Experimental Study on Interactive Wears of Abrasion, Cavitation and Corrosion for Simulating Surface Damage of Ships

  • 摘要: 海洋装备表面材料破坏的主要原因是冲蚀、空蚀和腐蚀及其交互作用,而量化其表面磨损程度对海洋装备材料和结构的设计具有重要意义。冲蚀、空蚀和腐蚀交互磨损试验台是研究海洋装备表面材料破坏的有效工具。通过流场数值对比分析,在研究冲蚀和空蚀交互作用的基础上,优化设计了冲蚀、空蚀和电化学腐蚀交互磨损综合试验台,完成了人造海水中,不同材料的舰船工作表面受到高速流体冲击产生的冲蚀、空蚀和电化学腐蚀交互磨损试验。结果表明:同一种金属材料冲蚀、空蚀和电化学腐蚀交互作用的失重量大于冲蚀、空蚀和自然腐蚀交互作用的失重量,高强度塑性金属材料的腐蚀磨损较为严重,其三者交互作用的磨损程度大于低强度塑性金属材料。
