在所有海洋可再生能源中，潮汐能在长时间尺度上具有更高的持久性和可预测性。由于海洋环境恶劣，潮汐发电技术的发展存在障碍。特别是，对于增加的转子直径，材料的选择提出了需要解决的重大挑战，包括摩擦学环境，例如固体颗粒侵蚀、气蚀、高推力载荷对涡轮叶片尖端的影响，以及海水条件与此类摩擦学现象之间的协同作用。这项研究的重点是生产和测试各种先进材料和表面涂层，以研究潮汐环境中的两个主要摩擦学问题：基体切割和钢筋断裂。在我们之前的工作中，G10 环氧玻璃层压板在这种环境下进行了测试，结果揭示了摩擦学问题。在目前的工作中，G10 环氧玻璃层压板基耐腐蚀聚合物涂层已在我们之前的工作中和 NaCl 溶液中测试了沙粒尺寸范围。测试结果表明，涂层提高了复合材料在摩擦学行为方面的性能质量，并减弱了海水和摩擦学现象之间的协同作用。这表明在选择先进材料来制造潮汐涡轮机叶片方面取得了进展。
Tidal energy, of all marine renewables energies, possesses higher persistency and predictability over long time scales. Due to the aggressive marine environment, there are barriers in the development of tidal power generation technology. In particular, with regard to increased rotor diameter, the selection of material presents significant challenges to be addressed including the tribological environment, such as solid particle erosion, cavitation erosion, the effect of high thrust loading on the turbine blade tips, and the synergy between sea water conditions and such tribological phenomena. This research focuses on producing and testing a variety of advanced materials and surface coatings to investigate two main tribological issues in tidal environments: matrix cutting and reinforcement fracture. In our previous work, a G10 epoxy glass laminate was tested in this environment and the results revealed tribological issues. In this present work, G10 epoxy glass laminate base erosion resistant polymeric coatings have been tested for the range of sand particles size in our our previous work and in NaCl solution. The test results reveal that the coating has enhanced the quality of performance of the composite with respect to tribological behaviour, and has diminished the synergy between sea water and tribological phenomena. This indicates progress toward the selection of advanced materials to manufacture tidal turbine blades.
