| 目的 制备耐蚀减磨性能优异的碳纤维增强铝基复合涂层。方法 利用粉芯丝材技术制备碳纤维增强铝基复合粉芯丝材，再利用电弧喷涂技术将制备的复合粉芯丝材制备成复合涂层。对铝基涂层使用SEM、XRD进行微观形貌、物化性能检测，使用摩擦磨损试验机、电化学工作站、中性盐雾试验机等对涂层的摩擦学、耐腐蚀性能等进行检测，综合评价在涂层体系中添加碳纤维对铝基涂层性能的影响。结果 添加碳纤维的铝基复合涂层相较于纯Al涂层，其摩擦学性能得到显著提升，摩擦系数由纯Al涂层的~0.4下降至~0.2，磨损率由纯Al涂层的~2.0×10–3 mm3/(N.m)下降至~8×10–4 mm3/(N.m)，相关指标均下降了50%以上。同时，利用扫描电子显微镜观察涂层表面的磨痕及对磨副的划痕，并分析了铝基涂层的磨损机理，结果表明，Al/CFs复合涂层主要以磨粒磨损为主导机制，而纯Al涂层则以粘着磨损为主导机制。通过电化学工作站测试涂层的动电位极化曲线和Bode曲线分析涂层发生腐蚀的趋势，其电化学结果表明，添加碳纤维后不显著影响铝基涂层的耐腐蚀性能。进一步中性盐雾试验结果表明，中性盐雾试验720 h后，铝基涂层均未出现明显的腐蚀产物，涂层展现了优异的耐腐蚀性能。结论 利用粉芯丝材技术和电弧喷涂技术可以制备碳纤维增强铝基复合粉芯丝材及其涂层，在不影响原有铝涂层耐腐蚀性能的前提下，添加碳纤维可显著降低复合涂层的摩擦系数和磨损率，使涂层具有耐蚀减磨性能，可拓展铝基涂层在耐蚀减磨领域中的应用。 |

| With the development of the ocean economy in recent decades, such as oil and gas exploitation in deep ocean environment, marine equipment urgently needs advanced protective technologies against the special service environment like high speed, strong friction, lubrication, etc. How to further improve the properties of marine equipment such as corrosion resistance and abrasion resistance becomes the key problem. Thermal spraying has been proven to be an efficient surface protection technology, in particular in fabricating anti-corrosion coatings on marine equipment surfaces. Among the marine protective coatings developed in past decades, thermal sprayed aluminum coating is evidenced to be one of the most economical and efficient corrosion protection coating. However, compared with its excellent corrosion resistance in marine environment, the tribological properties of aluminum are poor, such as high friction coefficient and low lubrication, which limits its application. In order to improve the tribological properties of the aluminum coating, adding low friction materials like carbon based materials is a feasible way. The work aims to prepare carbon fiber reinforced aluminum-based anti-attrition composite coating. The carbon fiber reinforced aluminum-based (Al/CFs) composite powder core wire was fabricated, and the Al/CFs composite coating was prepared by arc spraying. The properties of the composite coating were characterized. The micromorphology and the physicochemical properties of the coating were examined by SEM and XRD. The tribological properties and corrosion resistance of the coating were tested by friction and wear testing machine, electrochemical workstation and neutral salt spray test chamber. The effect of carbon fibers on the properties of the Al-based coating was comprehensively evaluated. The results showed that the tribological properties of the Al-based composite coating with carbon fibers were significantly improved compared with the pure Al coating, with the friction coefficient decreasing from ~0.4 to ~0.2 and the wear rate decreasing from ~2.0×10–3 mm3/(N.m) to ~8×10–4 mm3/(N.m). Scanning electron microscopy (SEM) was used to examine the surface wear morphologies of the composite coating and its wear pairs, and the wear mechanism of the coating was also analyzed. It was found that the wear mechanism of the Al/CFs composite coating was mainly abrasive wear, while that of the pure Al coating was adhesive wear. The corrosion trend of the coating was tested by the electrodynamic polarization curve and the Bode curve. The electrochemical results showed that the addition of carbon fibers did not significantly affect the corrosion resistance of the Al-based coating. Further, neutral salt spray test also showed that all the Al-based coatings had excellent corrosion resistance with no obvious corrosion products found on the coating surface after 720 h NSS test. In summary, the Al/CFs composite powder core wire and its coating can be prepared by powder core wire technology and arc spraying. Addition of carbon fibers into the aluminum coating system can significantly reduce the friction coefficient and wear rate of the composite coating without affecting the corrosion resistance of the original aluminum coating. The composite coating reveals excellent anti-corrosion and anti-attrition performances and can expand the application of Al-based coating in the field of corrosion resistance and wear reduction. |
