摘要 空泡腐蚀及海生物污损是制约螺旋桨推进性能发挥的主要障碍。本工作结合实验室性能评价及实船应用研究对设计制备的螺旋桨防护涂层进行了综合性能的考察。在实验室内对螺旋桨防护涂层进行了表面形貌的观察、表面能的计算及表面粗糙度的测量,与传统的自抛光防污涂层相比,螺旋桨防护涂层具有更加平滑的表面。抗空蚀试验表明,经过100 h对冲,螺旋桨防护涂层表面仅有轻微失光,且失重小于5 mg。水动力性能测试结果表明涂覆螺旋桨防护涂层后对水动力性能无影响。16个月的实船应用结果表明,螺旋桨防护涂层整体应用效果良好,仅导边处有小面积区域涂层破损,但无膜下扩散现象,表面附着的污损生物可轻易被高压水冲掉。研究结果表明,螺旋桨防护涂层对保障螺旋桨推进效率,延长其服役寿命具有重要意义。

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.
