表面工程技术在海洋工程装备中的应用

随着我国对海洋资源开发和利用的快速发展，对先进海洋工程装备的需求日益强烈，尤其是对某些关键部件的表面性能要求越来越高。然而，单从提高材料自身性能的角度来满足对高性能的要求几乎是不可能的。表面工程技术是提高材料表面性能的重要方法，它能够在不破坏材料自身性能的前提下，对材料表面性能进行强化或再生，使材料或部件表面具备耐磨、耐蚀、抗氧化、耐热、绝缘、密封和隔热等性能中的一种或几种。因此，表面工程技术已成为实现海洋工程装备材料最终性能的重要手段。对海洋工程装备中涉及到的材料表面改性技术、应用和发展进行了综述。最后，指出了一些重要问题，展望了将来的研究方向。

Applications of Surface Engineering Technology in Marine Engineering Equipment

With the rapid development and application of marine resources in China , the demands for advanced marine engineering equipments especially for the surface properties of key components of the equipments become more and more urgent.However, it is almost impossible to obtain the high performance only by improving properties of materials itself . Surface engineering technology is an important method in improving surface properties of materials .It can strengthen or re-generate the surface properties of materials and develop one or more functional properties on the surfaces of materials or components, such as wear resistance, corrosion resistance, oxidation resistance, heat resistance, insulation, sealing and thermal insulation, without destroying the properties of the materials itself.So it is necessary for the materials of marine engineering equipments to obtain the final performance by surface engineering technology .Surface engineering technologies applied in marine engineering equipments are summarized , and the progress and application of the technologies are re-viewed .In the end, some important problems and future research direction are pointed out .
