摘要

目前，海水冲刷和腐蚀现象这一主题正引起人们的广泛关注。因此，本研究涉及 CuPP 材料的合成和 Ni-Cu/CuPP 涂层的制备，以便在具有高应力和腐蚀特征的海洋环境中使用。结果表明，CuPP 能有效提高 Ni-Cu 涂层的耐磨性和长期耐腐蚀性，这归功于 "细晶粒强化 "和 "扩散强化"。此外，摩擦传递膜的形成和磨损机制的转变也是 Ni-Cu/CuPP 复合涂层具有优异耐磨性的主要原因。

A Ni-Cu/CuPP composite coating with good wear resistance and long-term corrosion resistance for seawater applications

At the present time, the subject of seawater scouring and corrosion phenomena is attracting considerable attention. Accordingly, the present study involved the synthesis of CuPP materials and the preparation of Ni-Cu/CuPP coatings for deployment in marine environments characterised by elevated stress and corrosion. The results show that CuPP can effectively enhance the wear resistance and long-term corrosion resistance of Ni-Cu coatings, which is attributed to ‘fine grain strengthening’ and ‘diffusion strengthening’. Furthermore, the formation of a friction transfer film and the transformation of the wear mechanism are the primary factors contributing to the exceptional wear resistance of the Ni-Cu/CuPP composite coatings.

期刊介绍： Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International. Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
