Abstract Cavitation and marine organisms are two obstacles when ship propellers keep propulsion efficiency. In this paper, the comprehensive performance of the propeller coating were from laboratory performance evaluation and actual ship application research,. The laboratory has carried out the observation of the surface morphology, the calculation of the surface energy and the measurement of the surface roughness of the propeller coating. Compared with traditional self-polishing antifouling coating, the propeller coating has a smoother surface. The cavitation test showed that after 100 h of hedging, the surface of the propeller coating had only a slight loss of gloss and the weight loss was less than 5 mg. The hydrodynamic performance test results showed that the propeller coating of the has no effect on the hydrodynamic performance. After the use on ship propellers for a period of 16 months, composite coating matched well only with minor damage on the leading edge, but none diffusion under the coating layer. And also marine organisms on blades of propeller could be washed away easily with high pressure water.

| About author:: Weiwei Cong, doctor, senior engineer. She has been engaged in the research and development of marine anti-fouling coatings and anti-corrosion coatings for more than ten years and is a technical leader in the field of coatings. In recent years, she has presided over and completed nearly ten scientific research projects of the Ministry of Science and Technology, the Ministry of Industry and Information Technology, the Military Science and Technology Commission, the National Defense Science and Technology Commission, and the Provincial and Municipal Science and Technology Commission. National major engineering models, deep-sea engineering equipment, large floating platforms and underwater weapons and equipment have been promoted and applied. The formation of a series of excellent performance antifouling coating products with independent intellectual property rights, effectively breaking the technology monopoly of international multinational coating companies, and making major contributions to the country's economic and national defense construction. |
