeposited composite coating.</div></div>","PeriodicalId":22009,"journal":{"name":"Surface & Coatings Technology","volume":"515 ","pages":"Article 132658"},"PeriodicalIF":6.1,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145046035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional toxic antifouling coatings contribute to environmental accumulation and biological resistance. Although the nanocatalytic antifouling strategy based on algal enzyme mechanisms shows promise, its effectiveness is limited by resin-based immobilization methods that hinder the exposure of active sites. In this study, we propose an innovative strategy that integrates plasma electrolytic oxidation (PEO) with chemical etching and a solvothermal method to in-situ construct a PEO/UiO-66(Ce) nanozyme coating on the titanium alloy surface. The nanozymes are uniformly anchored on the surface of the TiO<sub>2</sub> porous ceramic layer through hydroxyl interactions and confinement with the hydroxyl-rich nanonetwork, thereby ensuring good structural stability. The sufficient exposure of the active sites facilitates the efficient conversion of H<sub>2</sub>O<sub>2</sub> and Br<sup>−</sup> to HOBr at the catalytic interface. As a result, the PEO/UiO-66(Ce) coating exhibits excellent haloperoxidase-like activity (HPO) and remarkable performance stability. Antibacterial tests show that the PEO/UiO-66(Ce) coating achieves a 97.8 % antibacterial rate against <em>E. coli</em> in the presence of H<sub>2</sub>O<sub>2</sub> and Br<sup>−</sup>. Compared to the original TA1, PEO/UiO-66(Ce) significantly reduces the attachment of marine algae, with a coverage rate of only 3.4 % after three days of immersion in <em>Halamphora</em> sp. suspension, which is substantially lower than the 27.6 % observed for TA1. Furthermore, its corrosion current density in a 3.5 % NaCl solution is significantly lower than that of pure TA1.
