Abstract:
With the rapid development and application of marine resources in China, the demand for advanced marine engineering equipment especially for the surface properties of key components of the equipment 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 regenerate 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 equipment to obtain the final performance by surface engineering technology. Surface engineering technologies applied in marine engineering equipment are summarized, and the progress and application of the technologies are reviewed in this paper. In the end, some important problems and future research direction are pointed out
